Ruby on Rails TypeError [英] Ruby on Rails TypeError

问题描述

我一直在研究ruby on rails应用程序，并且在做任何事情(包括安装gem，更新包，安装包)时遇到以下错误.

I have been working on a ruby on rails application and ran into the following error when doing just about anything, including installing a gem, updating the bundle, installing the bundle.

ERROR: While executing gem ... (TypeError) incompatible marshal file format (can't be read) format version 4.8 required; 31.139 given

ERROR: While executing gem ... (TypeError) incompatible marshal file format (can't be read) format version 4.8 required; 31.139 given

我已经卸载了RVM并从中完全删除了所有文件，然后尝试安装gem，但是仍然出现相同的错误.

I have uninstalled RVM and completely removed all files from it, then tried to install a gem, but still get the same error.

推荐答案

我遇到了这个确切的问题，花了我一辈子才弄清楚.要修复它，我运行了以下命令:

I had this exact problem, and it took me forever to figure it out. To fix it, I ran the following command:

bundle install --full-index

我的猜测是，在计算机锁定后，我的rubygems索引最终损坏了，该命令强制重新下载该索引.

My guess is that I ended up with a corrupted rubygems index after my computer locked up, and this command forces a fresh download of the index.

希望这对遇到此问题的人有所帮助.

Hopefully this helps someone who runs into this.
