所以我遇到了一个问题，我不知道如何在网络浏览器中访问它请告诉我如何在网络浏览器中看到这个应用程序。请快速回答。提前致谢

Your bundle is complete!
Use `bundle show [gemname]` to see where a bundled gem is installed.

Answer 1

根据文档，进入您的项目(具有您列出的文件夹的项目)，然后运行:

rails server 或简称 rails ，在您确保已捆绑之后。

您可以查看文档 here 。然后，您可以在浏览器中的 localhost:3000 中看到它，就像任何其他 ruby​​ Web 应用程序一样(只要您不在 rails server 命令上使用 -b 或 -p。如果这样做，则必须相应地更改此 url)。

编辑:

根据您的更新，您需要一个 javascript 运行时。您可以使用 therubyracer 来实现此目的，因为大多数情况下它默认包含在 Rails 项目的 Gemfile 中。您应该检查 Gemfile 中是否有 gem "therubyracer"，如果它被注释掉，请取消注释并重新捆绑，然后再次尝试 rails 。
