Hi Mr(s) Versions, Your "locate" output shows that you have a manual installation of Python 3.4 on /usr/local, and it's possible that "/usr/local/bin" is ahead of "/usr/bin" in your PATH, which is why pip3 installs into Python 3.4.
>From your error message with Python 3.5, it seems like your Python 3.5 is a "System Python", i.e., a Python that was installed with the package manager for your system, but that your Python development packages wasn't installed yet. If yours is a Debian style system, you might need to install the "python-dev" or perhaps a "python3.5-dev" package. E.g.: - apt-get install python-dev If your system is Redhat based (Fedora, RHEL (do we already have python3.5 in any RHEL release?)), then you're looking for a "python-devel" or "python3.5-devel" package. Something like: - yum install python-dev Hope it helps.
