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查看此应用程序。 请迅速回答。 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（包含您列出的文件夹的项目），然后运行：

rails server或简称rails s，在你确定你已经捆绑之后。

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，您必须更改它相应的网址）。

编辑：

根据您的更新，您需要一个 javascript 运行时。您可以为此使用therubyracer，因为大多数时候它默认包含在您的Gemfile 中，用于rails 项目。您应该检查您的Gemfile 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 s。
