[testtomat]

Affected tool:
pip install oletool

Describe the bug
Can not install oletool offline, because installation process tries to load dependent files from internet

File/Malware sample to reproduce the bug

How To Reproduce the bug
1.) Download https://github.com/decalage2/oletools/releases/download/v0.60.1/oletools-0.60.1.zip
2.) run pip3.xx.exe install -U "<path_to_oletools>\oletools-0.60.1.zip" WITHOUT active internet connection

Expected behavior
under offline installation I don't expect to have an active internet connection

Console output / Screenshots

pip3.10.exe install -U "<path_to_oletools>\oletools-0.60.1.zip"

Indeed a normal pip installation will not work offline, because it needs to download a number of dependencies (listed in requirements.txt and setup.py).
To install offline, you need to get every dependency first, and then install them one by one in the correct order, with oletools at the end. This would need to be added to the documentation.

Okay, thanks.

Is this the only way or is it possible to make a Copy 'n Paste deployment of all installed packages from a development machine to a production machine?
Sorry, I'm a C#-developer and not familar with Python environment.

In theory yes, you could copy the site-packages directory where Python stores all external packages, assuming you have the same python version on both machines.
But you need to pay attention how external packages have been installed in the first place:

• if packages were installed as root/administrator, they should be in the global site-packages directory of the python interpreter. (this is the easiest solution but not recommended on modern Linux distributions)
• if they were installed as a non-admin user, they may be in a site-packages directory in the user's profile.
• and they can also be installed in a virtual environment, which is located in a dedicated directory to avoid dependency conflicts with the system.

But all in all, I would recommend to download all dependencies locally and install them with pip (with a script, to automate things). It's probably a bit more work, but it would avoid any install glitches.
