Netbeans 中的错误：“找不到 HTML5 的 HtmlParser 实现”

当我在 Netbeans 中打开一个文件时，我Please wait...在编辑器窗口的第一行看到了一个。

屏幕底部还出现一个异常图标，上面写着：

A org.netbeans.modules.parsing.spi.ParseException exception has occurred.
However, the system should continue working without further problems.
Click Show Details for the stack trace.

如果我点击“显示更多详细信息”，我会得到以下信息：

我正在使用原装的 NetBeans IDE 7.0.1，它可以直接从 Ubuntu 12.04 存储库获取。

答案1

我的 php 应用程序也遇到了类似的问题；它显示“请等待...”在页面顶部，并且不允许我正确编辑文件。

我意识到 NetBeans 认为该项目是 HTML5 格式的，而 NetBeans 7.0.1 不支持这种格式，因此我单击了“请稍候...”并选择使用旧版本的 HTML 作为项目的默认设置。瞧，马上就成功了！

答案2

这是 Ubuntu 存储库（NetBeans 7.0.1）中 Netbeans 版本的一个错误。

直接从安装较新版本https://netbeans.org/downloads/并且它可以正常工作。
