我最近尝试安装以下所述的NetBeans插件：https://blogs.oracle.com/geertjan/entry/python_in_netbeans_ide_8
然而，当我现在尝试启动NetBeans时，我得到一个可怕的错误，就像这样：
Warning - could not install some modules: Java Source Queries - None of the modules providing the capability org.netbeans.modules.java.source.queries.spi.QueriesController could be installed.

我在OS X上运行它。
我删除了目录/Users/<MyUser>/Library/Application Support/NetBeans和/Users/<MyUser>/Library/Caches/NetBeans，正如我在几个地方看到的那样，但我仍然收到同样的错误。
这完全使我瘫痪，阻止我做任何工作，我不知道发生了什么或如何解决它。
任何帮助都将受到大力赞赏。

遇到同样的僵局，我在netbeans.org和其他网站上下搜索，提供了我的日志错误https://netbeans.org/bugzilla/show_bug.cgi?id=248986和https://netbeans.org/bugzilla/show_bug.cgi?id=248291#c5
我详尽地搜索了esp。我的％appdata％/ Netbeans中的jar和xml文件，按最新修改时间排序， 并找到如下文件：
C：\用户\主\应用程序数据\漫游\的NetBeans \ 8.0 \模块 ORG-netbeans的模块-JIRA-rest.jar ORG-netbeans的模块-JIRA-xmlrpc.jar ORG-netbeans的模块-scanondemand.jar 等
但删除它们，或者使用以前的版本将它们交换出去并没有帮助。
看到没有真正的解决方案甚至回滚失败的更新，至少让我的Netbeans再次启动，我在其他地方安装了夜间版本http://bits.netbeans.org/download/trunk/nightly/latest/进行比较（在虚拟机上，我的＆＃34;备用＆ ＃34; PC）。
继续将全新安装与我破损的安装进行比较。 我的损坏的％appdata％没有变化似乎允许NB启动。
最后，我比较了系统范围的安装文件夹，发现在我的破坏副本中，不仅许多.jar文件的大小不同，而且还有一些文件完全丢失，包括这一点在我得到的启动错误中广泛存在：
C：\ PROGRAMFILES \的NetBeans \平台\芯\ ORG-openide-文件系统-compat8.jar
这是最强烈的暗示，很容易成为＆＃34;修复＆＃34; ....
好像永远不允许https://forums.netbeans.org/posting.php?mode=quote&p=79922中的某些来源进入更新中心。 （http://deadlock.netbeans.org/hudson/job/nbms-and-javadoc/lastStableBuild/artifact/nbbuild/nbms/updates.xml.gz在我的情况下....虽然依赖链完全不清楚。）
最终，我将整个C：\ ProgramFiles \ NetBeans \文件夹从全新安装覆盖到损坏的文件夹，并成功启动。
需要一些更新，然后再重新启动。 我的大多数设置仍然存在，黑暗主题，最近的文件列表等。 除了Ruby on Rails插件，它仍然被禁用，我仍在尝试重新添加和启用它，因为它甚至阻止了我的ROR项目的开放。
总而言之，可怕的部分解决方法可能相当于使用开发版重新安装Netbeans（以前我在8.0.2上）。

请注意，您不应将开发插件（如Python或Scan-on-Demand）安装到生产安装中。这样做很可能会破坏你的安装，你会很难过。
如果要使用开发插件，请使用NetBeans的开发分发 IDE bits.netbeans.org/download/trunk/nightly/latest /
目前是专为IDE 8.0.2制作的 Python插件;有关这方面的更多信息，请访问Oracle的Geertjan博客：https://blogs.oracle.com/geertjan/entry/python_in_netbeans_ide_81
