'Install NPM into home directory with distribution nodejs package (Ubuntu)

I'd like to use the distribution Node.js packages (or the chris-lea ppa for more recent releases) but install NPM to my home directory.

This may seem picky, but it's a pretty idiomatic way for polyglot/github-using developers to setup language runtime/library environments under Linux: distro packages for the runtime, 3rd-party libraries in per-user environment (see virtualenv, RVM - RVM will also build Ruby for you if you want). If necessary I will build node locally but it's a PITA since Node is becoming an incidental development requirement for lots of projects.

Instructions for installing node+npm to home directory

node.js npm

Solution 1:^[1]

Jake's answer was posted in 2012 and while useful it references Chris Lea's Node.js PPAs who are no longer updated since march 2015.

Here's the steps I use to install Node.js and npm in my home directory:

Install Node.js with nvm (no `sudo` required):

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh | bash
source ~/.bashrc
nvm install 7
npm install -g npm  # update npm

Now you can install -g without sudo and everything goes into ~/.nvm/

Or install Node.js without nvm (official instructions):

Install Node.js

Node.js v6 (current LTS as of May 2017):

curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
sudo apt-get install -y nodejs

Node.js v7:

curl -sL https://deb.nodesource.com/setup_7.x | sudo -E bash -
sudo apt-get install -y nodejs

Change npm's default directory to a local one:

mkdir ~/.npm-global
npm config set prefix '~/.npm-global'
export PATH="$HOME/.npm-global/bin:$PATH"  # ? put this line in .bashrc
source ~/.bashrc  # if you only updated .bashrc

Alternatively replace .npm-global by the directory of your choice.

Update npm and check it is installed in your `$HOME` directory:

$ npm install npm -g
/home/<username>/.npm-global/bin/npm -> /home/<username>/.npm-global/lib/node_modules/npm/bin/npm-cli.js
/home/<username>/.npm-global/lib
??? [email protected] 
  ??? [email protected] 
  ? ??? [email protected] 
  ??? [email protected] 
  ??? [email protected]

Now you can install -g without sudo and without messing with your system files.

The solution posted by Just Jake is great. However, due to a bug with npm > 1.4.10, it may not work as expected. (See this and this)

While the bug is solved, you can downgrade to npm 1.4.10 by following this steps:

Comment the prefix line in your $HOME/.npmrc
Run sudo npm install -g [email protected]
Ensure that the right version of npm is installed (npm --version)
Uncomment the prefix line in your $HOME/.npmrc
Proceed to install your global packages in your home folder!.

Because python does already a great job virtualenv, I use nodeenv. Compared to nvm, you can create multiple environments for the same node version (e.g. two environments for node 0.10 but with different sets of packages).

ENVNAME=dev1

#  create an environment
python -m virtualenv ${ENVNAME}

# switch to the newly created env
source ${ENVNAME}/bin/activate

# install nodeenv
pip install nodeenv

# install system's node into virtualenv
nodeenv --node=system --python-virtualenv

The readme is pretty good: https://github.com/ekalinin/nodeenv

I used @just-jake solution for some time and found that nvm is easier to setup. Also it's much powerful solution that allows to install and use different versions of nodejs.

On Ubuntu 14.04 or 16.04:

Install prerequisite packages for building nodejs:

sudo apt-get update
sudo apt-get install build-essential libssl-dev

Install nvm:
```
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.1/install.sh | bash
```
In case newer version of nvm will be available you can find actual installation command on nvm site.
nvm installer will add bootstrap script to ~/.bashrc, so you need either to reopen terminal to run it, or to do:
```
source ~/.bashrc
```

Now you can install any nodejs version you like, switch between them etc.

Use nvm ls-remote to list available nodejs versions.

To install, for example, nodejs v4.2.4 do:

# install v4.2.4
nvm install v4.2.4 
# use nodejs v4.2.4 in the current terminal session
nvm use v4.2.4
# use v4.2.4 by default in new terminal session
nvm alias default v4.2.4

Solution 5:^[5]

As stated already here and here

npm config set prefix ~
echo export PATH=\$PATH:\~/bin >> ~/.bashrc
. ~/.bashrc

Solution 6:^[6]

Other answers have outdated solutions: 2020's solution is using NPM_CONFIG_PREFIX environment variable. (See details)

For example,

$ NPM_CONFIG_PREFIX="$HOME/.npm-packages" npm install -g ios-sim
/Users/<name>/.npm-packages/bin/ios-sim -> /Users/<name>/.npm-packages/lib/node_modules/ios-sim/bin/ios-sim
+ [email protected]
added 108 packages from 68 contributors in 3.094s

To expand on the answer provided by Just Jake and user1533401: I am unable to downgrade as I use shared hosting and node is installed in a system directory. This is also why I have change the directory where npm installs global scripts if I want it to do that. For those in the same boat, here is a another temporary fix I found works:

npm install -g --prefix=$(npm config get prefix) <package>

The bug is that npm doesn't read your per-user config file, but specifying it every time you install a global script fixes that. Found here.

Solution 8:^[8]

I have a slightly different solution to a similar problem, which was due to my installing npm globally so I can use it in the Terminal of my macOS system. I simply initialised it locally at the root directory of my repository with the command:

npm init --yes

This did the trick for enabling me to install node packages in the local root directory at /node_modules with the "package.json" and "package-lock.json" files instead of at the user's home directory.

Solution 9:^[9]

At least on Ubuntu the default config for system wide npm is that npm install --global tries to install packages to /usr/lib/node_modules. To set different default for your own user account run following once:

mkdir -p ~/.npm/lib/bin
npm config set prefix "~/.npm/lib"

in addition you want following fragment in .profile:

# set PATH so it includes user's private .npm/lib/bin if it exists
if [ -d "$HOME/.npm/lib/bin" ] ; then
    PATH="$HOME/.npm/lib/bin:$PATH"
fi

If you now install something with npm install --global packagename it will end up in correct location and can be found in your PATH (you may need to logout and re-login for .profile changes to take effect).

Of course, you could select some other directory instead. For example ~/.config/npm could make sense for modern systems.

Solution 10:^[10]

You can use npm-user to automatically set up npm to install packages into your user's directories instead of the system's. No root privileges needed.

Here's a link to the script, instructions on how to use it and information about its options. It works on macOS, Linux, *BSD and Windows.

You can run it like so:

$ curl -s "https://raw.githubusercontent.com/alexdelorenzo/npm-user/main/npm-user.sh" | bash

After you run it, using npm install -g <package> will install packages to your user's directories without needing to use sudo.

Here's the code if you want to copy and paste it into your console:

#!/usr/bin/env bash
# Copyright 2022 Alex DeLorenzo <alexdelorenzo.dev>. Licensed under the GPLv3.
export ROOT="${1:-$HOME}"

export NPM_DIR=".npm-packages"
export NPM_ROOT="$ROOT/$NPM_DIR"

export NPM_MAN="$NPM_ROOT/share/man"

export BASH_RC="$HOME/.bashrc"
export ZSH_RC="$HOME/.zshrc"
export DEFAULT_RC="$BASH_RC"

export RC_ERR=1
export INDENT=2

set -e

shopt -s expand_aliases

alias indent="paste /dev/null - | expand -$INDENT"


quiet() {

}


expand-tilde() {
  local path="$1" 
  echo "${path/#\~/$HOME}"
}


create-paths() {
  local bin="${1:-$NPM_BIN}"
  local man="${2:-$NPM_MAN}"

  mkdir --parents --verbose "$bin" "$man"
}


set-prefix() {
  npm config set prefix "$NPM_ROOT"
}


get-vars() {
  local bin="${1:-$NPM_BIN}"
  local man="${2:-$NPM_MAN}"

  cat <<EOF
export PATH="\$PATH:$bin"
export MANPATH="\${MANPATH:-\$(manpath)}:$man"
export NPM_PACKAGES="$NPM_ROOT"

}


already-added() {
  local rc="${1:-$DEFAULT_RC}"
  local bin="${2:-$NPM_BIN}"
  local man="${2:-$NPM_MAN}"

  local vars="$(get-vars "$bin" "$man")"
  quiet grep "$vars" "$rc"
}


main() {
  local rc="$(expand-tilde "${1:-$DEFAULT_RC}")"
  local bin="$(expand-tilde "${2:-$NPM_BIN}")"
  local man="$(expand-tilde "${3:-$NPM_MAN}")"

  printf "Creating %s and %s\n" "$bin" "$man"
  create-paths "$bin" "$man" || {
    printf "Couldn't create paths: %s and %s.\n" "$bin" "$man" 
    return $RC_ERR
  }
  
  printf "Setting npm prefix.\n"
  set-prefix || {
    printf "Couldn't set prefix.\n"  
    return $RC_ERR
  }

  if ! already-added "$rc" "$bin" "$man"; then
    printf "Writing to %s.\n" "$rc"
    get-vars "$bin" "$man" >> "$rc"
 
  fi || {
    printf "Unable to write to %s.\n" "$rc"
    printf "Add the following to your shell's configuration file:\n\n"

    get-vars "$bin" "$man" | indent
    return $RC_ERR
  }

  printf "Done.\n\n"
  printf "To load the changes in this shell, run:\n"
  printf "\tsource %s\n" "$rc"
}
