Question

我正在尝试在从git中提取的rails项目上运行bundle install。当我运行bundle install时，我收到以下错误：

    /Users/jordandeutsch/.rvm/rubies/ruby-2.2.1/lib/ruby/2.2.0/psych.rb:370:in     `parse': (<unknown>): could not find expected ':' while scanning a simple key at     line 3 column 1 (Psych::SyntaxError)

    from /Users/jordandeutsch/.rvm/rubies/ruby-2.2.1/bin/gem:21:in `<main>'

这是我的Gemfile：

source 'https://rubygems.org'

end

end

经过一番挖掘后，我认为这可能是rvm的一个问题，因为我试图从git中删除一个旧项目，但仍然无法运行bundle install。我还尝试在本地复制项目并运行安装并启动一个新项目都没有成功。

重新安装rvm后我运行rvm use ruby --install --default并收到以下错误（类似于上面的内容）

/Users/jordandeutsch/.rvm/rubies/ruby-2.2.3/lib/ruby/2.2.0/psych.rb:370:in `parse': (<unknown>): could not find expected ':' while scanning a simple key at line 3 column 1 (Psych::SyntaxError)

基本上我无法在计算机上开始新的rails项目。任何见解将不胜感激。

Answer 1

如果.yml文件中存在语法错误，通常会出现此错误。看看你是否能找到任何错误。

您也可以尝试从主目录中删除.gemrc文件。可能是错误在那里。

Answer 2

我最近遇到过这个问题。我的问题：

.application.yml

default: &default
 FOO_KEY: 'XXXXX'

development:
  <<: *default

test:
  <<: *default

工作得很好。

default: &default
  FOO_KEY: 'asdf'
  BAR_KEY: 'XXXXXXXXXXX'
  FOO_BAR: 'XXXXXXXXXXXX'

development:
  <<: *default

test:
  <<: *default

没用。我尝试了什么：

重写application.yml
删除GEMFILE.lock并重新安装所有宝石
更改键的值和名称
检查拼写错误的所有配置

这些都没有帮助解决问题。因此，作为一名优秀的工程师，我把它烧成了地面。我将我的项目克隆到一个新目录并重新编写application.yml，这很有用。两个repos都在同一个分支上，并且在同一个变更集上。

Answer 3

如果您仍在寻找答案（多次修补了database.yml之后），请尝试检查在应用程序初始化时加载的其他yml文件，例如secrets.yml，{ {1}}，sidekiq.yml左右。

在我的情况下，它引发了如下错误：

webpacker.yml

但是/home/abhishek/.rvm/gems/ruby-2.3.7/gems/railties-4.2.10/lib/rails/application/configuration.rb:115:in `rescue in database_configuration': YAML syntax error occurred while parsing /home/abhishek/Workspace/clearfunds/clearfunds-web/config/database.yml. Please note that YAML must be consistently indented using spaces. Tabs are not allowed. Error: (<unknown>): could not find expected ':' while scanning a simple key at line 19 column 7 (RuntimeError)是完整的。问题出在database.yml中。在几个地方都使用过secrets.yml缩进。

Answer 4

对于其他遇到此错误的人，我遇到了此错误，结果发现存在不可见的unicode字符正在引起冲突。我找到了一个网站，显示这些字符在哪里：https://www.soscisurvey.de/tools/view-chars.php

（<unknown>）：找不到预期的＆＃39;：＆＃39;在第3行第1列扫描一个简单的键时（Psych :: SyntaxError）
