我遇到了这个错误，我有一个用于创建条形图的自定义指令，它从json文件生成。
这是我的代码，我有一个Index.Html页面，其中一个视图根据导航在里面路由

你的html和脚本中缺少一些角度代码。我做了几件事：
<html ng-app="routerApp">添加到html页面var routerApp = angular.module('routerApp', []);添加到js文件我创建了一个PLUNK的结果。与您的代码唯一不同的是，我更容易找到TSV示例文件而不是您在代码中引用的JSON文件。所以，我从d3.json改为d3.tsv，但这在这里并不重要。我希望这会有所帮助。

在整个HTML中都存在无关的，未封闭的和错误的标记，而Angular似乎正在努力解析。我建议您检查HTML的有效性，因为这样可以解决您遇到的问题。
如果你想要一些例子，我可以提供一些，请在评论中告诉我。

之前我遇到过这些问题，而且它与将replace选项设置为true的指令有关。因此，可能需要检查在特定情况下是否确实需要替换选项。
