How to upgrade Vue version

Question

I was using the Vue version (2.5), I ran that command npm install -g @vue/cli after that I check my vue version by using the command vue --versionand it shows me @vue/cli 4.1.2. but in my package.json file the version did not upgrade, it still showing me the older version i.e 2.5.7.

Any help would be highly appreciable

Solution 1

npm install -g @vue/cli --save

--save will automatically update version in your package.json file.

Solution 2

You can upgrade it through vue cli.

npm install -g @vue/cli

OR

yarn global add @vue/cli

then

vue upgrade

Solution 3

Both provided answers assume you have a project and you're updating it. If you want to update the global installation, as per the documentation in the Vue website at https://cli.vuejs.org/guide/installation.html you need to do the following:

npm update -g @vue/cli
