安装@vue/cli后，出现"Vue: command not found"的错误提示。

Question

我不知道为什么这对我不起作用。我以管理员身份打开powershell并运行npm install -g @vue/cli。我已经卸载了vue-cli，重新安装也不起作用。以下是我的错误信息：

PS C:\WINDOWS\system32> npm install -g @vue/cli

Answer 3

在Windows系统中：

第一步：在环境变量中添加 %path%;%appdata%\npm;C:\Program Files\nodejs;C:\Users\User.npm-global;C:\Program Files (x86)\bin\

第二步：https://classic.yarnpkg.com/en/docs/install/#windows-stable 安装 yarn 或 npm

第三步：以管理员身份运行 Windows shell

执行 set-executionpolicy unrestricted 命令

第四步：运行 yarn global add @vue/cli 命令

结果：

C:\Users\User>vue --version @vue/cli 4.5.15
