我通过Node + Express渲染Nunjucks。
我有很多观点，突然之间我的一个观点就是在下面的堆栈跟踪中抛出错误。
如何找出错误源自哪个模板或辅助/宏？

答案 0 :(得分：1)
正如Aikon Mogwai在评论中所建议的那样，这是关于在node_modules/nunjucks/src/environment.js中添加控制台日志记录的全部内容。
对于观看者来说，最好在第console.log(err, _Obj3)行547（this.rootRenderFunc(this.env, context, frame, globalRuntime, function (err, res) {内的捕获内容）
对于.njk中的错误，最好在console.log(this); 526内的_proto3.render = function render(ctx, parentFrame, cb) {内进行filename
记录的对象将包含以下有用属性
tmplStr - ＆gt;导致错误的文件的绝对路径export const routing: ModuleWithProviders = RouterModule.forRoot([
{
path: '',
component: MainComponent,
children: [
{ path: '', redirectTo: 'notes', pathMatch: 'full'},
{
path: 'notes',
loadChildren: './notes-page/notes-page.module#NotesPageModule'
}
]
}
]);
- ＆gt;它可以在错误之前解析的文件的所有内容
