VSCode PowerShell扩展初始化失败，无法激活Python虚拟环境求助

问题重现 #

使用Activate.ps1激活Python虚拟环境时，触发以下错误：

[Warn  - 2:20:50 pm] OmniSharp.Extensions.LanguageServer.Server.LspServerOutputFilter: Tried to send request or notification before initialization was completed and will be sent later OmniSharp.Extensions.JsonRpc.RequestCancelled | @Request='OmniSharp.Extensions.JsonRpc.RequestCancelled'
[Error - 2:21:26 pm] Connection to PowerShell Editor Services (the Extension Terminal) was closed. See below prompt to restart!

已尝试重装VSCode、清除缓存，问题未解决。

解决方案 #

• 调整PowerShell执行策略
  以管理员身份打开PowerShell，执行：

  Set-ExecutionPolicy RemoteSigned
  

  输入Y确认，允许本地脚本运行（默认策略会阻止Activate.ps1这类脚本）。

• 重置VSCode PowerShell扩展配置
  打开VSCode，按Ctrl+Shift+P打开命令面板，选择Preferences: Open Settings (JSON)，添加或修改：

  "powershell.powerShellExePath": "C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell.exe",
  "powershell.enableProfileLoading": false
  

  指定系统默认PowerShell路径，禁用用户配置文件加载，避免扩展与自定义配置冲突。

• 清理PowerShell扩展缓存
  关闭VSCode，删除以下目录：

  • %USERPROFILE%\.vscode\extensions\ms-vscode.PowerShell-*（替换*为实际版本号）
  • %USERPROFILE%\AppData\Roaming\Code\CachedData中所有与PowerShell相关的子目录
    重启VSCode，扩展会自动重建缓存。

• 绕开扩展直接激活环境
  在系统PowerShell中进入虚拟环境目录，执行：

  .\Scripts\Activate.ps1
  

  激活成功后，执行code .打开VSCode，此时编辑器会继承已激活的虚拟环境。

• 重建虚拟环境
  删除损坏的虚拟环境，重新创建：

  Remove-Item -Recurse -Force .\venv
  python -m venv venv
  .\venv\Scripts\Activate.ps1
  

  排除环境文件损坏导致的脚本执行异常。
