PyInstaller找不到PyYAML隐藏的导入

Question

I am using PyInstaller to freeze a script that depends on PyYAML .

I was getting the following error:

ImportError: No module named 'yaml'

So I included yaml as a hidden import, but PyInstaller can't import it.

$ pyinstaller myapp.spec
...
2515 DEBUG: Hidden import: yaml
2516 INFO: Analyzing hidden import 'yaml'
2516 ERROR: Hidden import 'yaml' not found
...

So running my binary still fails with the same error.

PyYAML is installed on the active virtual environment, as other modules that don't fail when included on hidden imports. I've also tried to install it globally and even to install the python-yaml system package (Debian).

What am I doing wrong?

Answer 1

I've solved it installing the python3-yaml system package. My mistake was to install the Python2 version.
