Is that possible to disable interactive shell (tty)? Because ‘pip’ command if works in interactive mode shows progress bars that in CircleCI look that (every update is in new line, so it produce too much output):

What command are you running that you are getting progress bars from?

I use pip install -q -r requirements.txt and it it works well,

https://circleci.com/gh/drazisil/p2pool/237 is an example.

3

I get this too. You asked what command - the default one that CircleCI infers.

if [ -e requirements.txt ]; then pip install -r requirements.txt;else pip install -r requirements.pip;fi

4

A quick hack for those who don’t want to use -q as it removes a lot of helpful debugging info…

pip -Ur requirements.txt | tee

pip will see that sys.stdout is not a TTY and not show the progress bar!

5

However, tee will not bail out on an error. (tee always returns regardless of what the pipe exits with)

6

Any solution for this issue?

pip -r requirements.txt | cat && test ${PIPESTATUS} -eq 0
