I created `.exe` file using `pyinstaller 3.3.1` and I got this message

```
Traceback (most recent call last):
File "install.py", line 14, in <module>
ImportError: No module named configobj
[8468] Failed to execute script install

```

I'm working with `python 2.7` using `conda` environment. Lately I had updated `pyinstaller` to `version 3.3.1` so this happened to me while I'm checking that the update is safe.

I have also created another `.exe` file from different script that uses also this `import` and its went well, so any help will be welcome.
