Where do I begin to troubleshoot this: Error: Cannot find module './task.html'

I am working through the simple-todos Meter.com tutorial:
https://www.meteor.com/tutorials/blaze/update-and-remove

Now I get this error:

Error: Cannot find module './task.html’
W20160804-12:30:16.418(-7)? (STDERR) at Function.require.resolve (packages/modules-runtime/.npm/package/node_modules/install/install.js:101:1)
W20160804-12:30:16.421(-7)? (STDERR) at Module.resolve (packages/modules-runtime/.npm/package/node_modules/install/install.js:57:1)

meteor >
simple-todos >
imports >
ui >
body.html
body.js
task.html
task.js

task.js has this:
import ‘./task.html’;

Why cannot task.html be found?
Thanks.

I’m having a similar problem, but it’s for one of the previous steps where you import ‘./body.html’ and it gives the same error
