pyinstaller executable can't find package info

The pyinstaller complains the error with the following line:

from gcloud.pubsub.client import Client

The module is installed correctly in /usr/local/lib/python2.7/dist-packages. I run setup.py (build/ install) in addition pip install --upgrade cloud too.

You will need to create a pyinstaller hook for packages that depend on setuptools’ get_distribution() to obtain metadata information about the package.

Create a hook file in some hooks directory. The file name should be hook-<modulename>.py for pyinstaller to find it properly (i.e. hook-gcloud.py).

The content will be:

from PyInstaller.utils.hooks import copy_metadata
datas = copy_metadata('google-cloud-core')

The hooks directory should be set in the Analysis phase of your pyinstaller .spec file:

a = Analysis(['bogus.py'],
             pathex=[],
             binaries=[],
             hiddenimports=[],
             hookspath="/path/to/your/hooks/dir",
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher)

I haven’t tested the above, but this is what worked for me for another python package which is doing something similar (APScheduler).

If and when you get this working, consider contributing the hook back to pyinstaller project.

In the root folder of bogus.py two directories (build, dist) are created after executing

$ pyinstaller bogus.py

execute the binary by

$ cd /dist/bogus && ./bogus

and the said error should pop up.

I updated to google-cloud as instructed, the problem persists:

As @mtwu-aviatrix commented on Oct 29, 2015, the native interpreter has no problem with this import. The problem arises when it has been bundled by Pyinstaller (ver. 3.2).
