Code to reproduce

import ffmpeg from "fluent-ffmpeg";
// or
const ffmpeg = require("fmpeg");

Expected results

Normal initialization.

Observed results

 ERROR  Failed to compile with 1 errors                                                                                                                                                                                     10:10:32 PM

This relative module was not found:

* ./lib-cov/fluent-ffmpeg in ./node_modules/fluent-ffmpeg/index.js
 ERROR  Build failed with errors.
error Command failed with exit code 1.

Process finished with exit code 1

The above occurs despite not installing ffmpeg on my machine, and even if I do, the process.env.FLUENTFFMPEG_COV ternary should return false, but since isn't, the require('./lib/fluent-ffmpeg') won't be called and therefore the code will cause the aforementioned error to be thrown.

Checklist

• [ ] I have read the FAQ
• [ ] I tried the same with command line ffmpeg and it works correctly (hint: if the problem also happens this way, this is an ffmpeg problem and you're not reporting it to the right place)
• [ ] I have included full stderr/stdout output from ffmpeg

I'm 99% certain it's not an issue with fluent-ffmpeg, but rather with Yarn, which I discovered that isn't guaranteed to always add all the files of a given module. I filed an issue on Yarn's repository.
