Seems this style requirement is not supported.

See https://www.python.org/dev/peps/pep-0508/ for full requirement grammar.

Thanks @jsbain I re-wrote pip in a rush and simplified and even missed many things. Thanks for the information. I didn't even know it exist.

[jsbain]

A new issue... The issue was line 293 of the pycrypto setup.py

    sub_commands = [ ('build_configure', has_configure) ] + build_ext.sub_commands

since build_ext.sub_commands was a stub, so could not be added to a list.

Changing pip.py line 67 to

class OmniClass(list):

it allows this type of usage. Not sure if there are other side effects.'

[ywangd]

I just manually added the sub_commands attribute (an empty list) to the faked build_ext modules. This should fix this particular case. I guess we'll have to wait and see if there are more exceptions to come.

[jsbain]

did pip ever support version numbers on the commandline? This seems to be broken in dev right now.
pip install pyte 0.4.2 for example.

A short term fix might be an update to ssh, which uses this to install pyte, instead using simply pip install pyte.

[ywangd]

@jsbain I don't really remember which revision removed the version argument. But I guess it makes sense since the version specifier is the more correct way to do it. So I just updated the usage in ssh and telnet to pip install pyte==0.4.10. 9ce995ff5ec02189b31317cf735a0341f608b2e7

It appears that you are running stash in py3.  I would recommend still using py2 to run stash (for git at least)On Feb 5, 2019 7:51 AM, Jeremiah Helfer [email protected] wrote:Unable to install anything with pip, each time it comes back with:: Querying PyPI ...
