Try installing the libraries with pip install --force-reinstall <package_ name> or pip install --ignore-installed <package_name>.

Keep in mind that --force-reinstall will forcefully reinstall every package and --ignore-install will ignore current installation and install over it, if the package name changes you might have 2 instances of the same package. See more details here

The error looks like you don’t have python development packages.
I assume you’re on Ubuntu. try installing the following the packages

sudo apt-get install python-dev # for python2.x installs
sudo apt-get install python3-dev # for python3.x

And then try running the above mentioned command.

Most of the time these are dependency-issues. You need to install a package called python-dev. This package includes header files, a static library and development tools for building Python modules, extending the Python interpreter or embedding Python in applications. When encountering this error please note before the error it may say you are missing a package or header file — you should find those and install them and verify if it works

For Python 2.x use:

$ sudo apt-get install python-dev

If you using python3, try to replace python-dev with python3-dev

For a specific version of Python 3, replace x with the minor version in

$ sudo apt-get install python3.x-dev
