インストール

前提条件

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.

スタンドアロンスクリプトを使用する

Node.js がインストールされていない場合でも、次のスクリプトを使用して pnpm をインストールできます。

Windows の場合

PowerShell を使用:

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

POSIX システムの場合

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

curlがインストールされていない場合は、wgetを使用します。

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

ヒント

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 -

特定のバージョンのインストール

Prior to running the install script, you may optionally set an env variable PNPM_VERSION to install a specific version of pnpm:

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

Corepack を使用する

Since v16.13, Node.js is shipping Corepack for managing package managers. これは実験的な機能であるため、次のコマンドを実行して有効にする必要があります。

情報

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

Homebrew を使用して Node.js をインストールした場合は、Corepack を個別にインストールする必要があります。

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.

npm を使用する

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

• pnpm is a 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

Homebrew を使用する

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

brew install pnpm

wingetを使用する

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

winget install pnpm

Scoop を使用する

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

scoop install nodejs-lts pnpm

Chocoの使用

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

choco install pnpm

Voltaを使用する

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

volta install pnpm

ヒント

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

トラブルシューティング

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

}

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.

短いエイリアスを使用する

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

POSIX システムでの永続的なエイリアスの追加

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

alias pn=pnpm

Powershell (Windows) に永続的なエイリアスを追加

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.

pnpmをアンインストールする

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