Fedora 25 and fix python modules.

This tutorial is a simple way to fix your python modules under Fedora distro.
I used Fedora 25 and python 2.7.13 version.
First try to use this command:

pip freeze --local | grep -v '^\-e' | cut -d = -f 1  | xargs -n1 pip install -U

This command will try to update based by:

• to skip "-e" package definitions;
• the newer versions of pip allow you to list outdated python modules;
• added -n1 to xargs, prevents stopping everything if updating one python module fails;

If you got this error about Python.h error:

...fatal error: Python.h...

Use this command to install the development library of Python:

[root@localhost mythcat]# dnf install python-devel.x86_64 python-devel.i686

Try to install also the devel libs for each error include.
Another example is this lib: opensslv.h
So install this:

[root@localhost mythcat]# dnf install openssl-devel.x86_64

Complete!

Try to run again the first command:

pip freeze --local | grep -v '^\-e' | cut -d = -f 1  | xargs -n1 pip install -U

See the first result of list outdated python modules:

[root@localhost mythcat]# pip list --outdated --format=freeze
CCColUtils==1.4
cryptography==1.5.3
evdev==0.6.1
fedmsg==0.18.2
ipykernel==4.5.2
M2Crypto==0.25.1
matplotlib==1.5.2rc2
mercurial==3.8.1
mysqlclient==1.3.7
psutil==4.3.0
pycryptopp==0.6.0.1206569328141510525648634803928199668821045408958
pyopencl==2015.2
pyOpenSSL==16.0.0
pyxattr==0.5.3
requests-kerberos==0.10.0
service-identity==14.0.0
Sphinx==1.5.3
SQLAlchemy==1.1.6
Tempita==0.5.1
tornado==4.4.2
Twisted==16.3.0
txZMQ==0.7.4

After this steps the result is this:

[root@localhost mythcat]# pip list --outdated --format=freeze
mysqlclient==1.3.7
pyopencl==2015.2
pyxattr==0.5.3

I will fix this next time.
