python - Netbeans 8.0 启动报错

Question

我最近尝试安装 NetBeans 插件，描述如下:https://blogs.oracle.com/geertjan/entry/python_in_netbeans_ide_8

但是，当我现在尝试启动 NetBeans 时，出现了一个可怕的错误，它是这样开始的:

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.

然后继续页面和页面和页面。

我在 OS X 上运行它。

我已经删除了目录 /Users/<MyUser>/Library/Application Support/NetBeans和 /Users/<MyUser>/Library/Caches/NetBeans ，正如我在一些地方看到的那样，但我仍然收到相同的错误。

这让我完全瘫痪并阻止我做任何工作，我不知道发生了什么或如何解决它。

我们将不胜感激任何帮助。

Answer 1

遇到同样的僵局，我上下搜索了 netbeans.org 和其他网站，提供了我的错误日志 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:\Users\master\AppData\Roaming\NetBeans\8.0\modules org-netbeans-modules-jira-rest.jar org-netbeans-modules-jira-xmlrpc.jar org-netbeans-modules-scanondemand.jar 等

但是删除它们，或者用以前的版本替换它们，都没有帮助。

看到没有真正的解决方案来回滚失败的更新，至少为了让我的 Netbeans 重新启动，我安装了夜间构建 http://bits.netbeans.org/download/trunk/nightly/latest/在其他地方进行比较(在虚拟机上，我的“备用”PC)。

继续比较全新安装和损坏的安装。 对我损坏的 %appdata% 的任何更改似乎都不允许 NB 启动。

最后，我比较了系统范围的安装文件夹，发现在我损坏的副本中，不仅许多 .jar 文件大小不同，而且有些文件完全丢失，包括这个与我遇到的启动错误广泛相关的文件:

C:\ProgramFiles\NetBeans\platform\core\org-openide-filesystems-compat8.jar

这是最强烈的暗示，不会轻易“修复”......

好像是https://forums.netbeans.org/posting.php?mode=quote&p=79922中的一些来源永远不应该被允许进入更新中心。 (在我的例子中是 http://deadlock.netbeans.org/hudson/job/nbms-and-javadoc/lastStableBuild/artifact/nbbuild/nbms/updates.xml.gz……尽管依赖链完全不清楚。)

最终我把全新安装的C:\ProgramFiles\NetBeans\文件夹全部覆盖到坏掉的，启动成功。

它需要一些更新，然后再重新启动。 我的大部分设置仍然存在，深色主题、最近的文件列表等。 除了 Ruby on Rails 插件，它一直处于禁用状态，我仍在尝试重新添加和启用它，因为它甚至阻止了我的 ROR 项目的打开。

总而言之，糟糕的部分解决方法可能相当于使用开发版重新安装 Netbeans(之前我使用的是 8.0.2)。
