unable to test (win 10)

Created a fresh new app and was unable to run “npm test” (Windows 10)

mern init newAPP
cd newApp
npm install

it looks like it tries to run a linux script in (\node_modules.bin\acorn)

the error:

D:\development\newAPP>npm test

> mern-starter@2.0.0 test D:\development\newAPP
> cross-env NODE_ENV=test PORT=8080 MONGO_URL=mongodb://localhost:27017/mern-test node_modules/.bin/nyc node --harmony-proxies node_modules/.bin/ava

To fix this, I removed the npm --harmony-proxies portion from the “test” command in package.json, and added a --serial flag to the end.

package.json:

    "test": "cross-env NODE_ENV=test PORT=8080 MONGO_URL=mongodb://localhost:27017/mern-test node_modules/.bin/nyc node_modules/.bin/ava --serial",

I’m not sure what the purpose is of npm --harmony-proxies in this command; can the maintainer explain it? This --serial seems to be required when performing the testing upon git commit.

At any rate, in Windows this is the reason for the errors: npm is processing the ava (bash) script as Javascript. Hence dirname is undefined. The node_modules/.bin folder actually has two scripts, ava which is bash and ava.cmd which is a DOS batch file; so it is node_modules/.bin/ava.cmd that gets called on Windows using the above configuration.
