ruby-on-rails - 运行捆绑安装时出现错误

Question

我想在我的应用程序中使用 stripe gem，我已将 stripe 添加到 gem 文件中，但之后当我进行捆绑安装时，出现错误“安装 unf_ext (0.0.7.2) 和 Bundler 时发生错误”无法继续。请确保在捆绑之前 gem install unf_ext -v '0.0.7.2' 成功。”我尝试捆绑安装 unf_ext 但仍然不起作用。我该如何解决这个问题？ 来源'https://rubygems.org '

由于您所使用的系统所需的依赖项存在各种问题，因此可能会发生此错误，因此请访问以下官方 gem 作者页面，确保您满足所有这些问题:

查看下面给出的开发人员主页，检查您是否满足所需的所有依赖项:

unf_ext 0.0.7.2 : Unicode Normalization Form support library for CRuby

=> 如果错误是由于缺少 gmkdir 导致的，则运行以下命令:

brew install coreutils

=> 如果错误是由于缺少相关的 C++ header 造成的，则运行以下命令:

yum install gcc-c++
