您已经激活了机架1.6.0，但是您的Gemfile需要机架1.6.4. [英] You have already activated rack 1.6.0, but your Gemfile requires rack 1.6.4

问题描述

类似于 bundle update rake或rm Gemfile.lock && bundle install似乎也无济于事，到目前为止，我唯一的解决方案是在Gemfile.lock中手动将rack (1.6.4)更改为rack (1.6.0).

bundle update rake nor rm Gemfile.lock && bundle install seem to help, the only solution I have so far is manually changing rack (1.6.4) to rack (1.6.0) in Gemfile.lock.

推荐答案

您需要卸载一个不需要的机架版本.

you need to uninstall one version of rack which is not required.

请这样做

gem uninstall rack -v 1.6.0
