The power shell cannot use basic commands

Question

The power shell cannot use basic commands

布布子 21

System: windows11

When I execute a command in powershell, I cannot use it;
For example, 'ping','java','nodejs'

I can execute it correctly in CMD.
I'm sure it's already added to the 'path' variable.

But it still won't execute in powershell.
Display 'ping is not recognized as an internal or external command'

It worked a long time ago,I'm not sure what configuration I changed.
I tried to reinstall powershell, but it didn't work.

Hey @布布子

It sounds like you may need to update the PATH variable

Go to Properties in My computer, Advanced system settings → Advanced → Environment Variables Select 'PATH' from the list of system variables and edit and set PATH to c:\windows\system32 ; this will solve your problem

Otherwise, I would recommend uninstalling and re-installing PowerShell.

Control Panel > Uninstall a program > Turn Windows features on or off > fine Windows Powershell and uncheck. Restart your PC and follow the same process to re-install.

I'm sure my ‘PATH’ variable is fine.
In 'Turn Windows features on or off', I turned off powershell2.0.
After restarting the computer, powershell still exists on the system

It comes from “C:\Windows\System32\WindowsPowerShell\v1.0”.
I tried to delete it and found it couldn't be deleted :(.

I tried using "winget install --id Microsoft.Powershell --source winget" to update, but it didn't work

Open a Powershell prompt and run this command.

($env:path).split(";")

It should look like. The first 4 Windows folders need to be there.

$env:PATHEXT where.exe ping where.exe ping.exe ping.exe -n 1 127.0.0.1 ping -n 1 127.0.0.1

In the end, 'ping' couldn't find the command.

Thank you very much!
With your help, I tried to add the PATHEXT variable and make it equal to ".exe"
Finally, it is found that the command can be executed.
Thank you very much.

Pathext should contain these entries.

PS C:\> $env:PATHEXT .COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC;.CPL

Hello,

Indeed it may look like a wrong environmental variable. Try the next:

1.Search for "environment variables" in the Windows search bar and open the respective Control Panel item.
2.A System Properties window will appear. Click on "Environment Variables" at the bottom.
3.Edit the PATH environment variable and add the path to the folder where where the sources are located is located. (for example for Ping, should be C:/Windows/System32
