无法在Windows上安装纱线
我有Windows 10：
$ node -v
v16.14.0
$ npm -v
8.3.1
我在终端运行，
$ npm install yarn -g
changed 1 package, and audited 2 packages in 666ms
found 0 vulnerabilities
但没有安装纱线，
$ yarn
C:\Users\G023911\AppData\Roaming\npm/node_modules/node/bin/node: line 1: This: command not found
我找不到任何有用的东西，可以说明为什么它对我不起作用。

but Yarn is not installed
$ yarn

I can't find anything helpful that shows why it is not working for me.

您只应该这样做：
corepack enable enable// elses if node.js＆lt; 16.10（yarn 1.0）：npm安装 - 全球纱YARN的终端内部检查安装， - version，如果您拥有NPM，它肯定可以工作（我已经在Windows和Linux上安装了很多次，并且它在官方1.0 doc 和官方2.0+ doc ！You should only do that :
corepack enable// else if Node.js <16.10 (yarn 1.0) :npm install --global yarnyarn --versionbut if you have npm it will works for sure (I have installed it many times on Windows and Linux this way & it's on the official 1.0 doc and official 2.0+ doc !就我而言，我从官方github存储库中的下载文件中安装了纱线

在旧开放时启动新的，这是行不通的。关闭当前代码编辑器和终端，启动新的编辑器，检查纱线 - version
In my case I installed yarn from the download file in the official github repo
https://github.com/yarnpkg/yarn/releases/download/v1.22.4/yarn-1.22.4.msi (check for a newer version)
Then I had to CLOSE code editor and terminal. Starting new tab wasn't enough, I had to close them and open new ones.
Starting new ones while the old are open didn't work. Close the current code editor and terminal, start new ones, check yarn --version
我的同样问题，这意味着您的机器上安装了纱线，但纱线的可执行文件目录不在系统的路径中。
按照下面的步骤操作：
检查纱线安装目录：
NPM bin -g添加YARN的安装目录（从上一步生成
path/to/your/your/your/your/your/your/your/your/your/bin）到系统路径linux/macOS：
添加
导出路径=“ path：/path/to/yarn/bin”到
〜/.bashrc或〜/.zshhrc或〜/.bash_profileWindows：
控制面板＆gt;系统＆GT;高级系统设置＆gt;环境变量
编辑路径变量可包括目录（
path/to/your/your/your/your/your/bin）。重新启动终端或命令提示或git bash
验证纱线安装
纱线 - Version那些解决了我的问题的人
same issue with mine, that means yarn is installed on your machine but yarn's executable directory is not in system's PATH.
follow steps below:
check yarn installation directory:
npm bin -gadd yarn's installation directory (generated from previous step
path/to/your/yarn/bin) to system pathLinux/MacOS:
Add
export PATH="PATH:/path/to/yarn/bin"to
~/.bashrcor~/.zshhrcor~/.bash_profileWindows:
Control Panel > System > Advanced system settings > Environment variables
Edit PATH variable to include the directory (
path/to/your/yarn/bin).Restart Terminal or Command Prompt or Git Bash
Verify yarn Installation
yarn --versionthose solved my problem
