What is the NVM

📄 NVM is a node versioning tool that allows you to install multiple Node versions (and matching NPM versions) in the same environment and switch between them at any time.

Ordinary computers can only install one version of Node 😟, but in work, we may use different versions of Node in face of different projects, which caused a lot of trouble to programmers 👨💻. At this time, NVM came into being 👽

Download and install

To download NVM, go to Github

Select nvM-setup. zip to download the zip package. You need to decompress it and double-click to install it

Github was slow to download, but here I put it on the Blue Cloud, where you can download the EXE file directly

The NVM run file

The installation

Double-click to install; The installation will let you choose the path, I usually install this tool by default, all the way to the next step

It’s probably going to pop up again and again when you install it

This is because I already have Node installed, so just click ‘yes’

🤡 Check whether the installation is successful

Go to CMD and type in

nvm -v
Copy the code

If a large number is displayed and the version number is available, the installation is successful

Using the command

Displays the versions available for download

nvm list available
Copy the code

Download different versions of Node

NVM Install Version/ / such as
nvm install 11.13. 0
Copy the code

Uninstall the node version

NVM Uninstall Version numberCopy the code

You can also view the versions that have been installed, as well as the version number in use

nvm ls
Copy the code

Where the asterisk is is the version in use

🤡 Switching version NVM Use version

nvm use 14.7. 0
Copy the code

Problems in use

😫 Cannot change the version number & NPM cannot be used. This is because the node has been installed before the NVM installation, so the original node is uninstalled and deleted, and then the NVM is reinstalled. Install node in NVM

Uninstall node — > Reinstall NVM. Exe — > Download Node from NVM — > Switch to Node
