推荐答案

基于 https://github.com/bcardarella/client_side_validations/issues/494 看起来 CSV 将不再支持 Rails 4.

Based on https://github.com/bcardarella/client_side_validations/issues/494 it looks like CSV will not support Rails 4 for a little bit longer.

然而它也说明

在 Rails 4.0 发布后至少 2 个月内(​​希望不会那么长)，我认为 CSV 4.0 不会出现，因为 JavaScript 方面会发生重大变化.因为这需要更长的时间，人们会想要一个符合 Rails 4.0 的 CSV 版本，建议他们使用 master 分支，或者发布一个 alpha 或 pre 版本来部分满足他们，而我们更新可能是正确的选择.

I don't see CSV 4.0 coming out for at least 2 months after Rails 4.0 lands (hopefully not that long) as there will be major changes on the JavaScript side of things. Because it will take so longer and people will want a Rails 4.0 compliant version of CSV suggesting they use master branch or perhaps releasing a alpha or pre version to partially satisfy them while we update might be the correct option.

那么也许可以尝试从 git 中直接提取 csv ?有一个 4.0 beta 分支可能值得一试...

So perhaps try pulling csv right from git? There is a 4.0 beta branch that might be worth trying...

更新

CSV gem 不再积极维护.存储库中有 3 个不同的 4.0 分支，最近更新的是 4-0-useable (https://github.com/bcardarella/client_side_validations/branches/all).

The CSV gem is no longer actively maintained. There are 3 different 4.0 branches on the repository, and the most recently updated of which is 4-0-useable (https://github.com/bcardarella/client_side_validations/branches/all).

更新 2

正如@TheChamp 所说，CSV gem 现在支持 rails 4.2！

As @TheChamp says, the CSV gem now supports rails 4.2!
