我正在尝试运行一个bundle install上的rails项目从git拉。当我运行bundle install时，我得到以下错误:
/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)

这是我的Gemfile:

经过一番挖掘，我认为这可能是rvm的问题，因为我试图从git中拉出一个旧项目，但仍然无法运行bundle install。我还尝试在本地复制一个项目，运行安装并启动一个新项目，但都没有成功。
重新安装rvm后，我运行rvm use ruby --install --default，得到以下错误(类似于上面)
/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)

基本上我不能在计算机上开始一个新的rails项目。任何见解将不胜感激。
如果.yml文件中有语法错误，通常会出现此错误。看一看是否有错误。
您也可以尝试从主目录中删除. gemc文件。有可能错误就在这里
如果您仍在寻找答案(修补数据库后)。请尝试检查应用程序初始化时加载的其他yml文件，如secrets.yml, sidekiq.yml, webpacker.yml等。
在我的例子中，它抛出了如下错误:
/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)
但database.yml是完整的。问题出在secrets.yml。在几个地方使用了tab缩进
我最近有这个问题有这个问题。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
没有工作。我试过的:
- 重写application.yml
- 删除GEMFILE。锁定并重新安装所有宝石
- 更改键的值和名称
- 检查所有配置中的拼写错误
这些都不能解决问题。作为一个优秀的工程师，我把它烧了。我将我的项目克隆到一个新目录中，并重写了应用程序。Yml，这是有效的。两个版本都在同一个分支和同一个变更集上。
对于其他得到此错误的人，我得到了这个错误，结果是有不可见的unicode字符正在创建冲突。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
