Ruby on rails 无法在my rails应用程序中安装fog gem

我在我的应用程序中使用了s3的fog gem。 捆绑程序无法继续使用fog gem。 每当我尝试使用fog gem捆绑安装时，捆绑程序都会出错。但是，当我评论出雾宝石，它是好的

bash:

bundle install

此gem安装安装在Ubuntu 16.x上，但不安装在我的Ubuntu 18.x上

提前谢谢

我遇到了同样的问题，然后我在gem文件中使用了类似的

gem'fog aws'

gem 'fog-aws'
gem 'fog'

然后，

bundle安装

解决了我的问题

---

我想这会对您有所帮助。

在这种情况下，您只需要使用S3，而不是

gem 'fog'

改用

gem 'fog-aws'

---

在你的gem文件中，它应该可以工作。

我重新启动了我的

Ubuntu

OS，然后解决了这个问题。
