“无法在另一个目录中初始化新的Rails应用程序，请键入'rails'以获取帮助." [英] "Can't initialize a new Rails application within the directory of another, please Type 'rails' for help."

问题描述

我只是从Rails开始，我正在练习基本的ruby命令，其中之一是rails new myproject命令.

I'm just starting out with rails and I'm practicing the basic ruby commands, one of which is the rails new myproject command.

我的项目位于Aptana工作区目录下，我在其中使用了命令行，而Aptana都在此处创建了项目.经过几次创建以及rails s命令和删除后，当我尝试生成新的rails项目时，我已经开始收到以下错误消息:

My projects are under the Aptana workspace directory where I've used the command line and Aptana both to create projects there. After a few creations and rails s commands and deletions, I've started getting this error message when I try to generate a new rails project:

"无法在以下目录中初始化新的Rails应用程序 另外，请输入"rails"以获取帮助."

"Can't initialize a new Rails application within the directory of another, please Type 'rails' for help."

这不仅在我在Aptana工作空间目录下创建一个新项目(rails new myproject)时发生，而且在我直接在工作空间目录内使用命令rails new .时也会发生.有人可以向我解释冲洗滑轨需要做什么，以便知道我在那里不再有项目吗?我做了什么才能做到这一点?

This doesn't just happen when I create a new project (rails new myproject) under the Aptana workspace directory, but also when I use the command rails new . directly inside the workspace directory. Can someone explain to me what I need to do to flush rails so it knows I don't have a project there anymore? What did I do to make this happen?

推荐答案

我不记得要寻找什么滑轨.解决此问题的最快方法是完全清空受影响的目录.

I don't remember what rails looking for. The quickest way to solve this issue is to completely empty the affected directory.

最有可能存在一些隐藏的文件或目录，这些文件或目录会阻止Rails创建新项目.用ls -a来看，该目录中可能有一个.bundle文件夹.

Most likely there are some hidden files or directories which prevents rails from creating a new project. Look at that with ls -a probably there is a .bundle folder inside that dir.
