Con: npm itself is now also installed into ~/.npm-global (e.g.

Con: No package.json of what’s installed makes reinstalls more work.

Pro: npm install -global works everywhere.

We can now continue to install packages with the flag -global, but they won’t be installed globally, they will be installed into our home directory: npm install -global some-package Instead of that symbol, we can also use the shell variable $HOME (on Unix and Windows), but must take care that shell variables are expanded.Īfterwards, we must add ~/.npm-global to the PATH. We create a directory and set npm’s prefix to that directory: mkdir ~/.npm-globalĪ tilde ( ~) on its own refers to the home directory on Unix and Windows. npm adds links from it into the global node_modules – e.g.: /usr/local/bin/tsc ->. This directory is part of the macOS PATH by default. Second, a bin directory which contains executable files: % npm bin -global Under that prefix, there are two important subdirectories.įirst, a node_modules directory: % npm root -global

We can display the current prefix as follows (I’m showing the results for my Mac): % npm config get prefix The npm documentation recommends to change the npm prefix. On Unix, we can display it like this: echo $PATH On Windows, we can display the current PATH like this: $env:PATH There are many good tutorials online, just do a web search for: If we want to install executables via npm, it’s important that the PATH is set up correctly. This PATH is a command line variable that lists all paths where the command line looks for executables when we enter a command. In the remainder of this blog post, we need to change the command line PATH for some approaches. Preparation: changing the command line PATH #

Approach 5: using a Node.js version manager.

Approach 3: installing into a subdirectory of the home directory.

Approach 2: installing into the home directory.

Preparation: changing the command line PATH.

That’s why this blog post explores alternatives to global installs. The latter requires root access on macOS and some other Unix platforms – which is a considerable downside. (Instead of the long version -global of this flag, we can also use the shorter -g.) Globally, into a global node_modules directory: npm install -global some-package Locally, into a node_modules directory that npm searches for (or creates) in the current directory and its ancestors: npm install some-package There are two ways in which npm packages can be installed:
