Pyinstaller error: OSError: Python library not found: libpython3.4mu.so.1.0, libpython3.4m.so.1.0, libpython3.4.so.1.0
I am using Python 3.4.4 on Centos7.
I have created a python program on my local machine that uses qt modules. The program works fine on my local computer. Now I am trying to create an executable using pyinstaller. I am using the command:
pyinstaller main.py
I am 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 problem is? Just say I have python3-devel and python-devel installed (relative to the sentence at the end of the printed output). Thanks to

You have to install python-dev for your python version
, eg:
Debian / Ubuntu - Python 2.7 ---> python2.7-dev
CentOs / RedHat - Python 3.4 ---> python34-devel
CentOs / RedHat - Python 2.7 ---> python27-devel
However, one of these errors can be confusing: IOError ("Python library not found!") PyInstaller needs to link the Python library, which is the main part of the Python interpreter, linked as a dynamic loading library. The name and location of this file depends on the platform you are using. Some Python installations do not include the default Python dynamic library (static-linked may be present, but cannot be used). You may need to install a development package. Or the library may exist but is not in the folder where PyInstaller is looking.
The places where PyInstaller looks for the python library differ on different operating systems, but / lib and / usr / lib are checked on most systems. If you can't put the python library there, try setting the correct path in the LD_LIBRARY_PATH environment variable on Linux or DYLD_LIBRARY_PATH on OS X.
