安装 Cordova 和 ionic 的问题

Question

为什么无法安装 Cordova... 它说 power shell 无法识别。这是什么意思？我该如何解决？我尝试了一些基本命令，例如 改变我的道路 系统变量 > 路径 > C:\Users\me\AppData\Local\Android\Sdk\platform-tools

npm install -g cordova-res
npm install -g ionic cordova-res
npm install cordova-res-generator -g

cordova-res-generator
rror: Command failed: powershell (Get-CimInstance -ClassName Win32_OperatingSystem).caption
'powershell' is not recognized as an internal or external command,

欢迎！

我不是 Windows 用户，但您的 PATH 中似乎没有 powershell cmd。

将此添加到您的系统环境中：

%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\
