Install Python 3 on CentOS 6.4 minimal
Environment: CentOS6.4 minimal
Require Package (C Complier)
Require Package (C Complier)
#yum groupinstall "Development Tools"
Go to desired path for store the downloaded file. e.g.
#cd /tmp
Download Python 3.3.1
#make
or
#make altinstall
PS:
For the version 3.4, pip is included in Python package.
You may get the following error, which means you have not install "Development Tools" well
Ignoring ensurepip failure: pip 6.0.8 requires SSL/TLS
Check if installed
#python3.3 --version
Optional:
There are python2.6 & 3.3.1 in my CentOS concurrently.
When I call "python", the version is 2.6.
I would like change it instead of typing in "python3.3" every time, so just link it up as below
PS: The path may be different.
#ln -sf /usr/local/bin/python3.3 /usr/bin/python
Don't do the strike through procedure above, it will make "yum install" crash.
