I wrote a python3.4 script to fetch some data from an RSS feed that works just as expected. I wanted to create a cronjob to execute the script with my VPS (CentOS 5.11). The server have the regular python and python3.4 installed without problem (i can run python3.4 scripts without problem). The problem is that i need Beautiful Soup installed for python3.4 for my script to work, but when i try to install it, i receive an error from the server: I use pip3.4 install beautifulsoup
to install the module.
Exception:

I read about the virtual python environments, but i don't know if that will work the way that i wanted to work. I have root access to the server, i'm doing this through SSH.
Any help will be appreciated.
If i use pip3.4 --trusted-host pypi.python.org install <package_name>
i can upgrade pip3.4 and install urllib3, but when i try to install Beautiful Soup i receive this error:
