Uninstalling local packages

You can remove a package from your node_modules directory using npm uninstall <package>:

npm uninstall lodash

To remove it from the dependencies in package.json, you will need to use the save flag:

npm uninstall --save lodash

Note: if you installed the package as a "devDependency" (i.e. with --save-dev) then --save won't remove it from package.json You have to use --save-dev to uninstall it.

Test:

To confirm that npm uninstall worked correctly, check to see that the node_modules directory exists, but that it does not contain a directory for the package(s) you uninstalled. You can do this by running ls node_modules on Unix systems, e.g. "OSX", "Debian", or dir node_modules on Windows.

Example:

Install a package called lodash. Confirm that it ran successfully by listing the contents of the node_modules directory and seeing a directory called lodash.

Uninstall lodash with npm uninstall. Confirm that it ran successfully by listing the contents of the node_modules directory and confirming the absence of a directory called lodash.

> npm install lodash
> ls node_modules               # use `dir` for Windows
 
#=> lodash
 
> npm uninstall lodash
> ls node_modules
 
#=>
