Upgrade NPM and node under Linux

NPM Upgrade

Don't say much nonsense, just talk about the steps. Start with the easy first and upgrade NPM.

NPM This package management tool has been criticized by people, many people recommend the use of yarn, but its number of users are still not reduced, and NPM are installed with node at the same time, let me abandon it, or a bit difficult to do.

npm i -g npm

Yes, you've read it right. Upgrading NPM is just like installing a different package, which can be upgraded under Windows and Linux, and you can also specify the version of NPM.

npm i -g [email protected]5.0.0

Node upgrade

Node escalation is a bit more complicated than NPM.

1, first install node's version management tool through NPM "n", do not be surprised, the name is so simple, called N. It is understood that N is a module under node, and the author is the developer of the Express framework.

npm i -g n

• 1

2. Check N module

Check the installation path of the system node first, and the default path for the N module is '/usr/local '.

$ which node/data/home/server/nodejs/bin/node   #举个例子

If the path is the same as the default path of the N module, you can skip 3 steps.

3. Modify the default node installation path for n through the N_prefix variable.

(1) Editing the Environment configuration file

vim ~/.bash_profile

(2) Insert the following two lines of code at the end of the file

export N_PREFIX=/data/home/server/nodejs #node实际安装位置export PATH=$N_PREFIX/bin:$PATH

(3): Wq save exit;

Executes the source to make the modification effective.

(4) Confirm that the environment variable is in effect.
