安装
前言
如果您不使用独立脚本或 @pnpm/exe 来安装 pnpm，那么您需要在您的系统上安装 Node.js(至少 v16.14)。
使用独立脚本安装
即使没有安装 Node.js，也可以使用以下脚本安装 pnpm。
Windows
使用 PowerShell：
iwr https://get.pnpm.io/install.ps1 -useb | iex
在 POSIX 系统上
curl -fsSL https://get.pnpm.io/install.sh | sh -
如果您没有安装 curl，也可以使用 wget：
wget -qO- https://get.pnpm.io/install.sh | sh -
在 Alpine Linux 上
# 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 -
安装特定版本
在运行安装脚本之前，您可以选择设置环境变量 PNPM_VERSION 来安装特定版本的 pnpm：
curl -fsSL https://get.pnpm.io/install.sh | env PNPM_VERSION=<version> sh -
然后您可以使用 pnpm env 命令来安装 Node.js。
使用 Corepack 安装
从 v16.13 开始，Node.js 发布了 Corepack 来管理包管理器。 这是一项实验性功能，因此您需要通过运行如下脚本来启用它：
corepack enable
如果您使用 Homebrew 安装 Node.js，则需要单独安装 corepack：
brew install corepack
这将自动在您的系统上安装 pnpm。 但是，它可能不是最新版本的 pnpm。 若要升级，请检查 最新的 pnpm 版本 并运行：
corepack prepare pnpm@<version> --activate
使用 Node.js v16.17 或更高版本，您只需指定标签即可安装 最新 版本的 pnpm：
corepack prepare pnpm@latest --activate
使用 npm 安装
我们提供了两个 pnpm CLI 包， pnpm 和 @pnpm/exe。
npm install -g pnpm
或者
npm install -g @pnpm/exe
使用 HomeBrew 安装
如果安装了包管理器HomeBrew，则可以使用以下命令安装 pnpm：
brew install pnpm
Using winget
If you have winget installed, you can install pnpm using the following command:
winget install 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
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 5 | pnpm 6 | pnpm 7 | pnpm 8 |
|---|---|---|---|---|
| Node.js 12 | ✔️ | ✔️ | ❌ | ❌ |
| Node.js 14 | ✔️ | ✔️ | ✔️ | ❌ |
| Node.js 16 | 未知 | ✔️ | ✔️ | ✔️ |
| Node.js 18 | 未知 | ✔️ | ✔️ | ✔️ |
| Node.js 20 | 未知 | ? | ✔️ | ✔️ |
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 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.
在 POSIX 系统上添加永久别名
Just put the following line to your .bashrc, .zshrc, or config.fish:
alias pn=pnpm
在 Powershell (Windows) 中添加永久别名：
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.
卸载 pnpm
If you need to remove the pnpm CLI from your system and any files it has written to your disk, see Uninstalling pnpm.
