Missing required dependencies when using pyinstaller

[dmag]

Actual code is huge, but minimal program below reproduces error:

import pandas
import numpy
import setuptools

print pandas.__version__;
print numpy.__version__;
print setuptools.__version__;

C:\Users\DerekR>python pandastest.py
0.24.1
1.16.2
19.2


C:\Users\DerekR>dist\pandastest\pandastest.exe
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "c:\python27\Lib\site-packages\PyInstaller\loader\pyi_importers.py", line 270, in load_module
exec(bytecode, module.__dict__)
File "C:\Users\DerekR\build\pandastest\out00-PYZ.pyz\pandas", line 19, in <module>
ImportError: Missing required dependencies ['numpy']

It's python 2.7 if that's relevant
