安装.NET及Power Apps CLI后执行pac pcf init命令报错求助

我按照微软教程创建首个Power Apps组件框架（PCF）组件，已安装.NET SDK 8.0.203、.NET Runtime 8.0.3，全局安装了Power Apps CLI，但运行以下命令时：
pac pcf init --namespace SampleNamespace --name LinearInputControl --template field --run-npm-install

出现错误：

You must install .NET to run this application.

PATH已包含路径：

:/Users/xyz/dotnet:/Users/xyz/.dotnet/tools

解决建议 #

• 修正DOTNET_ROOT环境变量：从dotnet --info可见，实际.NET安装路径为/usr/local/share/dotnet，但当前DOTNET_ROOT指向/Users/xyz/dotnet，路径不匹配导致pac无法找到.NET。执行以下命令临时修正（重启终端后生效）：

  export DOTNET_ROOT=/usr/local/share/dotnet
  

  若需永久生效，编辑~/.zshrc或~/.bash_profile（根据使用的Shell类型），添加上述export命令后执行source ~/.zshrc（或对应配置文件）。

• 重新安装Power Apps CLI：先卸载现有pac工具，再重新安装，确保工具与当前.NET环境正确关联：

  dotnet tool uninstall -g Microsoft.PowerApps.CLI.Tool
  dotnet tool install -g Microsoft.PowerApps.CLI.Tool
  

• 调整PATH优先级：确保/usr/local/share/dotnet在PATH中，且优先级高于其他可能的.NET路径。执行echo $PATH检查，若未包含则添加：

  export PATH="/usr/local/share/dotnet:$PATH"
  

  同样可写入Shell配置文件实现永久生效。

• 验证架构匹配：确认pac工具与.NET均为x64架构（当前环境已显示一致，此步可快速排除架构不兼容问题）。
