我该怎么解决？

Answer 1

pydev站点声明eclipse的版本应该是3.8/4.2（JUNO）及以上版本。

我遇到了同样的问题，更新了eclipse，问题就消失了。

安装程序提供的更具描述性的报告会更好。

Answer 2

在使用Ubuntu时，我在安装3.0版以后的所有PyDev版本时遇到了问题，甚至在使用PyDev网站上提供的zip文件一段时间时也遇到了问题，但下面是让它正常工作的解决方案。

最新版本的Eclipse可以使用带有“http://pydev.org/updates”的Eclipse安装功能来完成PyDev的安装，但是即使安装了PyDev也不会做任何事情。（如果您在这种情况下，可以跳到步骤2）旧版本的Eclipse将显示上述错误。但是，如果遵循这些说明，旧版本（至少可以追溯到Ubuntu软件中心3.7.2的版本）和新版本都可以完美地使用PyDev 3.0+。

步骤1：

转到（PyDev website）并下载Pydev 3.0或更高版本的zip文件。

导航到~/.eclipse/org.eclipse.platformVERSION/（在Ubuntu中，不确定eclipse文件夹在Windows中的位置）并创建一个名为“dropins”的文件夹。将下载的zip文件的内容复制到此新文件夹。

第2步：

PyDev现在将被安装，但在下载Java 7之前不会执行任何操作，因此需要在终端中键入以下命令：

sudo add apt repository ppa:webupd8team/java

sudo apt get更新

sudo apt get install oracle-java7-installer安装程序

sudo apt get安装oracle-java7-set-default

如果您使用的是Windows，那么您可能只需从Oracle网站下载并安装Java 7就可以了。

第3步：

现在将安装Java 7，但Eclipse可能不再启动。如果是这种情况，则需要在32位系统的终端中键入以下内容：

ln-s/usr/lib/jni/lib swt-*~/.swt/lib/linux/x86/

或在64位系统上执行以下操作：

ln-s/usr/lib/jni/lib swt-*~/.swt/lib/linux/x86_64/

PyDev 3.0+现在应该可以在Eclipse中完全工作了！

Answer 3

不确定这是否能解决问题，但一个解决方法可能是在选择要安装的PyDev版本的“安装”对话框中取消选中“仅显示可用软件的最新版本”。

或者，可以通过下载zip文件并将其解压缩到eclipse/dropins文件夹来手动安装PyDev。

您可以在此处找到PyDev的最新版本： http://sourceforge.net/projects/pydev/files/

第二种解决方案如PyDev手册所述： http://pydev.org/manual_101_install.html

希望其中一种方法可以解决这个问题。：）
