That's because of how poetry2nix defines bootstrapped-pip.

also python 2.7 is EOL and the only maintenance we do is reducing it.

How then to use nixops?

How then to use nixops?

There is nixops_unstable.

There is nixops_unstable.

Tried. Some features don't work in unstable version :(

[Ma27]

Let's face the unfortunate truth, nixops is basically dead these days, so I'd rather find out how to move away from it.

Package python2Packages.bootstrapped-pip tries to use default package python3Packages.wheel, and package python2Packages.wheel is required.

Is it possible to add such a fix, or is another way required?
