StackOverflow post.
I am trying to modify pip, so that after each install or uninstall, my
requirements.txt will get updated.
To do so, I have modified the pip file in the bin/ of my virtual env.
pip:
#!/Users/username/ProjectEnv/bin/python3
# -*- coding: utf-8 -*-
import re
import sys
from pip import main
if __name__ == '__main__':
sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
status = main()
if status == 0 or status is None:
sys.argv = ['pip', 'freeze', '>', '../Project/requirements.txt']
sys.exit(main())
This didn't work. I have tried printing the command line arguments and
putting a breakpoint, but they didn't work as well.
pip:
#!/Users/username/ProjectEnv/bin/python3
# -*- coding: utf-8 -*-
import re
import sys
import pdb
pdb.set_trace()
from pip import main
if __name__ == '__main__':
for arg in sys.argv:
print(arg)
sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
status = main()
if status == 0 or status is None:
sys.argv = ['pip', 'freeze', '>', '../Project/requirements.txt']
sys.exit(main())
What am I doing wrong here?
Regards
