Installation

Prérequis

Si vous n'utilisez pas le script autonome ou @pnpm/exe pour installer pnpm, vous devez avoir Node.js (au moins v16.14) d'installé sur votre système.

En utilisant un script autonome

Vous pouvez installer pnpm même si vous n'avez pas installé Node.js, en utilisant les scripts suivants.

Sur Windows

En utilisant PowerShell:

iwr https://get.pnpm.io/install.ps1 -useb | iex

POSIX :

curl -fsSL https://get.pnpm.io/install.sh | sh -

Si vous n'avez pas installé curl, vous pouvez utiliser wget:

wget -qO- https://get.pnpm.io/install.sh | sh -

astuce

Vous pouvez ensuite utiliser la commande pnpm env pour installer Node.js.

En utilisant Corepack

Depuis la v16.13, Node.js propose Corepack pour gérer les gestionnaires de paquets. Il s'agit d'une fonctionnalité expérimentale, vous devez donc l'activer en exécutant :

info

If you have installed Node.js with pnpm env Corepack won't be installed on your system, you will need to install it separately. See #4029.

corepack enable pnpm

If you installed Node.js using Homebrew, you'll need to install corepack separately:

brew install corepack

This will automatically install pnpm on your system.

You can pin the version of pnpm used on your project using the following command:

corepack use pnpm@latest

This will add a "packageManager" field in your local package.json which will instruct Corepack to always use a specific version on that project. This can be useful if you want reproducability, as all developers who are using Corepack will use the same version as you. When a new version of pnpm is released, you can re-run the above command.

En utilisant npm

We provide two packages of pnpm CLI, pnpm and @pnpm/exe.

• pnpm est une version ordinaire de pnpm, nécessitant Node.js pour fonctionner.
• @pnpm/exe est livré avec Node.js dans un exécutable, il peut donc être utilisé sur un système sans Node.js installé.

npm install -g pnpm

or

npm install -g @pnpm/exe

astuce

Do you wanna use pnpm on CI servers? See: Continuous Integration.

Compatibility

Here is a list of past pnpm versions with respective Node.js version support.

Node.js	pnpm 7	pnpm 8	pnpm 9
Node.js 12	❌	❌	❌
Node.js 14	✔️	❌	❌
Node.js 16	✔️	✔️	❌
Node.js 18	✔️	✔️	✔️
Node.js 20	✔️	✔️	✔️

Troubleshooting

If pnpm is broken and you cannot fix it by reinstalling, you might need to remove it manually from the PATH.

Let's assume you have the following error when running pnpm install:

C:\src>pnpm install
internal/modules/cjs/loader.js:883
  throw err;
  ^



Error: Cannot find module 'C:\Users\Bence\AppData\Roaming\npm\pnpm-global\4\node_modules\pnpm\bin\pnpm.js'

}

First, try to find the location of pnpm by running: which pnpm. If you're on Windows, run this command in Git Bash. You'll get the location of the pnpm command, for instance:

$ which pnpm
/c/Program Files/nodejs/pnpm

Now that you know where the pnpm CLI is, open that directory and remove any pnpm-related files (pnpm.cmd, pnpx.cmd, pnpm, etc). Once done, install pnpm again and it should work as expected.

Using a shorter alias

pnpm might be hard to type, so you may use a shorter alias like pn instead.

Ajout d'un alias permanent sur les systèmes POSIX

Just put the following line to your .bashrc, .zshrc, or config.fish:

alias pn=pnpm

Ajout d'un alias permanent dans Powershell (Windows):

In a Powershell window with admin rights, execute:

notepad $profile.AllUsersAllHosts

In the profile.ps1 file that opens, put:

set-alias -name pn -value pnpm

Save the file and close the window. You may need to close any open Powershell window in order for the alias to take effect.

Désinstaller pnpm

If you need to remove the pnpm CLI from your system and any files it has written to your disk, see Uninstalling pnpm.
