使用rbenv和Rails 4.2.6，当我运行bundle exec rails s或bundle exec rails c时，我会看到以下内容：
Ignoring sqlite3-1.3.11 because its extensions are not built. Try: gem pristine sqlite3 --version 1.3.11
就是这样，没有别的事情发生。如果我stop spring和run bundle exec rails c，则会显示以下内容：
Ignoring sqlite3-1.3.11 because its extensions are not built. Try: gem pristine sqlite3 --version 1.3.11
Ignoring sqlite3-1.3.11 because its extensions are not built. Try: gem pristine sqlite3 --version 1.3.11
Ignoring sqlite3-1.3.11 because its extensions are not built. Try: gem pristine sqlite3 --version 1.3.11

答案 0 :(得分：2)
问题是debug_inspector gem，您可以尝试删除Gemfile web-console中的bundle install gem，然后再次运行服务器。
更新：
或者如果您想保留web-console gem，您可以尝试删除已安装的所有gem，然后重新捆绑再次安装它们。根据{{3}}上的这个问题。
