powershell报错：invalid command ‘hook‘ Invoke-Expression : Cannot bind argument to parameter ‘Command‘

powershell报错：invalid command ‘hook’ Invoke-Expression : Cannot bind argument to parameter ‘Command’ because it is an empty string.

每次启动powershell，总会有这个错误出来，没报错截图，但在StackOverflow上找到一个几乎一样的报错（无答案，后面同步到StackOverflow）：

网上几乎没答案，有人说可能是anaconda版本问题，所以直接试了一下升级（在anaconda prompt base中输入）：

conda upgrade -n base -c defaults --override-channels conda

再打开powershell(版本是5.1.22000.282)：

附（查看powershell版本）：

$PSVersionTable
