安装

通过脚本安装

Node.js is not preinstalled

On POSIX systems, you may install pnpm even if you don't have Node.js installed, using the following script:

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 -

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

Node.js is preinstalled

On Linux or macOS:

curl -f https://get.pnpm.io/v6.16.js | node - add --global pnpm

在 Windows （PowerShell）上安装：

Invoke-WebRequest 'https://get.pnpm.io/v6.16.js' -UseBasicParsing -o pnpm.js; node pnpm.js add --global pnpm; Remove-Item pnpm.js

上述安装脚本是经过签名的。这里是验证方法。

Using Corepack

Since v16.13, Node.js is shipping Corepack for managing package managers. This is an experimental feature, so you need to enable it by running:

corepack enable

This will automatically install pnpm on your system. However, it probably won't be the latest version of pnpm. To upgrade it, check what is the latest pnpm version and run:

corepack prepare pnpm@6.21.1 --activate

通过 npm 安装

npm install -g pnpm

通过 npx 安装

npx pnpm add -g pnpm

升级

安装 pnpm 之后，就无需使用其它软件包管理器来更新 pnpm 了。 你可以让 pnpm 自己来更新自己，如下所示：

pnpm add -g pnpm

你是否需要在 CI 服务器上使用 pnpm？请参阅 持续集成 章节。

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
←[90m    at Function.Module._load (internal/modules/cjs/loader.js:725:27)←[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 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.

Uninstalling pnpm

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