I'm using Python 3.4.4 on Centos7.

I've created a python program on my local machine that makes use of qt modules. The program is running fine on my local machine. I'm now trying to create an executable with pyinstaller. I'm using the command:

pyinstaller main.py

I'm getting the following output:

This would mean your Python installation doesn't come with proper library files.
This usually happens by missing development package, or unsuitable build parameters of Python installation.

* On Debian/Ubuntu, you would need to install Python development packages
  * apt-get install python3-dev
  * apt-get install python-dev
* If you're building Python by yourself, please rebuild your Python with `--enable-shared` (or, `--enable-framework` on Darwin)

Does anyone know what the issue could be? Just to say I have python3-devel and python-devel installed (in relation to the suggestion at the end of the printed output.) Thanks

for Linux system like your CentOS, try rebuild python to generated shared lib using:

env PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 3.4.4

as said in pyenv offical doc
