Corepack 和 Yarn 问题 -yarn init -2 因请求错误而失败

Question

问题

如何在 Windows 10 下修复此问题

• 为纱线 v1.22.22 运行

  C:\>yarn exec env

  最初返回

  error Couldn't find the binary env

  ，现在返回

  error Couldn't find the binary env

• 运行

  yarn install

  失败并显示

  Request Error: at ClientRequest.<anonymous> 

我尝试过的事情

纱线安装说明指出要运行

corepack enable

C:\>corepack enable
C:\>corepack -v
0.23.0

这似乎有效。下一步是运行

yarn init -2

但这已经失败了

C:\dev\yarn_test>yarn init -2
Internal Error: ENOENT: no such file or directory, 
                stat '%userprofile%\AppData\Local\node\corepack\yarn\4.2.1'
Error: ENOENT: no such file or directory, 
               stat '%userprofile%\AppData\Local\node\corepack\yarn\4.2.1'

              yarn@stable init -2 --install=self
Directory: C:\dev\yarn_test

运行

dir %userprofile%\AppData\Local\node\corepack\yarn\

显示没有4.*目录。

可以快速查看Corepack是否启用 通过运行

yarn exec env

：如果你得到一个路径作为输出， Corepack 已正确安装。如果没有，可能会出现问题 以及垫片的安装方式。在这种情况下，请检查故障排除 建议部分。

运行

yarn exec env

失败，并显示

C:\>yarn exec env
yarn exec v1.22.22
error Couldn't find the binary env
info Visit https://yarnpkg.com/en/docs/cli/exec for documentation about this command.

使用 npm 安装 corepack

下一个建议是以管理员身份运行后运行

npm install -g corepack

，corepack版本已升级到

corepack -v   0.28.0

现在再次运行

yarn init -2

似乎可以工作

! Corepack is about to download https://repo.yarnpkg.com/4.1.1/packages/yarnpkg-cli/bin/yarn.js
? Do you want to continue? [Y/n] Y`
...

但它因请求错误而失败

    at internalConnectMultiple (node:net:1114:18)
    at afterConnectMultiple (node:net:1667:5)

运行

yarn check

似乎工作正常 - 它返回：

yarn check v1.22.22
success Folder in sync.
Done in 0.09s.

克隆示例并尝试安装它

我的盒子使用公司反向代理。连接到互联网需要像这样的用户名和密码

http://<user>:<pass>@<our-proxy>.foo.bar:port

并存储在环境变量

echo %HTTP_PROXY%

中。但这已经为 npm 设置了（尽管我的电脑也有 npm 问题）

成功克隆此示例项目后

git clone https://github.com/salesforce/utam-js-recipes.git

运行

C:\dev\utam\utam-js-recipes>yarn install

再次失败并显示

C:\dev\utam\utam-js-recipes>yarn install

将代理添加到配置中

我不确定是否需要此步骤，因为我已经有代理的环境变量，但我确实运行了

yarn config set httpProxy http://<user>:<pass>@<our-proxy>.foo.bar:PORT
yarn config set strict-ssl false

Answer 1

是的，需要添加 Yarn 4.x 的代理设置（httpProxy 和 httpsProxy）。

yarn config set httpProxy http://<user>:<pass>@<your-proxy>.foo.bar:PORT
yarn config set httpsProxy http://<user>:<pass>@<your-proxy>.foo.bar:PORT
