我正在遵循这个tutorial to automate the creation of release notes using the wiki in Azure DevOps。步骤非常基本，并且没有太多变量会导致错误。

当我创建一个版本时，它会运行，然后在PowerShell任务中失败。这是日志中显示的内容，并带有错误：

[错误]无法将术语“powershell.exe”识别为cmdlet、函数、脚本文件或可操作程序的名称。请检查名称的拼写，或者如果包含路径，请验证路径是否正确，然后重试。

我已将日志中的座席名称替换为 [myLocalAgent]

我在网上搜索过，由于文件名中的空格（我的文件名中没有空格）或引用的路径不正确（我的PowerShell是内联/自动生成的），因此引用了不正确的拼写。
会很感激任何帮助。
先谢谢你。
