npm command fails

After upgrading the npm command separately on the mac system, the npm command cannot be used because the node version is too low and has not been upgraded in advance:

ERROR: npm v9.6.2 is known not to run on Node.js v10.15.1. You'll need to upgrade

to a newer Node.js version in order to use this version of npm. This version of

npm supports the following node versions: `^14.17.0 || ^16.13.0 || >=18.0.0`. You

can find the latest version at https://nodejs.org/.

ERROR:

/usr/local/lib/node_modules/npm/lib/utils/exit-handler.js:21

  const hasLoadedNpm = npm?.config.loaded

 This problem of not being able to use a higher version of npm because the node version is relatively low, the usual solution:

1. View the current version

node -v

2. Clear   the cache of Node.js

sudo npm cache clean -f

 3. Use npm to install the n module, here I use the Node.js multi-version manager n to upgrade

sudo npm -gn

4. View all versions of node

npm view node versions

5. Upgrade the version, here I chose to upgrade to a stable version

sudo n latest. //upgrade the latest version

sudo n stable //upgrade stable version

sudo n XX.XX. //Upgrade to the specified version

6. View version

node -v //View the latest version after upgrade

In this process, because the npm command has expired and cannot be used, step 3 cannot be executed successfully. At this time, you can use Homebrew of mac to achieve: brew install n

 After successful execution, you can view the version number: n --version

Other:

 There is an error prompt at the end of the n command installation, Error: Permission denied @ apply2files - /usr/local/lib/docker/cli-plugins

Can be executed by: sudo chown -R $(whoami) $(brew --prefix)/*

Another method (untested):

mkdir -p /Applications/Docker.app/Contents/Resources/cli-plugins
brew cleanup

 Additional commands:

1. Node version downgrade/upgrade (install specified node version)

sudo n 版本号  // 例如：sudo n 10.16.0

2. Uninstall the specified node version

sudo n rm 版本号

3. Detect which node versions are currently installed

n

4. Switch node version (other versions installed will not be deleted)

sudo n 版本号

5. Update npm to the latest version

sudo npm install npm@latest -g

6.cnpm install lower version

npm install -g [email protected] --registry=https://registry.npm.taobao.org
