無法在本地運行 Rails 服務器

[英]Cannot run Rails server locally

問題描述

我一直在搞亂我的 Rails 項目，現在我不能再在本地運行我的 Rails 服務器了。

我嘗試使用rails server像 norma 一樣運行它，但它沒有啟動。

請看下面的堆棧，也許有人可以指出我哪里出錯了？

Your Gemfile lists the gem pg (>= 0) more than once.
You should probably keep only one of them.
Remove any duplicate entries and specify the gem only once.
While it's not a problem now, it could cause errors if you change the version of one of them later.

有任何想法嗎？ 我什至不確定在這里谷歌搜索什么。

謝謝！

在錯誤 output 中尋找可能的線索：

1 - 它正在加載您的應用程序配置：

20: from .../conference/conference/config/application.rb:11:in `<module:Conference>'

2 - 從那里加載figaro ：

12: from .../gems/figaro-1.2.0/lib/figaro/rails/railtie.rb:5:in `block in <class:Railtie>'

3 - Figaro 正在解析一些東西：

 4: from .../figaro-1.2.0/lib/figaro/application.rb:60:in `parse'

4 - 這是一個 YAML 文件（正在使用 Psych）：

 ...psych.rb:456:in `parse':

5 - 此 YAML 文件的第 14 行存在錯誤：

could not find expected ':' while scanning a simple key at line 14 column 1 (Psych::SyntaxError)

現在我們可以嘗試猜測一下：

Figaro 通常從config/application.yml加載設置。 你有沒有檢查那里的錯字？

您的 Gemfile 不止一次列出 gem pg (>= 0)。

Gems 有時被放在組中（例如test 、 development和production ）。 這樣您就可以在特定組上運行bundle install （ Bundler 文檔參考）。

組通常以以下格式編寫：

group :development do
  gem 'example1', '~> 1.23'
  gem 'example2', '> 1.00'
  gem 'example3', '>= 2.34'
end

您可以將未放置在組下的寶石視為在全局組中。 這意味着它們可以在Gemfile中定義的所有組中訪問。

這里可能發生的情況是pg gem 不止一次地放在同一個組下。

所以可能解決這個問題：

  1. Go 到Gemfile
  2. 刪除共享同一組的額外pg gem（每組只保留一個）
  3. 運行bundle install
  4. 運行rails server
