NPM run dev runs the Vue project and reports an error: Node Sass does not yet support your current environment

Leave a reply

After importing the Vue project, #npm run dev reported an error:

1
2
error in ./src/pages/hello.vue
Module build failed: Error: Node Sass does not yet support your current environment.......

 

 

Roughly it is a failure to compile a certain vue file, because the module fails to be constructed, and node sass does not support the current environment [mainly node].

Let’s take a look at the node version first:

    #node –version

 

Upgrading the node version/node version is too high will cause node-sass incompatibility, then just install node-sass again.　

1
#npm i node-sass -D

　[<==>#npm install node-sass -save-dev]

How to Solve Error: Cannot find module ‘webpack/lib/RequestShortener’

Leave a reply

Farewell:

Error: Cannot find module’webpack/lib/RequestShortener’

This is really clueless. Later, there was an article to solve other similar error reporting methods, and I borrowed it, and it really worked!

  1. npm install webpack –save-dev // After the installation is successful, there will be a prompt to install webpack-cli again
  2. npm install webpack-cli –save-dev

After that, it’s okay~

Understand bugs: Nvidia drivers are “fragile.” Because of the execution of the apt-get Upgrade command, the kernel from 4.10 to 4.13, install the Nvidia driver will report an error, so put the kernel version back to 4.10 version, install again!

uname -r                       #Check the current kernel version
sudo apt-get remove linux-image-(version-number)-generic
For example
sudo apt-get remove linux-image-4.4.0-140-generic-generic # to remove the current kernel version



nvidia-smi # Use the command to view the GPU information after installing the graphics driver

Kernel version in the upgrade, will not delete the old version, just replace the old with the new version, only need to delete the new version of the kernel, the system will automatically descend to the old version, delete the new version of the kernel.

Install MySQL ODBC connector prompt error 1918 perfect solution (non installation of VC + + library method)

Local environment:
operating system – windows7 32 bit
MYSQL version – MYSQL Ver 14.14 Distrib 5.7.25, for Win32 (AMD64)
Execution process:

    start – control panel – systems and security – management tools – data source (ODBC) wanted to add MYSQL, found that MYSQL could not be found. An error was reported during the installation of mysql-Connector-ODBc-8.0.15-Win32 (mysql 5.7 supported) on the official website.

Error contents:

Try installing mysql-connector-odbc-5.1.13-win32.msi verification solution :(the current environment has all three versions of vc++ installed) install the lower version (5.1.13) successfully! The ODBC data source manager was able to successfully create the user data source.

Solution to “[dbnetlib] [connectionwrite (send()).] general network error”

Recently, I need to use Excel to generate a series of charts, the data is naturally obtained through sql server. The problem is that this excel has nearly 50 charts, and each chart has to be connected to DB to get the data. The problem comes, when refreshing all the time often encountered
“[DBNETLIB] [ConnectionWrite (send()). General network error. Check your network documentation” error. The initial judgment is definitely too much data connection caused by (for Excel rookies do not have the ability to solve from the Excel side). After a while Google, finally found a solution, maybe not the best, right as a record.

Possible causes.
This problem occurs because Windows Server 2003 and higher implements a security feature that reduces the size of the queue of concurrent TCP/IP connections to the server. This feature helps prevent denial-of-service attacks. Under high load conditions, the TCP/IP protocol may incorrectly recognize a valid TCP/IP connection as a denial-of-service attack. This behavior can lead to the problems described in the Symptoms section.

Solution.
This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if the registry is not modified correctly. Therefore, make sure you follow these steps carefully. For extra protection, back up the registry before modifying it. Then, if a problem occurs, you can restore the registry.
To resolve this issue, turn off this new feature by adding SynAttackProtect entry to the following registry entry for the computer that is running Microsoft SQL Server, which houses your BizTalk server database.

HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Tcpip \ \ Service Parameters

Settings

SynAttackProtect

Enter a DWORD value of 00000000. to do this, follow these steps:
Click Start, click Run, type regedit, and then click OK. Find and click on the following registry entry:

HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Tcpip \ \ Service Parameters

On the Edit menu, point to New, then click on the DWORD value. Type SynAttackProtect, and then press ENTER. Click Modify on the Edit menu. In the Value Data box, type 00000000. click OK. exit the Registry Editor.
Note To complete this registry change, you must restart the computer running SQL Server.

 

Installing VB6.0 under win7 (error accessing the ole Registry)

Some time ago, after the installation of vb6.0 in the flagship version of Win7, when opening the vb development environment, “OLE registry error access” (Chinese error description forgot to make a record) prompt error, after referring to the article reproduced below to install, after the completion of the installation, can normally run under Win7 vb development (I also had some small problems during the installation process, see the note in red at the end of the article), now the original article is recorded for future use.

 

There are thousands of legacy applications that need support, and people like me who speak VB6 need to install tools on our workstations in order to implement and test updates to these legacy applications and so on. It is also helpful when I need a quick tool to use in my daily work.

This process has been tested on Windows 7, both 32-bit and 64-bit with no problems. Here is how I installed visualbasic6 on my Windows 7 machine.

      1. Close the UAC.
      1. Insert the Visual Studio 6 CD.
      1. Exit the autorun setup.
      1. Browse to the root folder of the VS6 CD.
      1. Right-click on Setup.EXE and select Run as Administrator.
      1. For a warning about this and other program compatibility helpers, click Run Program.
      1. Click Next.
      1. Click “I accept the agreement” and then Next.
      1. Enter the name and company information and click Next.
      1. Select Custom Settings and click Next.
      1. Click Continue, and then OK.
      1. The installation will “think for itself” for about 2 minutes. You can verify the processing by launching Task Manager and checking the CPU usage of ACMSETUP.EXE.
      1. In the list of options, select the following:
      1. Microsoft Visual Basic 6.0ActiveXData AccessGraphics
      1. All other options should be unchecked. Click “Continue” and the installation process will continue.
      1. Finally, a Successful Completion dialog box will appear, where you can click Ok. At this point, Visual Basic 6 is installed.
      1. If you do not have the MSDN CD, clear the checkboxes in the next dialog box and click Next. You will receive a warning that MSDN is missing, but simply click Yes to accept it.
      1. Click Next to skip the Installshield installation. This is a very old version that you don’t want anyway.
      1. Click Next again to skip the installation of BackOffice, VSS, and SNA Server. Not required!
      1. In the next dialog box, clear the Register Now checkbox, and then click Finish

.The wizard will exit and you are done. You can find VB6 under Start, All program, Microsoft Visual Studio 6. Enjoy!

Update

You may notice that after successfully installing VB6 on Windows 7, working in the IDE is a bit slow. For example, resizing objects on a form can be a real pain.

After installing VB6, you will want to change the compatibility settings for the IDE executable.

Using Windows Explorer, browse to the location where you installed VB6. By default, the path is C:\Program Files\Microsoft Visual Studio\VB98\ Right-click on the VB6.exe program file and select properties from the context menu. click the Compatibility tab. Add a checkbox to each of the checkboxes:
Run this program in Windows XP compatibility mode (Service Pack 3) Disable visual themes Disable desktop combinations Disable display scaling High DPI settings

After changing these settings and starting the IDE, things should return to normal and the IDE should no longer be sluggish

How to Solve IBM MQ Connect Error Code 2035

Usually, MQ client and MQ server communication, using the MQ server connection channel service in the MCAUSER attribute specified by the user as the MQ client even come up with the user, if the MCAUSER attribute value is empty, use the MQ client in the operating system used by the user as the MQ client even come up with the user, communication, reported a 2035 error, is due to the client and server communication used by the user without permission, there are two solutions.
Method one:
If you set the MCAUSER property to MUSR_MQADMIN(CHANNEL definition name JMS_RECEIVE) in the server’s service connection CHANNEL definition: ALTER CHANNEL(JMS_RECEIVE) CHLTYPE(SVRCONN); MCAUSER(MUSR_MQADMIN) must ensure that the MUSR_MQADMIN user is a member of the MQM group as follows:
Usermod-g GroupName Username (change the group of the existing user)
Useradd-g GroupName Username (create new user and group)
Method 2:
If MQ channel definition on the server MCAUSER attribute values for vacant province, namely is empty, the MQ client can be used by the users to add to the MQ server’s operating system, for example, if the MQ client USES for the ADMIN user, the user is added to the MQ server ADMIN, and ensure the users in the MQM group MQ the server, and how to perform the necessary permissions on the queue manager operation.

Special note: When claiming MCA authentication under Windows and finding 2035, it may be because the channel authentication record Settings are blocked. You just need to change the list of users.

How to Fix Error 1069:The service did not start due to a logon failure

Problem: The system cannot access the Oracle database. Viewing the database server, the database cannot be logged in normally through the System account, and the error is shown as OrA-12560: TNS: Protocol Adapter Error. Check for reasons that five Oracle-related services on the server are not running.

Why are five services stopped at the same time?Click Start and the following error will be reported:

Reason: A system user oracle2012C was created when setting up the database server. The Oracle service requires system validation by this user. But this user’s password has expired, causing the service to fail to start properly.

Solution: The local System Account can be used for account verification, and the service can be started normally. You can also change the password for this account, re-enter the password and pass verification.
PS: Although Error 1069:The service did not start due to a logon failure, there are many reasons for this Error. The solution in this article is to tell the reader that even an expired password for an operating system account can cause this error.
