Rails找不到宝石。 ＆＃34;在任何来源中找不到..＆＃34;

Question

我最近使用rbenv设置了Ruby on Rails。但由于某种原因，我得到了：＆＃34;无法在任何来源中找到shoulda-matchers-3.1.1＆＃34;当我尝试做一个rails生成脚手架命令。这是我的宝石环境：

RubyGems Environment:

当我运行gem list时，它会显示：

sass-rails (5.0.4)
sdoc (0.4.1)
shoulda-matchers (3.1.1)
spring (1.7.1)
sprockets (3.6.0)

我已经尝试过gem install shoulda-matcher，捆绑安装，捆绑更新，gem安装捆绑，gem安装捆绑，gem更新 - 系统等等。它说我已经拥有它但它仍然一直给我这个错误。请帮忙。 d：

您可能需要每次为bundle exec添加bundle exec rails g前缀，例如bundle exec。

如果您因输入bundle install --binstubs 而生病，可以安装binstubs，如
