Building a Python project using Pants on Bitbucket Pipelines

[kf Fellows]

I'm currently attempting to build a Python project using Pants. However, when I try to create my PEX files, I get the following error:

 **** Failed to install apache-beam-2.2.0 (caused by: NonZeroExit("received exit code 1 during execution of `[u'/usr/bin/python2.7', '-', 'bdist_wheel', '--dist-dir=/tmp/tmpnnAmyB']` while trying to execute `[u'/usr/bin/python2.7', '-', 'bdist_wheel', '--dist-dir=/tmp/tmpnnAmyB']`",)):

I have tried to replicate the issue by following the "Debug your pipelines locally with Docker" article, but everything works fine; it's only when I'm trying to use Bitbucket Pipelines that I get this error message.

Here are the contents of my `bitbucket-pipelines.yml`, as well:

image: python:2.7

pipelines:
 branches:
  staging:
    - step:
      name: Create PEX files for all tasks
      script:
        - pip install pantsbuild.pants==1.3.0
        - for dir in src/python/*/; do pants binary ${dir}tasks::; done
      artifacts:
        - dist/*

Any insight into how I can debug?

Hey,

it looks like pip is not installed. 

Could you run `sudo easy_install pip` or if you are using python 2.6 `sudo easy_install_2.6 pip` ?
