安装后无法立即找到bcrypt

Question

在Rails4.1项目中，我只是添加了devise并运行bundle install。在那之后，由于缺少bcrypt，命令无法工作：

$ rails c
Could not find bcrypt-3.1.9 in any of the sources
Run `bundle install` to install missing gems.
$ rails generate devise:install
Could not find bcrypt-3.1.9 in any of the sources
Run `bundle install` to install missing gems.
$ bundle exec rails generate devise:install
Could not find bcrypt-3.1.9 in any of the sources
Run `bundle install` to install missing gems.

即使很明显它已经安装了：

$ bundle show

Answer 1

这是spring的一个问题(我知道，wtf?)。基本上，我是这样做的：

$ ps aux | grep spring

wendybeth      32281   0.0  0.2  2490496  16280   ??  S    Fri01PM   0:00.79 spring server | marketing | started 75 hours ago    

$ kill 32281

作为一个整体，我是Rails和开发的新手，我很紧张地说，这个解决方案没有任何副作用。我在这里找到的：

https://jasonplayne.com/web-dev/rails-generate-could-not-find-in-any-of-the-sources

这对我很管用。我不知道为什么-所以除非你自己理解，否则请谨慎使用。:/

Answer 2

尝试使用bundle exec rails c，在Gemfile中的gem上下文中运行rails服务器。

Answer 3

尝试以下操作：

gem update bundler
bundle install 
rails console
