Usually that would hint there is something wrong with the installation of command line git on that computer or with a missing PCRE library that command line git requires.  Refer to the following stackoverflow articles for suggestions and approaches:

It appears that git is missing and getting it installed on server.

I am in the process of setting up fresh 2.235.3 environment with gitlab plugin. I have imported all jobs from old environment and in the process of testing them.

Currently the installation is happening on RHEL 7 . The way through my testing I have discovered that Git package was missing, 

1. Is there any way I can find out if there is any documentation where I know what OS libraries are needed ?

2. If I install certain plugin, dependent plungin gets installed, are these plugins self sufficient to work ?, I am trying to find our what OS libraries they are dependent on ..

Thanks
