原位金属匠给模板渲染错误：（未知路径）

Question

我有一个相当大的Metalsmith项目，使用Nunjucks进行模板制作（即使用metalsmith-in-place，使用jstransformer-nunjucks）：

const Metalsmith       = require('metalsmith'),
      inplace          = require('metalsmith-in-place');

Metalsmith(__dirname)
  .metadata(metadata)
  .source('./src')
  .destination('./build')
  .use(inplace({
    engineOptions: {
      root: path.join(__dirname, 'src')
    }
  }))
  .build(function(err) {
    if (err) {
      throw err;
    }
  });

运行构建脚本时，从带有“未知路径”的模板中收到模板错误：

> project@0.4.0 build ~/project
> node build.js

~/project/build.js:155
          throw err;
          ^

我不知道我的许多Nunjucks文件中的哪一个引起了错误。如何获得就位的金属匠给我引起问题的文件的路径？
