Rails 春季更新后无法运行迁移 [英] Couldn't run migration after spring update in Rails

问题描述

我在运行任何迁移时遇到错误:

I am facing a error when I run any migration as:

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'

因此，通过一些谷歌搜索，我运行了 bundle update spring，它解决了上述错误，并且我能够删除/添加迁移.同样，如果我运行 rake db:migrate，我会收到如下错误:

So with some googling I run bundle update spring, which solved the above error, and I am able to remove/add migrations. Again if I run rake db:migrate, I am getting error as:

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'

    ** 33 stack trace lines skipped **

/var/lib/gems/1.9.1/gems/activerecord-4.1.4/lib/active_record/railties/databases.rake:34:in `block (2 levels) in <top (required)>'
Tasks: TOP => db:migrate

请帮帮我.

推荐答案

在运行 bundle update 和更新 Spring 后，我在运行控制台时收到以下错误:

After running bundle update and updating Spring, I was getting the following error when running the console:

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

我遵循了这个 Github 问题中的建议并运行:

I followed the recommendations in this Github issue and ran:

spring stop

这为我解决了这个问题.

This fixed the issue for me.
