How can I fix it? This error came after I changed the bundle version

CodePudding user response：

It is as the error message says. The versions you specify in the gem file is not available. This happens because each bundle version only supports down to a certain version, for example it can download any version from 2 and up but version 1 is not available. I see your gems are outdated, and you should consider to just update them. Unless you have done something version specific you should not need these restrictions anymore for rails version 4.2. If not you have to roll back your bundle version.

CodePudding user response：

The error is mimemagic, required by paperclip.

You'll have to upgrade or provide the mimemagic gem from source.
This happened to me and had to obtain the code from an old project in order to supply it.
