安装RadRails时出现依赖项错误

Question

我正在尝试为Eclipse安装Aptana RadRails/Aptana Studio插件，但我得到了一个奇怪的依赖错误。以下是详细信息：

操作系统:Ubuntu11.04 Eclipse版本: 3.5 (Galileo) RadRails版本: Aptana Studios插件版本3.0.4

注意:我还安装了PyDev插件

不管怎样，我在Eclipse中安装了新软件，输入了网址(http://download.aptana.com/studio3/plugin/install)，然后选中了"Aptana Studio3插件“的复选框，然后点击next，我得到了这个错误：

无法完成安装，因为存在冲突的依赖项。正在安装的软件: Aptana Studio3 Plugin 3.0.4.201108101432-7E37B7HFEHCdSHSV5R_IyJetqA_B ( 3.0.4.201108101432-7E37B7HFEHCdSHSV5R_IyJetqA_B)当前安装的软件:com.aptana.feature.studio.feature.group Pydev 2.2.1.2011071313 (org.python.pydev.feature.feature.group 2.2.1.2011071313)一次只能安装以下之一: 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2.0.0.20110403 (org.python.pydev 2.0.0.20110403)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 ( Pydev 1.5.0.1251989166) Pydev-org.python.pydev开发环境1.5.2.1260362205 (org.python.pydev 1.5.2.1260362205)无法满足依赖关系:发自: Aptana Studio 3插件3.0.4.201108101432-7E37B7HFEHCdSHSV5R_IyJetqA_B (com.aptana.feature.studio.feature.group org.python.pydev To: org.python.pydev.feature.feature.group 2.2.1.2011073123无法满足依赖关系: From: Extensions调试插件2.2.1.2011073123 (com.python.pydev.debug 2.2.1.2011073123) To:捆绑包org.python.pydev 2.2.1.2011073123无法满足依赖关系: From: PyDev for Eclipse2.2.1.2011071313 (org.python.pydev.feature.feature.group 2.2.1.2011071313) To: org.python.pydev 2.2.1.2011071313无法满足依赖关系: From: PyDev对于Eclipse 2.2.1.2011073123 (org.python.pydev.feature.feature.group 2.2.1.2011073123)到: com.python.pydev.debug 2.2.1.2011073123

我该怎么办？

Answer 1

Studio3默认包含PyDev，所以您需要先从当前的Eclipse安装卸载现有的PyDev，然后再安装Studio3插件。

希望这能有所帮助。
