Node version switching management using NVM

When I was developing a project, I was confused by the version of node, because different projects use different versions of node. Some projects can also be installed in a high-version node environment, but most projects areIt can only run under a specific node version, so switching node versions frequently is a headache.

Here the official provides us with NVM, which, as the name suggests, is a version management tool for nodejs.Through it, you can install and switch between different versions of nodejs.

Use of NVM

One, installation

git: github.com/coreybutler…

• nvm-noinstall.zip: Green free installation version, but needs to be configured when using.
• nvm-setup.zip: The installation version, it is recommended to use it. Similar to the next step, you can choose the nvm installation path and node installation path by yourself. Note that the installation path should not have Chinese and spaces.
• After the installation is complete Enter nvm to check whether the installation is successful

Second, install/manage nodejs

1. View all versions installed locally; there is an optional parameter available, which displays all downloadable versions.

nvm list [available]

2. Install the specified node version. The version number in the command can be customized. For details, refer to the list queried by command 1
