安装 RadRails 时出现依赖错误
我正在尝试安装适用于 Eclipse 的 Aptana RadRails/Aptana Studio 插件，但遇到了奇怪的依赖错误。详细信息如下：
操作系统：Ubuntu 11.04 Eclipse 版本：3.5（伽利略） RadRails 版本：Aptana Studios Plugin 版本 3.0.4
注意：我还安装了 PyDev 插件
无论如何，我去 Eclipse 中安装新软件并输入 URL（http://download.aptana.com/studio3/plugin/install ） 然后选中“Aptana Studio 3 插件”框并单击“下一步”，我收到此错误：
由于依赖项冲突，无法完成安装。 正在安装的软件：Aptana Studio 3 Plugin 3.0.4.201108101432-7E37B7HFEHCdSHSV5R_IyJetqA_B (com.aptana.feature.studio.feature.group 3.0.4.201108101432-7E37B7HFEHCdSHSV5R_IyJetqA_B) 当前安装的软件：PyDev for Eclipse 2.2.1.2011071313 (org.python.pydev.feature.feature.group 2.2.1.2011071313) 一次只能安装以下其中一项： Pydev - Python 开发环境 1.5.7.2010050621 (org.python.pydev 1.5.7.2010050621) Pydev - Python 开发环境 1.5.5.2010030420 (org.python.pydev 1.5.5.2010030420) Pydev - Python 开发环境 1.6.2.2010090812 (org.python.pydev 1.6.2.2010090812) Pydev - Python 开发环境 1.6.1.2010080312 (org.python.pydev 1.6.1.2010080312) Pydev - Python 开发环境 2.2.1.2011071313 (org.python.pydev 2.2.1.2011071313) Pydev - Python 开发环境 1.6.5.2011020317 (org.python.pydev 1.6.5.2011020317) Pydev - Python 开发环境 1.5.8.2010062823 (org.python.pydev 1.5.8.2010062823) Pydev - Python 开发环境 1.5.6.2010033101 (org.python.pydev 1.5.6.2010033101) Pydev - Python 开发环境 1.5.9.2010063001 (org.python.pydev 1.5.9.2010063001) Pydev - Python 开发环境 2.2.2.2011082312 (org.python.pydev 2.2.2.2011082312) Pydev - Python 开发环境 1.5.4.2010011921 (org.python.pydev 1.5.4.2010011921) Pydev - Python 开发环境 1.5.3.1260479439 (org.python.pydev 1.5.3.1260479439) Pydev - Python 开发环境 2.2.1.2011073123 (org.python.pydev 2.2.1.2011073123) Pydev - Python 开发环境 2.2.0.2011062419 (org.python.pydev 2.2.0.2011062419) Pydev - Python 开发环境 1.5.1.1258496115 (org.python.pydev 1.5.1.1258496115) Pydev - Python 开发环境 1.6.4.2011010200 (org.python.pydev 1.6.4.2011010200) Pydev - Python 开发环境 1.6.3.2010100513 (org.python.pydev 1.6.3.2010100513) Pydev - Python 开发环境 2.0.0.2011040403 (org.python.pydev 2.0.0.2011040403) Pydev - Python 开发环境 2.1.0.2011052613 (org.python.pydev 2.1.0.2011052613) Pydev - Python 开发环境 1.6.0.2010071813 (org.python.pydev 1.6.0.2010071813) Pydev - Python 开发环境 1.6.2.2010090711 (org.python.pydev 1.6.2.2010090711) Pydev - Python 开发环境 1.5.9.2010063000 (org.python.pydev 1.5.9.2010063000) Pydev - Python 开发环境 1.5.0.1251989166 (org.python.pydev 1.5.0.1251989166) Pydev - Python 开发环境 1.5.2.1260362205 (org.python.pydev 1.5.2.1260362205) 无法满足依赖关系： 来自：Aptana Studio 3 插件 3.0.4.201108101432-7E37B7HFEHCdSHSV5R_IyJetqA_B (com.aptana.feature.studio.feature.group 3.0.4.201108101432-7E37B7HFEHCdSHSV5R_IyJetqA_B) 至：org.python.pydev.feature.feature.group [2.2.1.2011073123] 无法满足依赖关系： 来自：扩展调试插件2.2.1.2011073123（com.python.pydev.debug 2.2.1.2011073123） 至：捆绑org.python.pydev 2.2.1.2011073123 无法满足依赖关系： 来自：PyDev for Eclipse 2.2.1.2011071313 (org.python.pydev.feature.feature.group 2.2.1.2011071313) 至：org.python.pydev [2.2.1.2011071313] 无法满足依赖关系： 来自：PyDev for Eclipse 2.2.1.2011073123（org.python.pydev.feature.feature.group 2.2.1.2011073123） 至：com.python.pydev.debug [2.2.1.2011073123]
我该怎么办？
I'm trying to install the Aptana RadRails/Aptana Studio plugin for Eclipse and I'm getting a strange dependency error. Here are the details:
OS: Ubuntu 11.04
Eclipse version: 3.5 (Galileo)
RadRails version: Aptana Studios Plugin version 3.0.4
Note: I also have the PyDev plugin installed
Anyway, I went to install new software in Eclipse and typed in the URL (http://download.aptana.com/studio3/plugin/install)
then checked the box for "Aptana Studio 3 plugin" and clicked next, and I got this error:
Cannot complete the install because of a conflicting dependency.

Studio 3 默认包含 PyDev，因此您需要先从当前 Eclipse 安装中卸载现有的 PyDev，然后再安装 Studio 3 插件。
希望这有帮助。
Studio 3 includes PyDev by default, so you would need to uninstall the existing PyDev from the current Eclipse installation first and then install Studio 3 plugins.
Hope this helps.
