Getting install_pyuic5 error during PyQt5 install

Question

I have built source files for installing PyQt5 but when I executed sudo make install , after a while, it prompts this error message:

sudo make install
.
.
.
install -m 755 -p /home/bora/Desktop/PyQt-gpl-5.4.1/pyuic5 /usr/bin/
strip /usr/bin/pyuic5
strip:/usr/bin/pyuic5: File format not recognized
make: [install_pyuic5] Error 1 (ignored)

How can I fix this problem? I am using Qt 5.4.1 and I am sure that I have properly set the path to Qt5's qmake . If I didn't, it would gave me an error during compilation of source files. Do I need to install any dependecy for PyQt5 another than SIP?

I incurred in the same problem after following this link: https://michalcodes4life.wordpress.com/2014/03/16/pyqt5-python-3-3-in-virtualenv-on-ubuntu/ , I managed to narrow the errors down to the one you're reporting.

Notice in the link where it mentions to run configure.py with the -verbose flag:

python configure.py -verbose --qmake /path/to/Qt/5.2.1/gcc_64/bin/qmake --sip-incdir=/usr/include/python3.3m

Go through the stacktrace and see if the error you reported is the only one. If that is so then ignore it as it's just a "warning" in Python parlance. In your command line enter:

import sip
import PyQt5

should give no errors.

It's not really an error, so you can safely ignore it (just as make did).

The output is coming from the strip command, which is mainly used for removing debugging symbols from binaries. However, /usr/bin/pyuic5 is a shell-script rather than a binary, and so strip cannot process that file. As a consequence, it outputs a warning message and returns a non-zero exit status. The make process sees this, but has been configured to ignore it, and so there is no fatal error.
