pipupgrade Skip distutils installed packages?

When I run pipupgrade to upgrade system packages, the first package that comes from my distribution (Debian) breaks the process. Pipupgrade does not skip it and continue, it instead exits, and I don't see any option to ignore such packages. Even in interactive mode, when it tries to upgrade such a package it just exits after, and I have to manually restart it and learn which packages to manually avoid.

Updating X of Y packages: pycairo
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

Try updating using pipupgrade --self and let me know if that helps!

pipupgrade upto date.

Yea, I confirmed this behavior. Very annoying when you're working with either beautifulsoup4 or numpy python packages.

root@bohyat14:~# pip list --outdated

Package	Version	Latest	Type
ConfigArgParse	0.13.0	0.15.2	sdist
decorator	4.3.0	4.4.1	wheel
distro	1.3.0	1.4.0	wheel

the sdist type will fail updating, and if pip-review could present the type info, one could at least answer "n" in interactive mode.

(later: apologies - it seems only some of them may fail to update)

Dec 29 '19 02:12 roydenyates

confirm the issue with the latest version

Jan 13 '20 17:01 metya

Released 1.6.7 with a new flag --ignore-error for this case.

$ pipupgrade --ignore-error

Will attempt to install packages and silently fail in case of any error.

Jan 16 '20 02:01 achillesrasquinha

Now it's just failed with

BrokenPipeError: [Errno 32] Broken pipe on just pipupgrade or with TypeError: can only concatenate str (not "datetime.timedelta") to str with flag --ignore-error

Jan 16 '20 15:01 metya

@metya Try rm -rf ~/.pipupgrade and try again?

Jan 16 '20 15:01 achillesrasquinha

nope. the same behaviour

Jan 16 '20 16:01 metya

Could you paste your log as follows?

$ pipupgrade --verbose

Hello,

I'm also impacted by this issue. Maybe the solution could be to pass here the option --local to pip. This could be enabled optionally and it could avoid to try to upgrade many package installed by the system.

Any updates on this issue? Am getting the following quite consistently now:

"DATE" | ERROR | Error executing command /usr/local/bin/pip install pipupgrade --no-cache --upgrade: DEPRECATION: Configuring installation scheme with distutils config files is deprecated and will no longer work in the near future.

Dear all, have you tried pipupgrade --ignore-error?
