Node multi-version management (clear and clear)

overview

I recently learned about the cloud project, and the front end uses technologies such as vue3 + ts. When starting the vue3 project, a higher node version (16.15.0) is required, but I don’t want to uninstall the original version. At this time, node multi-version management is required. According to the project The method provided by the official document is recorded here .

1. Install nvm

windows install nvm

1. You need to uninstall the locally installed Node.js first, and then download nvm , address:
   https://github.com/coreybutler/nvm-windows/releases

2. In general, find the latest version, and then download the nvm-setup.exe file . After downloading, we can double-click to install it.

3. We use PowerShell to open the command line. It should be noted here that PowerShell must be opened as an administrator , as follows:
   

4. Command nvm version, you can view the version number , as follows
   

linux install nvm

1. In the Linux warehouse of nvm, there are corresponding tutorials , warehouse address: https://github.com/nvm-sh/nvm
2. Installing nvm is very simple, just execute the following command

# 下载并执行安装脚本
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
# 使nvm命令生效
source ~/.bashrc

3. The nvm command on linux is somewhat different from that on windows, but the basic usage is the same . You can check the instructions on github for details, so I won’t introduce it here.

2. Install nodejs

After we have installed nvm, install Node.js through nvm , as follows:

1. To view the list of available versions of Node.js , execute the following command:

nvm ls available

2. To install Node.js with version number 16.15.0 , execute the following command:

nvm install 16.15.0

3. To view the installed version number , execute the following command:

nvm list

4. To switch the version number to 16.15.0 (specify your own version number) , you can execute the following command:

nvm use 16.15.0

5. To view the current version number of Node.js , execute the following command:

node -v

6. To uninstall Node.js whose version number is 16.15.0 (specify your own version number) , you can execute the following command:

nvm uninstall 16.15.0
