I searched the Internet but didn’t find a solution, so I had to go to the official website to find a solution:

https://answers.launchpad.net/mydumper/+faq/349

Run:
 cmake .
 make

One needs to install development versions of required libaries (MySQL, GLib, ZLib, PCRE):
NOTE: you must use the correspondent mysql devel package.

* Ubuntu or Debian: apt-get install libglib2.0-dev libmysqlclient15-dev zlib1g-dev libpcre3-dev libssl-dev
* Fedora, RedHat and CentOS: yum install glib2-devel mysql-devel zlib-devel pcre-devel openssl-devel
* openSUSE: zypper install glib2-devel libmysqlclient-devel pcre-devel zlib-devel
* MacOSX: port install glib2 mysql5 pcre pkgconfig cmake
 (You may want to run 'port select mysql mysql5' afterwards)

One has to make sure, that pkg-config, mysql_config, pcre-config are all in $PATH

Binlog dump is disabled by default to compile with it you need to add -DWITH_BINLOG=ON to cmake options

Obviously you need compiler and make packages too :)

You can see that you need to install dependencies:

Fedora, RedHat and CentOS: yum install glib2-devel mysql-devel zlib-devel pcre-devel openssl-devel

So follow the instructions to install:

[root@localhost mydumper-0.6.2]# yum install glib2-devel mysql-devel zlib-devel pcre-devel openssl-devel

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:

Error installing ODBC driver MySQL ODBC5.3 ANSI
Driver,ODBC error 13:Unable to load MySQL ODBC5.3 ANSI Driver ODBC driver
Installation routine, because there is a system error code 126: ... \Myodbc5S.dll) cannot find the specified module.

Solutions:
Solution 1: general online solution: install Microsoft Visual C++ 2013 Redistributable Package above. Verification results: Installing mysql-Connector-ODBC still prompts for the same error message after the following three versions are installed on the machine.

Microsoft Visual C++ 2015 Redistributable Package
Microsoft Visual C++ 2013 Redistributable Package
Microsoft Visual C++ 2010 Redistributable Package

Solution 2: Replace the lower version of mysql-Connector-ODBC. 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.

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

ERROR 1714. THE OLDER VERSION OF BIOVIA LICENSE PACK 2020 CANNOT BE REMOVED. CONTACT YOUR TECHNICAL SUPPORT GROUP.

The following error appears during the installation of MS2020, as shown in the following figure:

After clicking OK, the installation is complete! Finally, it can run normally under the test. I don’t know why Error 1714 is caused. Please record it for the time being. Anyone who knows it can leave a comment, thank you!

Error in PostgreSQL installation of win10

problem

The installation of PostgreSQL in win10 reports an error. The 10, 11 and 12 versions downloaded from the official website are not available. The error is as follows

there has been an error. Error running icacls
"c:\Users\abdo\AppData\Local\Temp/postgresql_installer_b4be1776ca"/T/Q/grant: Access is denied


How to fix
install this version https://get.enterprisedb.com/postgresql/postgresql-11.2-1-windows-x64.exe

Python installation of third-party libraries reported an error: “these packages do not match the hashes from the requirements file.”

Problem: an error “these packages do not match the hashes from the requirements file” appears when installing the third-party library

Reason: the download error is usually caused by the network speed problem, resulting in the corresponding hash value does not match.

Solution: when pip is needed, add the “- upgrade” parameter. Usually, the download will report an error timeout at this time, so adding a “- default timeout = 100000” is more secure (the value of timeout can vary according to the situation).

pip install --upgrade --default-timeout=100000 packagename

Later, when installing pyqt5, I encountered the same problem. I still reported an error by using the above method. After using the online method, I solved the problem

# Install pyqt5
pip install PyQt5 -i https://pypi.douban.com/simple
# Install pyqt5-tools
pip install PyQt5-tools -i http://pypi.douban.com/simple --trusted-host=pypi.douban.com

Yaml Install ERROR: Cannot uninstall ‘PyYAML’.

Error: cannot install pyyaml.

Article Directory:

1.Error cause analysis II. Final error solution

1.Error analysis

1. Start installing
I started installing yaml </ code>, using the following command:

pip install yaml

It is installed correctly and can be imported correctly from the command line, and then an error is reported when executing the program: attributeerror: module 'yaml' has no attribute 'fullloader' </ code> then I checked the version of yaml I installed:

pip show yaml   # show is version 3.12, which is too old

2. Error exploration1
check the tutorial online and say that you want to update the yaml version to 5.2 . The update method is as follows:

pip install -U PyYAML

In the process of updating, an error was reported:

ERROR: Cannot uninstall 'PyYAML'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

And then continue to find out how to solve this problem. Most of the solutions given are: delete all the yaml files under site packages , and guess what, LZ has been deleted completely. As a result, it is still this by when installing. Are you angry or not!

3. Error exploration 2

But I had to go to pypi website to download the wheel, and then install it directly

PyYAML-5.2-cp27-cp27m-win_ amd64.whlPyYAML-5.2-cp27-cp27m-win32.whl

Then install the wheels directly:

pip install PyYAML-5.2-cp27-cp27m-win_amd64.whl
# Then it said the platform is not supported, I looked at the amd may not be supported, so I tried again 32

pip install PyYAML-5.2-cp27-cp27m-win32.whl
# Again, the platform is not supported, I'm speechless

it seems that exploration is a failure. Let's find another way!

2、 Final error resolution

Use the following installation method to solve the problem:

# it worked
pip install --ignore-installed PyYAML

Another one, I don’t test it. You can try it

pip install  --force-reinstall PyYAML

or

pip install docker-py --ignore-installed PyYAML
