升级到Ruby 2.4后，尝试加载'uglifier'宝石时出现错误（Bundler :: GemRequireError）

我刚刚将我的应用程序升级到使用Ruby 2.4.0版，绑定过程中没有出现任何错误。但是当我尝试启动服务器时，出现以下错误：
There was an error while trying to load the gem 'uglifier'. (Bundler::GemRequireError)
Gem Load Error is: wrong argument type Class (expected Module)

我在这个网站上的其他回答中发现，您需要在您的Gemfile中添加gem' therubyracer'，但是自从我创建我的应用程序以来，我已经有了这个Gem。

我的机器上也安装了最新版本的NodeJS。

有其他人遇到过这个错误并知道如何解决吗？

Gemfile中uglifier的配置：gem 'uglifier', '~> 3.0.4'

运行命令“bundle update”，然后再试一次。 - Bharat soni
@Bharatsoni 这是我尝试的第一件事。 - Severin
@Brad 正在运行 Ubuntu 16.10。 - Severin
请问您能否发布Gemfile.lock的[所有相关部分]（特别是uglifier的版本）以及完整的回溯信息（如果有的话）？ - Tom Lord
实际上不用了，见下面我的答案... - Tom Lord

这是在 uglifier 存储库上的一个未解决问题：Uglifier doesn't load with Ruby 2.4.0 using The Ruby Racer JS runtime。
这是由于在 Ruby 2.4.0 中将 Fixnum 和 Bignum 统一为 Integer 导致的。这里 是解决此问题的拉取请求，实际上问题出现在 therubyracer 而不是 uglifier。
目前，暂时的解决方法是，您可以配置您的 Gemfile 使用存储库的主分支：
gem 'therubyracer', git: 'https://github.com/cowboyd/therubyracer.git'
更新: therubyracer 版本 0.12.3 已经 发布, 包含了对于 Ruby 2.4 的支持修复。
