我该如何解决这个问题呢？

Answer 1

不确定这是否能解决此问题，但一种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，您也可以手动安装PyDev，方法是下载压缩文件并将其解压缩到eclipse/dropins文件夹。

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

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

希望这些方法中的一个可以解决这个问题。:)

Answer 2

在使用Ubuntu时，我在安装所有版本的PyDev时都遇到了问题，即使是在使用PyDev网站上提供的压缩文件的时候也是如此，但这里有一个解决方案可以让它正常工作。

最新版本的Eclipse可以使用带有"http://pydev.org/updates“的Eclipse特性来完成PyDev安装，但即使已安装的PyDev也不会执行任何操作。(如果您处于这种情况，可以跳到步骤2 )较早版本的Eclipse将显示上述错误。然而，如果你遵循这些说明，旧的(至少可以追溯到Ubuntu软件中心的版本，3.7.2)和新版本都可以很好地使用PyDev 3.0+。

第1步：

转到(PyDev website)并下载适用于Pydev3.0或更高版本的压缩文件。

导航到~/.eclipse/org.eclipse.platform_VERSION/ (在Ubuntu中，不确定Eclipse文件夹在Windows中的位置)，然后创建一个名为"dropins“的文件夹。将下载的zip文件的内容复制到这个新文件夹中。

第2步：

现在将安装PyDev，但在下载Java7之前不会执行任何操作，因此您需要在终端中键入以下命令：

sudo add-apt-repository ppa:webupd8team/java

sudo apt-get update

sudo apt-get install oracle-java7-installer

sudo apt-get install oracle-java7-set-default

如果你使用的是WindowsOracle7，你应该可以从网站下载并安装Java7，到此为止。

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，您需要在32位系统上的终端中键入以下内容：

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

或者在64位系统上执行以下操作：

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

PyDev 3.0+现在应该可以完全在Eclipse中工作了！

Answer 3

pydev网站要求eclipse的版本应该是3.8/4.2 (JUNO)或更高版本。

我遇到了同样的问题，更新了eclipse，这个问题就消失了。

如果安装程序能提供更具描述性的报告，那就更好了。
