ruby-on-rails – 设计问题:TypeError – [17]不是符号

前端之家收集整理的这篇文章主要介绍了ruby-on-rails – 设计问题:TypeError – [17]不是符号前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我最近运行了一个捆绑更新,现在我变得很奇怪了

类型 – [17]不是符号错误.

这是完整的错误消息:

我完全不知道可能会突然造成什么.

不知道这是否有帮助,但这是我的Gemfile.lock:

这是我的Gemfile:

source 'https://rubygems.org'

gem 'rails','3.2.13'

group :assets do
  gem 'sass-rails','~> 3.2.3'

解决方法

这里有几点需要注意:

>在Gemfile中指定要更新的最大版本更安全
>您的会话未正确反序列化 – 这是您看到的异常的原因
>如果您在使用单个gem时遇到问题并需要更新,请使用bundle update< gem name>

指定最大Gem版本

您应该在Gemfile中使用pessimistic version constraint(〜>运算符).这基本上允许您说宝石只能更新到更高的补丁级别.

Ruby开发人员倾向于使用具有三个数字的版本号标准:x.x.x,例如2.0.1.第一个数字是主要版本,第二个数字是次要版本,第三个数字是补丁.

主要版本更新可能会破坏旧功能.如果从1.x.x升级到2.x.x,则可能是一个痛苦的过程.次要版本更新应添加功能,在极少数情况下,更改现有功能,但它应向后兼容.补丁级别更新应该是纯粹的错误修复.

悲观版本约束可用于表示“仅允许补丁级别更新”.例如:

gem 'devise','~> 2.2.3'  # Only the '.3' can increase,e.g. 2.2.4,2.2.5

如果您为所有宝石执行此操作,那么您可以合理地确定捆绑更新会将gems更新为兼容版本.在你的Gemfile中

gem 'devise','>= 2.2.3'

这可能会允许安装设备3.0.0,你几乎可以保证这将是有问题的.

最好找到有效的gem配置,然后使用悲观版本约束将Gemfile锁定为仅补丁级别更新.

会话反序列化

看起来设计已经更新,这导致会话反序列化问题.您可以查看旧版本的Gemfile.lock,然后降级到正在运行的设计版本.或者,如果您在会话中没有任何关键内容并使用新版本,则可以清除缓存.

更新单个宝石

运行捆绑包更新将尝试更新Gemfile中的所有gem.如果您只需要更新单个gem,请使用bundle update< gem name>.所有其他人将保持相同的版本.
