Aptana 3.4.2安装PyDev 2.7.0。

如何安装PyDev 2.8.2？

我去了Help>Install New Software并添加了http://pydev.org/updates站点，选中了“仅显示最新版本的…”和“按类别分组项目”，按下“下一步”，得到以下错误：

接下来，我转到我的AppData\Local\Aptana Studio 3\plugins目录&用2.8.2集替换了所有的PyDev 2.7.0文件。当我打开Aptana时，我得到了一个Could not open the editor: No editor descriptor for id org.python.pydev.editor.PythonEditor错误。

我听说只有在安装Aptana时才能执行PyDev，所以我尝试提取Aptana安装文件Aptana_Studio_3_Setup_3.4.2.exe并用2.8.2集替换这些PyDev 2.7.0文件，但是我找不到任何看起来熟悉的东西，所以我离开了。

Answer 1

Aptana安装了自己的pydev，因为它的内部依赖关系，所以更新它是不安全的，您必须等待Aptana团队发布新版本的软件。如果您希望更加灵活，并更新所需的所有部件，只需使用普通Eclipse和您需要安装的所有插件(pydev、html、javascript、css等等)。

Answer 2

有一个黑客可以这么做：https://stackoverflow.com/a/25971061/398491

基本上，您可以安装一个测试版的Aptana，以便卸载PyDev，然后通过更新站点安装最新的PyDev。
