Errors in Jest

[elado]

When trying to install a version of a package in jest, deasync throws

Assertion failed: (handle->type == UV_TCP || handle->type == UV_TTY ||
 handle->type == UV_NAMED_PIPE), function uv___stream_fd, file 
../deps/uv/src/unix/stream.c, line 1632.

Test code inside jest:

import niv from 'npm-install-version';
const packageName = 'noop2@1';
niv.install(packageName);
const noop = niv.require(packageName);

deasync bug @ abbr/deasync#55

Is there a workaround?

as a side note, had to add node to moduleFileExtensions in jest config
e.g. moduleFileExtensions: ['ts', 'tsx', 'js', 'jsx', 'node'],

Found a workaround: install the package version outside of jest's context, something like:

// package.json
"scripts": {
  "test:prepare": "niv foo@1 && niv foo@2".
  "test": "npm run test:prepare && FOO_VERSION=1 jest && FOO_VERSION=2 jest"
}

This still allows me to require a specific version

require(`foo@${process.env.FOO_VERSION}`)

clearing the cache seems work for me as a work around $ jest --clearCache && jest
