Bundler无法继续;错误分析“的Gemfile”：（<unknown>）

Question

虽然使用这些安装说明，https://www.redmine.org/projects/redmine/wiki/HowTo_Install_Redmine_30x_on_Ubuntu_1404_with_Apache2_Phusion_Passenger_MySQL_Subversion_and_Git_%28Gitolite%29，

当我执行以下命令

bundle install --without development test postgresql sqlite 

，并得到了下面的错误我遇到了一个问题。

redmine@zaps-VirtualBox:~/redmine$ bundle install --without development test postgresql sqlite 

[!] There was an error parsing `Gemfile`: (<unknown>): found character that cannot start any token while scanning for the next token at line 10 column 13. Bundler cannot continue. 

# from /opt/redmine/redmine-3.0.4/Gemfile:57 
# ------------------------------------------- 
# database_config = YAML::load(ERB.new(IO.read(database_file)).result) 
# adapters = database_config.values.map {|c| c['adapter']}.compact.uniq 
# ------------------------------------------- 

我检查这个工具，http://www.yamllint.com/ YAML语法，但没有摇出。

正如代码中所见，我评论了有问题的行并简单地重写了它（一位IT研究员建议制表符语法或空白作为问题）也无济于事。

我的Gemfile如下;

if Gem::Version.new(Bundler::VERSION) < Gem::Version.new('1.5.0') 
    abort "Redmine requires Bundler 1.5.0 or higher (you're using #{Bundler::VERSION}).\nPlease update with 'gem update bundler'."

什么会解决冲突？是否需要更多信息？我在哪里可以找到有关'令牌'的信息？

Redmine从Gemfile加载config/database.yml文件以确定访问配置的数据库所需的正确gem。现在，您的database.yml似乎无效，无法加载。因此，bundler无法完成安装所需的宝石。

要解决此问题，请确保config/database.yml在语法上是正确的YAML。检查您的database.yml文件中第10行第13列的错误。
