Answer 1

实际上你的rake版本是0.9.2

虽然您的应用需要0.8.7

所以首先通过此命令卸载rake 0.9.2

gem uninstall rake -v=0.9.2

然后通过此命令安装rake 0.8.7

gem install rake -v=0.8.7

希望你的问题能解决........

Answer 2

运行这些命令，问题将解决第1步：安装rake gem install rake -v＆＃39; 0.8.7＆＃39;

第2步：安装bundler gem install bundler

第3步：捆绑安装

它将解决问题..

Answer 3

即使我在使用RubyMine运行应用程序时遇到了同样的问题。

我采取的措施： 1）我在我的机器上安装了新的Ruby。 2）在环境变量中改变了Ruby的路径。 3）使用以下步骤更改了RubyMine中Ruby的路径： - a）点击文件 - ＆gt; 设置 - ＆gt; Ruby SDK和Gems 4）然后运行 bundle install

在任何来源中都找不到rake-0.8.7（Bundler :: GemNotFound）
