Aptana Studio 3 - 在服务器上运行（不适用于某些项目）

Question

我能够“在服务器上运行/调试”一个新的Rails项目，在Aptana中创建。

但是，对于现有项目，“Run/Debug on Server”无提示失败。

我还没有弄清楚为什么行为不同。

以下是日志中显示的内容。

Answer 1

我有同样的问题。我不知道发生了什么，但这是我做了什么来解决这个问题：

1. 转到Preferences->Aptana Studio->Web Servers。
2. 点击New。
3. 从列表中选择Rails server。

在对话框中： - 这是出现同名服务器（我不知道，但它可能是更好地把你设置服务器的项目的确切名称中输入名称下面的列表）;从想要配置服务器的列表中选择一个项目名称;离开0.0.0.0和未触及。

点击确定&享受！
