In some scenarios, we would like to use a specific version of npm (Node Package Manager) for the compatibility reasons. Let's explore how to install a separate version of npm

First, enter into a specific folder, for example: gww, then execute the following command in the cmd window opened inside this folder:

npm install npm@6.14.15

After the specific version has been installed, use the following command to use the specific version of npm:

npx npm -v

Optionally, we can also use:

.\node_modules\.bin\npm -v

Then we could use this specific version of npm, for example:

npx npm run serve

Or optionally we can also use:

.\node_modules\.bin\npm run serve
