How to fix 'Missing required dependencies ['numpy']' when running packaged app made with PyInstaller?

问题

When I run my packaged app I get the error ImportError: Missing required dependencies ['numpy']. How do I fix this?

The full error:

I used pyinstaller guiMain.py to create the .exe, within a virtual environment created with pipenv shell. This virtual environment has numpy 1.16.0 installed, aswell as pandas, pyinstaller, sklearn, googleads and pytest.

When I run the code (unpackaged and within the virtual environment) everything works fine. The packaging process goes fine aswell, until I try to run the .exe, which gives the error above.

So far I have tried:

• uninstalling and installing numpy and pandas multiple times without success.
• removing virtual environment and creating a new one and installing all required packages, without success.

I thought the error might have been caused by the recent update to the googleads package (which caused an error with pyyaml version mismatch when locking the pipfile.lock), but downgrading this package to 15.0.1 didn't resolve the numpy issue (it did resolve the pyyaml issue).

My Pipfile:

[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true

[dev-packages]

[packages]
numpy = "*"
pandas = "*"
sklearn = "*"
pyinstaller = "*"
pytest = "*"
googleads = "==15.0.1"

[requires]
python_version = "3.6"

Any help is appreciated.

Apparrently the newest version of numpy (v1.16.0) breaks something in pyinstaller, because packaging the app with numpy version 1.15.4 works fine.
