【问题描述】：

我刚刚升级了我的应用程序以使用 Ruby 2.4.0，在捆绑过程中没有任何错误。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)

我在本网站的其他答案中发现您需要将 gem 'therubyracer' 添加到您的 Gemfile 中，但自从我的应用程序创建以来我已经有了。

我的机器上也安装了最新版本的 NodeJS。

有没有其他人遇到过这个错误并且知道如何解决？

Gemfile 中的uglifier 配置：gem 'uglifier', '~> 3.0.4'

【问题讨论】：

运行命令包更新，然后重试。

@Bharatsoni 这是我尝试的第一件事。

出于好奇，您正在使用什么操作系统。我在尝试让这个 gem 在 windows10 上运行时遇到问题

@Brad 运行 Ubuntu 16.10

能否请您发布Gemfile.lock 的[所有相关部分]（特别是uglifier 的哪个版本？），以及完整的回溯（如果有的话）？

【参考方案1】：

这是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 Ruby 2.4.0 中的 unification of Fixnum and Bignum into Integer 引起的。 Here 是解决问题的拉取请求，它实际上在于therubyracer，而不是uglifier。

目前，作为临时修复，您可以将 Gemfile 配置为使用 repo 的 master 分支：

gem 'therubyracer', git: 'https://github.com/cowboyd/therubyracer.git'

更新：therubyracer 版本 0.12.3 现已更名为 released，其中包括上述对 ruby​​ 2.4 支持的修复。
