Synopsis:

The command pip install allmydata-tahoe fails because of a bug in the Nevow dependency.

Known workaround:

Install twisted first with pip. This works for me:

$ pip install twisted && pip install allmydata-tahoe

Details:

It appears related to Nevow. I'm hopping on #twisted to ask for advice.

I consider this major because I'm part of the PyPI + pip hegemony which intends to take over the (python) world. Also, check out this claim of >40,000 PyPI downloads!

I believe that, due to this Nevow commit, the bug only happens when import setuptools fails (as it will in a clean virtualenv).

[12:28] <dstufft> setuptools should always be importable when you're installing with pip (unless you hit the pip bug that uninstalls setuptools but your entire install will break then)

[12:31] <dstufft> daira1: pip is still broken with Nevow because the last release of Nevow was made in 2009 and it does not contain that commit

[12:32] <daira1> wow. okay

Replying to daira:

There may be more than one bug. I don't understand what the presence of setuptools has to do with the bug I find when running pip install nevow, which is that if setup.py imports nevow, then it will import twisted.

If twisted is not installed, then setup.py will raise an ImportError. This prevents a user from running "python ./setup.py " unless they've already installed a dependency. If this is true then I believe it would also break easy_install or any other case where setup.py is executed prior to satisfying dependencies.

I was mistaken: the Nevow commit isn't in any release yet [isn't on trunk, since the branch was never merged]and. pip depends on setuptools so that will always be present.

Nevow-0.11.1 was released a few days ago (https://github.com/twisted/nevow/blob/nevow-0.11.1/NEWS.txt), and supports install from 'pip'. I just confirmed that a simple pip install allmydata-tahoe in a clean virtualenv gets me a working tahoe binary (and tahoe debug repl can import nevow without complaint).

Closing this one out. Yay! Crediting this to the 1.11 milestone (even though it was fixed by something outside of tahoe's source tree) so we remember to mention it in the release notes.

Daira and I noticed we do not yet depend on Nevow >= 0.11.1. We're not yet sure if it's still possible to run into this problem, but it might be prudent to bump the requirement up.

I'm going to reopen this to ensure we bump the dependency version or discuss why not to do so.

Moved to #2291. The original problem is fixed just by the availability of Nevow 0.11.1.
