当我运行任何迁移时,我遇到错误：
raj@notebook-pc:~/Desktop/Projects/invoicemanagement$rails g migration RemoveDescriptionOfGoodsFromInvoiceDetails description_of_goods:string
Warning: You're using Rubygems 1.8.23 with Spring. Upgrade to at least Rubygems 2.1.0 and run `gem pristine --all` for better startup performance.
/var/lib/gems/1.9.1/gems/bundler-1.9.0/lib/bundler/runtime.rb:34:in `block in setup': You have already activated spring 1.3.3,but your Gemfile requires spring 1.3.2. Prepending `bundle exec` to your command may solve this. (Gem::LoadError)
from /var/lib/gems/1.9.1/gems/bundler-1.9.0/lib/bundler/runtime.rb:19:in `setup'
** 11 stack trace lines skipped **
from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:35:in `require'
所以有一些谷歌搜索我运行捆绑更新弹簧,解决了上述错误,我可以删除/添加迁移.再次,如果我运行rake db：migrate,我得到错误：
rake aborted!
StandardError: An error has occurred,this and all later migrations canceled:
undefined method `to_sym' for nil:NilClass/var/lib/gems/1.9.1/gems/activerecord-4.1.4/lib/active_record/connection_adapters/abstract/schema_definitions.rb:216:in `column'

请帮帮我.
解决方法
运行bundle更新和更新Spring之后,运行控制台时出现以下错误：
There is a version mismatch between the spring client and the server. You should restart the server and make sure to use the same version. CLIENT: 1.3.4,SERVER: 1.3.3
我按照this Github issue的建议,跑了：
spring stop
这解决了我的问题.
