Installazione

Prerequisites

If you don't use the standalone script or @pnpm/exe to install pnpm, then you need to have Node.js (at least v18.12) to be installed on your system.

Using a standalone script

You may install pnpm even if you don't have Node.js installed, using the following scripts.

Su Windows

warning

Sometimes, Windows Defender may block our executable if you install pnpm this way.

Due to this issue, we currently recommend installing pnpm using npm or Corepack on Windows.

Using PowerShell:

Invoke-WebRequest https://get.pnpm.io/install.ps1 -UseBasicParsing | Invoke-Expression

Su sistemi POSIX

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

If you don't have curl installed, you would like to use wget:

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

tip

You may use the pnpm env command then to install Node.js.

In a Docker container

# bash
wget -qO- https://get.pnpm.io/install.sh | ENV="$HOME/.bashrc" SHELL="$(which bash)" bash -
# sh
wget -qO- https://get.pnpm.io/install.sh | ENV="$HOME/.shrc" SHELL="$(which sh)" sh -
# dash
wget -qO- https://get.pnpm.io/install.sh | ENV="$HOME/.dashrc" SHELL="$(which dash)" dash -

Installing a specific version

Prima di eseguire lo script di installazione, è possibile impostare facoltativamente una variabile env PNPM_VERSION per installare una versione specifica di pnpm:

curl -fsSL https://get.pnpm.io/install.sh | env PNPM_VERSION=<version> sh -

Using Corepack

Dalla versione 16.13, Node.js fornisce Corepack per la gestione dei gestori di pacchetti. Questa è una funzionalità sperimentale, quindi è necessario abilitarla eseguendo:

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.

Using other package managers

Using npm

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

• pnpm is an ordinary version of pnpm, which needs Node.js to run.
• @pnpm/exe is packaged with Node.js into an executable, so it may be used on a system with no Node.js installed.

npm install -g pnpm

or

npm install -g @pnpm/exe

Using Homebrew

If you have the package manager installed, you can install pnpm using the following command:

brew install pnpm

Using winget

If you have winget installed, you can install pnpm using the following command:

winget install -e --id pnpm.pnpm

Using Scoop

If you have Scoop installed, you can install pnpm using the following command:

scoop install nodejs-lts pnpm

Using Choco

If you have Chocolatey installed, you can install pnpm using the following command:

choco install pnpm

Using Volta

If you have Volta installed, you can install pnpm using the following command:

volta install pnpm

tip

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

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'
←[90m    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:880:15)←[39m

  code: ←[32m'MODULE_NOT_FOUND'←[39m,
  requireStack: []
}

First, try to find the location of pnpm by running: which pnpm. If you're on Windows, run where.exe pnpm.* 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.

Aggiunta di un alias permanente sui sistemi POSIX

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

alias pn=pnpm

Aggiunta di un alias permanente in 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.

Updating pnpm

To update pnpm, run the self-update command:

pnpm self-update

Disinstallazione di pnpm

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