Windows Command Prompt support broken

[WillieRuemmele]

Hello, with this PR https://github.com/sindresorhus/open/pull/188 all of the command prompt users were broken. Is there a way this library could try to open with powershell and then, if that fails, revert to opening with command prompt?

[sindresorhus]

How is it broken?

[WillieRuemmele]

we, the sfdx-cli have users who CANNOT install powershell on their computers and when they try to use one of our commands that relies on this library, their command blows up with open spawn UNKNOWN.. It seems like the linked PR above was when it was changed - I'm hoping to keep the current behavior but have it fall back to cmd if it fails

I'm not sure if that PR is the cause, but I can attest this update broke things.
Had a few dozen people report this issue to me.

Managed to grab the following screenshot:
Unfortunately I do not have more information. For now I'm downgrading.

[BillyHams]

I'm in the same situation. Access to Powershell is blocked by Group Policies for me and all my teammates. We are not 100% clear on how to downgrade easily.

Hello together, are there any news about this issue? I have here the same issue on Windows 10 Pro (Version: 1809 / OS build: 17763.1397), and with my user I don't have access to PowerShell.

I have received the following message from the SFDX CLI command, that might help?

I know, that it's an issue within sfdx-cli, but as @WillieRuemmele already said, it seems to be related here.

Thank you :)

PS: I have also created an issue for the SFDX developers.

[DebuggingYou]

Hello together, I can confirm, that my issue is solved by enabling PowerShell on my PC. After my admins have given me access to it, the error did not appear anymore :) Thank you @BillyHams for the hint!

[oliverfoster]

It would be nice to have the option to not use powershell or to define a default terminal. This issue has cropped up for me in a number of bits of software from a variety of users inside corporate networks who's access to powershell has been revoked.

[tabarra]

@oliverfoster consider downgrading to v7.1.0, it works without powershell.

[oliverfoster]

Thanks for that. I'm looking for a long term solution.

I face the same issue and able to solve it by process.env.SYSTEMROOT = process.env.SystemRoot
