Hi, thank you for reporting the issue. In case you have not done so, please install the current version of pypi2nix from master on your machine and try again. Many improvements have been made. You can install the current master version of pypi2nix on your machine via

nix-env -if https://github.com/nix-community/pypi2nix/tarball/master

I'm getting a different error about a missing dependency now (argh). There might not be anything y'all can do about this since the dependency, flit, seems to require Python 3. I wonder how pypi2nix was getting past this step before, though:

Give this a try with master version, it might work.

pypi2nix -v -V 2.7 -E libffi -E openssl -r requirements.txt -s flit

But no guarantees

Okay, it looks to me as if ptyprocess wants to use flit which is not available for python 2 :( I went and checked the source code of ptyprocess and the latest version not requiring flit seems to be 0.5. The I tried the following:

[nix-shell:~/src/pypi2nix/testing]$ pypi2nix -e ptyprocess==0.5 -V 2.7

Which seemed to work. So adding ptyprocess==0.5 to your requirements file might work to solve this specific problem.

It completed successfully, thank you. 🙂
