Answer by Rodmentou for Npm install cannot find module 'semver'

Just remove the /node_modules folder and try again. ;)

You can use npm rm to remove it.

You can also check this issue on GitHub. To be more specific about unnistal, try to follow this:

Uninstalling

So sad to see you go.

sudo npm uninstall npm -g Or, if that fails,

sudo make uninstall More Severe Uninstalling

Usually, the above instructions are sufficient. That will remove npm, but leave behind anything you've installed.

If you would like to remove all the packages that you have installed, then you can use the npm ls command to find them, and then npm rm to remove them.

To remove cruft left behind by npm 0.x, you can use the included clean-old.sh script file. You can run it conveniently like this:

npm explore npm -g -- sh scripts/clean-old.sh npm uses two configuration files, one for per-user configs, and another for global (every-user) configs. You can view them by doing:

npm config get userconfig # defaults to ~/.npmrc npm config get globalconfig # defaults to /usr/local/etc/npmrc Uninstalling npm does not remove configuration files by default. You must remove them yourself manually if you want them gone. Note that this means that future npm installs will not remember the settings that you have chosen.
