Don't use easy_install. Use pip.

Pip has many advantages compared to easy_install:

• All packages are downloaded before installation. Partially-completed installation doesn’t occur as a result.

• Care is taken to present useful output on the console.

• The reasons for actions are kept track of. For instance, if a package is being installed, pip keeps track of why that package was required.

• Error messages should be useful.

• The code is relatively concise and cohesive, making it easier to use programmatically.

• Packages don’t have to be installed as egg archives, they can be installed flat (while keeping the egg metadata).

• Native support for other version control systems (Git, Mercurial and Bazaar)

• Uninstallation of packages.

• Simple to define fixed sets of requirements and reliably reproduce a set of packages.
