我刚刚第一次从 GitHub 克隆了一个存储库。

我去我的本地机器上检查了它，所以在我的 mac 上的本地存储库中我运行了以下命令

bin/rails 服务器

我收到以下错误:

无法在任何来源中找到 activesupport-5.0.0.1 运行 bundle install 以安装缺少的 gem。

然后我按照建议运行了 bundle install 命令，但是它给了我以下错误

安装 oj (2.12.14) 时出错，Bundler 无法继续。 确保 gem install oj -v '2.12.14' 在捆绑之前成功。

所以我按照建议运行了:gem install oj -v '2.12.14'

然后我收到一条非常长的消息，其中包含警告和错误(见下文)。有什么想法吗？

Gem files will remain installed in /usr/local/lib/ruby/gems/2.4.0/gems/oj-2.12.14 for inspection.

Results logged to /usr/local/lib/ruby/gems/2.4.0/extensions/x86_64-darwin-16/2.4.0/oj-2.12.14/gem_make.out

最佳答案

Fixnum 不再是 ruby​​ 2.4 中的东西。要么将你的 ruby​​ 降级，要么将 oj 更新到支持 ruby​​ 2.4 的 2.16.1。

关于ruby-on-rails - 错误 : Error installing oj:，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42316668/
