找不到宝石轨道(> = 0.a)(Gem :: GemNotFoundException) [英] can't find gem railties (>= 0.a) (Gem::GemNotFoundException)

问题描述

为此，我还看到了其他一些问题，尝试了他们的建议，但没有一个对我有用.

I've seen a few other issues for this, tried their recommendations, none of them worked for me.

我已经使用Rails大约一年了，刚开始一个新的Rails项目，突然遇到了问题.我卸载并尝试重新安装所有Ruby和Rails. Ruby很好，但Rails不好.

I've been using Rails for about a year, just started a new Rails project, and suddenly having issues. I uninstalled and tried reinstalling all of Ruby and Rails. Ruby is fine, but not Rails.

当我输入rails s时，我得到了can't find gem railties.即使我一直试图通过rbenv设置ruby 2.3.0，我当前的Ruby版本是ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin15].

When I enter rails s, I get the can't find gem railties. My current Ruby version is ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin15], even though I've been trying to set ruby 2.3.0 through rbenv.

如果我尝试rails -v来查看我正在运行的版本，则会收到相同的错误.我正在使用Mac OS X El Capitan版本10.11.6.

If I try rails -v to see what version I'm running, I get the same error. I'm using Mac OS X El Capitan version 10.11.6.

推荐答案

rvm osx-ssl-certs
rvm cleanup all
rvm reset

它对我有用！也许有些命令没用，我只是回顾了我的shell的历史:)

It works for me! Maybe some commands useless, I just retell the history of my shell :)
