It seems the issue is our use of `pyenv global` to set the python version.

> <https://github.com/pyenv/pyenv/issues/331>

You can read more details in the github issue, but to workaround this, you need to delete `.pyenv-version` file manually before CircleCI changes python version like this.

```auto
machine:
  pre:
    - rm .python-version

  python:
    version: 3.5.1

```

Here is a working build: [https://circleci.com/gh/kimh/trusty-test/329](https://circleci.com/gh/kimh/trusty-test/329)

There are a few options to fix this permanently and I need to think a bit to decide which path we want to go. Please use the workaround until we fix the issue.

Thank you for your patience.
