Python error: importerror: DLL load failed: unable to find the specified module solution

Error message
The following error is reported while using Python for a dataset:

The reason for the error
The error occurs because the corresponding module’s file is incomplete or there is no corresponding module.
The solution
The solution is as follows:
The main steps are as follows:
1. Locate the module and uninstall it with PIP. Take the example I came across:

pip uninstall numpy

2. Reinstall the module again.

pip install numpy

The point is which module is causing this problem?
We read the wrong picture:

Find the most recent import package code that reported the error, regardless of importing packages from ‘. ‘:

We found out it was NumPy and reinstalled the module.
 
 

Module not found: Error: Can’t resolve ‘sass-loader’ in ‘F:\H5\project-h5’

Module not found: Error: Can’t resolve ‘sass-loader’ in ‘F:\H5\project-h5’

The error is more straightforward. Without the SASS-Loader, we just need to install the specified plug-in as required.

npm install sass-loader -D
npm install node-sass -D



The second installation will take a little longer, so be patient.
Meng New exclusive extension: -d =& GT; — Save-dev, and another -s => – save.
If the two plug-ins installed after the following error ↓

This may be a compilation error due to a high version of the SASS-Loader

npm uninstall sass-loader（Uninstall current version） 
npm install [email protected] --save-dev

Recompiling is successful

Module not found: Error: Can‘t resolve ‘sass-loader‘


there are many situations, such as not installing
SASS loader NPM install sass-loader node-sass –save-dev
or installing a version too high to support, the following is to solve the version too high

//First remove the version we have already installed.
npm uninstall node-sass 
npm uninstall sass-loader
npm uninstall style-loader
//Note that when we clean up, we can choose to clean up globally install globally, otherwise we will get the same error the next time we create the project.
npm i node-sass --sass_binary_site=https://npm.taobao.org/mirrors/node-sass/ //Taobao image installation
npm install [email protected] --save-dev //Install version 7.3.1 of sass
npm install style-loader --save-dev // install style-loader

Cannot find module ‘internal / util / types’ appears during gulp build

when I was compiling the compressed file with gulp build, which had always been easy to use before, I ran this error out of nowhere. Because it had been easy to use before, it suddenly became difficult to use, so I wondered if there was something wrong with the code. cannot find module. If you install NPM install XXXXX –save-dev, you will be able to solve the problem.

, I searched again and found that someone said that de-versioning could be solved, so I tried to reduce node’s version from v10 to V8 first, but the problem still existed, then from V8 to v6, and executed again, but found that this was the case. It depends on the version of Node. (If you want to use the latest version of Node, you need to upgrade gulp to the response version as well. You need to uninstall Gulp first and then re-install the new version of Gulp. During the process, a series of error prompts of The Cannot Find Module will appear. It is only necessary to install these missing modules once.
