Answer 1

看來您的 postgres gem 版本與該版本的 activesupport 不兼容。

請發布這些文件以便我們獲得更多信息： - .ruby-version（如果存在） - .ruby-gemset（如果存在） - .rvmrc（如果存在） - Gemfile - Gemfile.lock

我猜您的 ActionSupport（一個 rails 庫）已升級，並且您系統的 PostgreSQL 無法升級到您的應用程序所依賴的 postgres Gem 版本。

Answer 2

根據問題中提到的描述和日志，似乎有一個損壞的PATH ，但是在瀏覽了一些鏈接后，發現下面提到的鏈接表明 ruby​​-2.3.1 中存在錯誤。

https://bugs.ruby-lang.org/issues/9760#note-14

作為一種快速解決方法，我建議安裝 ruby​​-2.3.3。 執行下面提到的命令來安裝相同的：

rvm install ruby-2.3.3
rvm gemset empty
gem install bundler
bundle install

它肯定會工作，因為我也在我的本地機器上安裝了這個 ruby​​ 版本並且它工作正常。
