This would be a very basic question, but please allow me to ask…

■Question
What should I do for credentials problem when pip install repository from bitbucket? I have an access to the bitbucket repository and do not know why credential problem occurs…

■What I have done on terminal
pip3 install git+{url that I get from bitbucket for cloning}

■The error message I got
Missing or invalid credentials.
fatal: Authentication failed for {url that I get from bitbucket for cloning}
exit code: 128

note: This error originates from a subprocess, and is likely not a problem with pip.
