My python-program creates a pdf-File (via MikTeX) which is then opened with Okular. The python file works perfectly. However, when I create the binary file (via pyinstaller: pyinstaller -F file.py) on ubuntu (18.04.3), when opening the PDF in Okular it creates the following error message:

"Unable to find the Okular component: The shared library was not found" (see picture)

Any suggestions what I did wrong?

Thx for your help!

(binaries on Windows and Mac work perfectly) enter image description here

I just had a similar error. In spite of the very little detail you provided about your case, I have the feeling that it could be a similar issue as in my case.

In my case, okular was not able to find its component and generator libraries, because my environment was not correctly setup. I managed to resolve it by adding the following to my environment: 

export PATH=/usr/local/bin:$PATH

# LD_LIBRARY_PATH only needed if you are building without rpath
# export LD_LIBRARY_PATH=/usr/local/lib/x86_64-linux-gnu:$LD_LIBRARY_PATH

export XDG_DATA_DIRS=/usr/local/share:${XDG_DATA_DIRS:-/usr/local/share/:/usr/share/}
export XDG_CONFIG_DIRS=/usr/local/etc/xdg:${XDG_CONFIG_DIRS:-/etc/xdg}

export QT_PLUGIN_PATH=/usr/local/lib/x86_64-linux-gnu/plugins:$QT_PLUGIN_PATH
export QML2_IMPORT_PATH=/usr/local/lib/x86_64-linux-gnu/qml:$QML2_IMPORT_PATH

(I found this in a file prefix.sh from directory of my okular sources. Note, that I am running a custom compiled version. Of course you may have to adapt the paths. In case your okular is usually running normally, you should be able to get the correct configuration by comparing your usual shell environment with the one inside your script.)
