我正在Nitrous.io上做一个月Rails的教程.有一次，我的树上出现了一些奇怪的文件，我删除了它们.一切都停止了工作.

I was doing One Month Rails's tutorial on Nitrous.io. At one point, some weird files appeared on my tree, and I deleted them. Everything stopped working.

我跑了

$ git add . $ git checkout -f

并恢复了树.

但是，当我跑步时:

$ rails server

我得到:

action@first-project-48185:~/pinteresting$ rails server -bash: rails: command not found

我也尝试过:

$ ruby -v #and got an older version, so I reinstalled it $ rails -v action@first-project-48185:~/pinteresting$ rails -v -bash: rails: command not found

我跑步时:

$ ruby -v #on MAC terminal, I get the correct version $ rails -v #on MAC terminal, I get the correct version

有趣的是，当我跑步时:

Interestingly, when I run:

$ rails server or $ rails server -p 4000

我得到:

Franciscos-MacBook-Pro:pinteresting franciscomello$ rails server /Library/Ruby/Gems/2.0.0/gems/sqlite3-1.3.8/lib/sqlite3.rb:6:in `require': cannot load such file -- sqlite3/sqlite3_native (LoadError)

以及下面的其他文字:

令人沮丧的是我正处于最大状态，没有任何错误或错误:(

What's frustrating is I was on my largest streak without any errors or bugs :(

有什么想法吗?

推荐答案

我不能说出Rails为什么不再因这些错误而工作，但我建议您重新安装Rails.运行以下命令以重新安装Rails:

I can't tell why Rails is no longer working from those errors, but I would recommend reinstalling rails. Run the following command to reinstall Rails:

gem install rails

从这里您应该可以运行rails server.

From here you should be able to run rails server.

如果Gemfile包含需要安装的其他gem，也可以在项目目录中运行bundle install.

You could also run bundle install within the project directory if your Gemfile includes other gems which need to be installed.
