NAME
npm-removal - Cleaning the Slate
SYNOPSIS
So sad to see you go.
sudo npm uninstall npm -g
Or, if that fails, get the npm source code, and do:
sudo make uninstall
More Severe Uninstalling
Usually, the above instructions are sufficient. That will remove npm, but leave behind anything you´ve
installed.
If that doesn´t work, or if you require more drastic measures, continue reading.
Note that this is only necessary for globally-installed packages. Local installs are completely contained
within a project´s node_modules folder. Delete that folder, and everything is gone (unless a package´s
install script is particularly ill-behaved).
This assumes that you installed node and npm in the default place. If you configured node with a
different --prefix, or installed npm with a different prefix setting, then adjust the paths accordingly,
replacing /usr/local with your install prefix.
To remove everything npm-related manually:
rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/npm*
If you installed things with npm, then your best bet is to uninstall them with npm first, and then
install them again once you have a proper install. This can help find any symlinks that are lying around:
ls -laF /usr/local/{lib/node{,/.npm},bin,share/man} | grep npm
Prior to version 0.3, npm used shim files for executables and node modules. To track those down, you can
do the following:
find /usr/local/{lib/node,bin} -exec grep -l npm \{\} \; ;
(This is also in the README file.)
