How to install global module permissions using npm

This time I will show you how to use npmInstallationglobal module permissions, what are the precautionsfor using npm to install global module permissions, the following is a practical case, let's take a look .

There are three ways to solve this problem:

Permission to modify the global installation path

Modify the default installation path

Use third-party tools to install node

Permission to modify the installation path

View the default global installation path

npm config get prefix

Displayed for most systems The directory is: /usr/local

Warning: If the default path is in /usr/ please skip this step, otherwise you will mess up system permissions.

Modify path permissions

sudo chown -R (whoami)(whoami)(npm config get prefix)/{lib/node_modules,bin,share}

After execution, the ownership of lib/node_modules, bin, and share under /usr/local will be changed to the current user.

Modify the default global installation path

When you do not want to modify the permissions of the default installation path, because this may cause some additional problems, for example, after modifying the permissions It cannot be shared with other users of the current system. At this time, you can consider modifying the default installation path.

In the example, I changed the default global installation path to the current user’s home directory:

1. Create a new one Global installation path

mkdir ~/.npm-global

2. Configure npm to use the new path

npm config set prefix ‘~/.npm-global'

3. Open or create a new ~/.profile and add the following One line

export PATH=~/.npm-global/bin:$PATH

4, UpdateSystem environmentVariables

source ~/.profile

Try to install a global package:

npm install -g jshint
[luncher@localhost aaa]$ ls ~/.npm-global/bin/
jshint
[luncher@localhost aaa]$

Use third-party tools to install node

Mac system uses brew to install node

brew install node

centos uses yum tool to install node

yum install node
