移除PowerShell 7后VS2022调用其路径致MSB3073构建错误

问题根源 #

卸载PowerShell 7后，VS2022未自动更新默认Shell配置，仍尝试调用已移除的C:\Program Files\PowerShell\7\pwsh.exe，导致项目PostBuild事件执行时找不到路径，触发MSB3073构建失败错误。

解决步骤 #

1. 重置VS2022默认Shell #

• 打开VS2022，点击顶部菜单栏工具 → 选项
• 左侧导航栏展开环境 → 终端
• 右侧"默认Shell"下拉菜单选择Command Prompt或系统自带的Windows PowerShell（路径为C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe），点击确定

2. 修正项目PostBuild事件（若存在硬编码路径） #

• 右键目标项目 → 属性
• 展开生成事件 → 后期生成事件
• 将命令中的"C:\Program Files\PowerShell\7\pwsh.exe"替换为系统自带PowerShell路径："C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe"
• 点击应用 → 确定

3. 清理并重新构建 #

• 点击顶部菜单栏生成 → 清理解决方案
• 执行生成解决方案验证构建状态
