无法运行服务器或捆绑更新

Question

Ruby和Rails在我的Mac上运行良好,但我突然遇到了一些问题.当我尝试运行服务器或生成模型(即无论如何使用'rails'命令)时,我收到此错误

/Users/tm/.rbenv/versions/1.9.3-p327/lib/ruby/gems/1.9.1/gems/bundler-1.2.3/lib/bundler/rubygems_integration.rb:187:in `stub_source_index170': uninitialized constant Gem::SourceIndex (NameError)

我随机尝试运行bundle update并得到此错误

Fetching gem metadata from https://rubygems.org/..

NoMethodError: private method `open' called for Gem::Package:Class
An error occurred while installing rake (10.0.4), and Bundler cannot continue.
Make sure that `gem install rake -v '10.0.4'` succeeds before bundling.

按照说明,我安装了rake

gem install rake -v '10.0.4'
Successfully installed rake-10.0.4
Installing ri documentation for rake-10.0.4

但是,如上所述,我使用'rails'命令和bundle更新得到了相同的错误.

多个项目文件夹中发生错误.

今天和昨天之间的唯一区别(当一切正常时)是我昨晚安装了jekyll,并且在进行故障排除时,运行了一些"sudo"命令,我通常不需要运行它们.我不知道这是否与当前的问题有关.我只是提供上下文.

我不知道接下来要做什么.你能说一下我的尝试吗？

Answer 1

很可能ruby/gem/bundler的版本控制可能已经切换或更改.你可以做的事情是

1. 检查你所使用的红宝石版本ruby -v.
2. 然后rvm use 1.9.3再次进入您的终端.
3. 我记得读Gem :: Package不再支持open方法.所以尝试更新你的gem系统(gem update --system).
4. 然后,您可以再次捆绑您的gem文件(最好再次更新您的捆绑包,这可能是问题,所以gem install bundler)
5. 确保在捆绑之前删除.lock文件.
