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

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~

The solution
First check the error log, the solution is really forgotten, really sorry……
PS: friends, really sorry, in the past for a long time, the specific solution to forget, I hope that friends, brainstorm, together to solve this problem, there is a better more detailed way, leave a message we discuss together! Thank you very much!

update
First of all, thank you for your recommendation!

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.

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.

Open anaconda to report an error

It is very likely that there is a problem with the file, and mine is the condarc file. Just change the condarc file to the correct one.The correct file content is
ssl_verify: True,
channels:

El-cascader error: Cannot read property’level’ of null

Leave a reply

After the current drop-down menu is selected, the value is assigned normally. When refreshing, there is no problem. When the data is selected, the interface of the search is requested and an error is reported directly.

 

 

 According to the error message, I clicked in and took a look, and found that cascader has the checkedValue of the selected item and the clicked parent node (highlighted) activePath. Even if it is set this.cascaderValue= [] ,

The activePath in cascader still has a value, that is, the clicked parent node will be recorded, and an error will be reported if cascader is not found when loaded again.

 

solve: 

In the recommended blog, I saw that a key is set for cascader. When the type is changed, the key value is also changed. If the key value is changed, cascader will re-render.

 

 

 

Set cascaderKey in data to 1 by default,

Then set ++this.cascaderKey in the requested interface

 When the options change Change key Value, then the component is re-rendered

Execute an error under pytest cmd make sure your test modules/packages have valid Python names.

Problem Description:

Use pytest.main([‘TestcasePairValue.py’]) to execute OK in the case code, but use pytest TestcasePairValue.py under cmd to execute the error as follows

Importing the while Test Module1 ImportError ‘D: \ code \ APITEST \ TestCase \ TestcasePairValue.py’.
Hint: the make your Test modules Sure / Packages have have Valid

I checked the online information and said that there was a circular reference, but I checked the two files and did not see where there is mutual reference. Finally, I found a solution to the big problem. Record it:

Create a new conftest.py file in the executed case file directory, and write the content:

import os
import sys
sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), '..')))

Get it done! It can be executed on the console normally!

fatal: unable to access”: The requested URL returned error: 500

Leave a reply

In the morning, I turned on the computer for research and development, and the information came, and the local git push code reported an error. Okay, take a screenshot of the error report

fatal: unable to access”: The requested URL returned error: 500

 

 

 

To be honest, if you look at this content, it is a feedback permission problem, then directly take the account password and log in to the gitlab page to try it. I took the R&D account and password to log in and it didn’t respond. And my own account login is no problem.

solve:

Log in to gitlab as an administrator user, and then reset the password of the R&D user account.

This application has no explicit mapping for /error, so you are seeing this as a fallback.

This application has no explicit mapping for /error, so you are seeing this as a fallback.

Solution:

When springboot is simply tested, the results cannot be displayed correctly. The reason is that the hierarchical structure of the directory is incorrect. The startup class should be placed in the outermost layer of all sub-packages.
