在Windows 10 PowerShell中激活虚拟环境时出错

Question

在Windows 10 PowerShell中激活虚拟环境时出现错误：

ControllerBase.ValidationProblem

即使尝试这种方式：

PS C:\Users\sunil\Desktop\my_projects> .\venv\Scripts\activate.ps1
.\venv\Scripts\activate.ps1 : The term '.\venv\Scripts\activate.ps1' is
not recognized as the name of a cmdlet, function, script file, or operable
program. Check the spelling of the name, or if a path was included, verify
that the path is correct and try again.
