Gevent: CFFI install issue

[SanderBeekhuis]

• gevent version: 1.3.2
• Python version: Please be as specific as possible: "Python 3.4.2 (virtualenv)"
• Operating System: Please be as specific as possible: "Debian GNU/Linux 8 (jessie) (Linux tc1 3.16.0-4-amd64 #1 SMP Debian 3.16.39-1+deb8u2 (2017-03-07) x86_64 GNU/Linux)"

Description:

When I'm trying to install gevent it errors out in the following way:

Requirement already satisfied: cffi in ./lib/python3.4/site-packages (from -r requirements.txt (line 8)) (1.11.5)
Collecting gevent (from -r requirements.txt (line 9))

I've reverted back to gevent 1.2.2. This works as expected.

It may be related to this change but I don't know (https://github.com/gevent/gevent/commit/14544dae9bdbc85be20ceee98c07ef7e539d0e01)

I have only limited acces to this machine for testing.

What I've run:

pip install -r requirements.txt

I think I have the same issue

• Ubuntu 14.04.5 LTS (Trusty)
• Python 2.7.6
• Gevent 1.3.2

Gevent 1.3.1 installs without issues.

Thanks for the reports. That error means that the version of setuptools installed is too old. You'll need to update it. (1.3.1 installed because there was a binary wheel available for it, but a packaging error means that 1.3.2 has to be installed from source.)

1.3.2.post0 manylinux1 wheels have been posted.
