pyinstaller ImportError: No module named pkg_resources

Question

I am trying to package up my Python script using Pyinstaller. My script imports the third party modules Exscript and Netaddr. I get the error below when I try to run the executable generated by Pyinstaller.

I know "pkg_resources" refers to setuptools, but I checked and I have setuptools 18.2 under site-packages and I see easy install in the scripts directory. I'm running Python 2.7.

Any help with getting Pyinstaller to work is appreciated. FYI, I did search and review similar questions here and they did not apply to this particular problem.

Here is the output from running Pyinstaller(I only included the errors):

C:\Python27\Lib\PyInstaller-2.1>pyinstaller c:\users\<username>\pycharmprojects\neworking2\network_login.py
5759 INFO: building because out00-Tree.toc missing or bad

9569 INFO: rebuilding out00-PKG.toc because out00-PKG.pkg is missing
9591 INFO: rebuilding out00-EXE.toc because network_login.exe missing

The output of executing the .exe generated by Pyinstaller:

Answer 1

Just import it as:

import pkg_resources.py2_warn

In the main file.

Answer 2

When my script import a module apscheduler, I met a similar error:

Traceback (most recent call last):
...
    File "d:\Anaconda\lib\site-packages\apscheduler\schedulers\base.py", line 9, in <module>
      from pkg_resources import iter_entry_points
ImportError: No module named pkg_resources
scheduler2 returned -1

It seems that pyinstaller can not extract the content from setuptools*.egg that you installed.

My workaround is to manually extract setuptools*.egg from python lib directory (PYTHON_INSTALL_PATH\lib\site-packages\setuptools*.egg) to the same directory of the problem script, and run pyinstaller again.

In my environment, copy D:\Anaconda\lib\site-packages\setuptools-18.4-py2.7.egg to the same directory of my py script, rename it to setuptools-18.4-py2.7.zip, and extract the content (don't create new direcotry setuptools-18.4-py2.7) to the same dir of my py script.
