Receiving the following error when pushing commitments to Github in R: error: cannot run rpostback-askpass: No such file or directory fatal:

Question

I want to push some changes to my GitHub repository and I receive the following error, which I have been trying to solve for the last couple of hours.

error: cannot run rpostback-askpass: No such file or directory
fatal: could not read Username for 'https://github.com': Device not configured

What I have just done is

• Open a new repository on Github
• Go to code and copy the https link
• Go to R Studio > New Project > Version Control > Git
• Paste the https link to repository URL
• Write some code and save it to an R file
• Select the file > Commit > and Push

and I receive this error, which I was not getting previously. (Note that I took a long break and during this time I have not committed anything to Github but previously, I have not face any error like that.)

I have searched some solution on the internet, while some suggested to use SSH key instead of https, I could not find a neat solution (that might be because I am not familiar with the Github workflow)

Therefore, I would appreciate if you can just provide me a clean solution on how to solve this problem. Thank you for your attention beforehand.

PS: I am using a Mac if that would matter.

This should be linked to the lack of credential helper which means Git is trying to read credentials from your terminal, since it exhausted other options.

Check your git config --global credential.helper first.

Try and install GCM, the Git Credential Manager (which is no longer GCM-core).
And reference it in your config:

git config credential.helper manager
