Install Python 3.7+ on CentOS 7

This was my first time to install a recent version of Python on a CentOS. I always use Ubuntu and It is pretty easy using deadlysnakes PPA. so the only way was to compile the source code from python.org website.

The how-to is on the internet but I’m writing this as I did compilation serveral times as some options weren’t set properaly. so let’s go

1. Install build tools sudo yum install gcc openssl-devel bzip2-devel libffi-devel
2. Download the source from https://www.python.org/downloads/source/
3. Extract the source
4. run ./configure --enable-optimizations --enable-shared
5. run make altinstall

Notes:

• libffi is crucial, so don’t forget it.
• --enable-shared is required if you will compile any library with C Extension.
• pip will be installed by default.
• If you get /usr/local/bin/python3.7: error while loading shared libraries: libpython3.7m.so.1.0: cannot open shared object file: No such file or directory, then do the following
• export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib or
• sudo ldconfig /usr/local/lib
