Answer 1

It looks like your Hex installation is damaged. Try the installation using mix local.hex --force .

You can also try manually downloading and installing the latest version.

 $ wget http://s3.amazonaws.com/s3.hex.pm/installs/1.1.0/hex-0.11.5.ez $ mix archive.install hex-0.11.5.ez 

Answer 2

• Run mix hex.info to verify that your version of Hex is out of date. (For example, Hex v0.7.5 .)
• Delete the ~/.mix , then run mix local.hex --force .
• Run mix hex.info again; version must be updated.
