1. Uninstall the current computer node.js

Be sure to uninstall the node in the current computer first

Especially environment variables and .npmrc files (this file is recommended to use the everything tool to find and delete this file in the user directory of the C drive )

Otherwise, the node.js installation may fail later

But if it is an environment variable that is automatically deployed during installation, you don't have to worry about environment variables and file residues

2. Download the nvm package manager

Git download address: https://github.com/coreybutler/nvm-windows/releases

Ali cloud disk download address (installation version): Ali cloud disk sharing password: 16md

It is recommended to download the installation version to automatically configure environment variables to save a lot of operations

3. Installation

1. Agree to the installation agreement

2. Select the installation location of the nvm package manager

3. Select the node installation location

After installing nvm, you will reinstall node later. This installation location is where you reinstall node.

4. In the last step, click Install

5. Check whether the installation is successful

Run cmd - enter nvm directly - check if the installation is successful The following conditions represent a successful installation

4. Configuration and use

Open the nvm installation directory to find settings.txt and open it

Since I have already installed node, there will be v14 and v16 folders

Add the following two lines of code to set the Taobao mirror source
