The reason for installing NVM is that when adding react-redux when using React, it reminds me of a node version problem, so I plan to install a Node version management tool
because I installed Node on my computer a long time ago. , when installing NVM, it prompted me whether to overwrite and manage the existing local version. After I selected Yes
, the installation was successful.

Notes on installing NVM

1. If you modify the installation path, you must add nodejs

npm_mirror:npm.taobao.org/mirrors/npm/

Note: root and path must be placed under the same disk during installation, otherwise there will be problems with the subsequent Install

Executed the following command to check the local version

Switch to the specified Node

is not too much trouble, directly to the solution

solution

Uninstall Node

Press the win key directly, search and delete (or uninstall),
Delete after searching for node
Go to the C drive to find the remaining files
a. The default is C:\Program Files\nodejs, or it may be in other drives, depending on the choice during installation.
b. Find out whether the **.npmrc** file exists, and delete it if it exists (the default is C:\User\username.)
c. Check the file
```
C:\Program Files (x86)\Nodejs
C:\Program Files\Nodejs
C:\Users\用户名\AppData\Roaming\npm
C:\Users\用户名\AppData\Roaming\npm-cache
```
d. cmd command node -v

Finally switch directly in Windows PowerShell

nvm use 版本号

After switching, node -v will find that node already exists and the version switching is successful.
