“PowerShell”未被识别为内部或外部命令

Question

I have just installed Chocolatey via PowerShell, I tried running PowerShell both as myself and as administrator, and if I try running choco or cinst I get the following error:

PS C:\> choco /?
'PowerShell' is not recognized as an internal or external command,
operable program or batch file.

What do I do? I have a feeling this is related to more than just Chocolatey...

Answer 1

This can happen if a program is not on your PATH. Open a PowerShell prompt and enter

[environment]::setEnvironmentVariable('PATH',
"$env:path;C:\Windows\System32\WindowsPowerShell\v1.0", 'm')

then restart PowerShell.

I found this helpful.

• Write cmd in the start menu, right-click and run as administrator.
• Then in the cmd, paste in this to install choco

@powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((new-object net.webclient).DownloadString(' https://chocolatey.org/install.ps1 '))" && SET PATH=%PATH%;%ALLUSERSPROFILE%\\chocolatey\\bin

Put Chocolatey on the path.

Edit the system environmental variable. Go to

System Properties → Advanced → Environment Variables → System variables → PATH → Edit → New

Look for where Chocolatey is. In my case it was at C:\\ProgramData\\chocolatey . Enter that, don't forget to put "\\" after Chocolatey. Ie, it should be: C:\\ProgramData\\chocolatey\\
