exec: "pwsh": executable file not found in %PATH% - gitlab-ci

Question

I've been trying to initiate my pipeline on gitlab CI/CD for a demo project. I've installed gitlab-runner in my windows local machine and gave the executor type as "Shell". And I've successfully integrated the gitlab-runner with my gitlab project. But whenever I pushed any changes to repo, the pipeline started and end up in "pshw" not found in %PATH error.
This is error which I'm getting every time
ERROR: Job failed (system failure): prepare environment: failed to start process: exec: "pwsh": executable file not found in %PATH%. Check https://docs.gitlab.com/runner/shells/index.html#shell-profile-loading for more information
Can anyone help me to resolve this issue and explain what and why I'm getting this error.
Thanks in advance

Answer 1

When choosing the shell option, the gitlab runner installer uses pwsh as the executor. It generates a config.toml that looks like
[[runners]]
name = "some name"
url = "http://someurl.com/"
token = "some-token"
executor = "shell"
shell = "pwsh"
The problem is that pwsh isn't a valid windows command (on my installs). Changing pwsh to powershell and restarting gitlab-runner service fixed the problem for me.

Answer 2

Go to the installation directory of GitLab Runner e.g. C:\Automation\GitLab-Runner. Here you will see config.toml file, open with notepad and replace "pwsh" with "powershell" as below:
From:
[[runners]]
name = "PT-Runner"
url = "https://gitlab.com"
executor = "shell"
shell = **"pwsh"**
To:
[[runners]]
name = "PT-Runner"
url = "https://gitlab.com"
executor = "shell"
shell = **"powershell"**
