Tape: Test fail to run on Windows when using babel

[i2infinity]

FEEL FREE TO CLOSE THIS OUT IF IT IS NOT A TAPE ISSUE

I am using [email protected] npm v3.8.3 and node v4.4.0 on Windows 8.1 and have the following script in my package.json

"test": "babel-node ./node_modules/.bin/tape tests/*.js",

Now when I execute npm run test from my command prompt, I get the following error

C:\Users\user\Documents\GitHub\project\node_modules\.bin\tape:2
basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")
          ^^^^^^^

That stack trace implies it's a babel-node issue - but also, I'm not sure babel-node (a node runner) can be used to run another node runner (tape).

Problem is because, on Windows, ./node_modules/.bin/tape is not a JavaScript file. This is neither a tape concern, nor a babel concern—it's just how npm works.

npm uses the cmd-shim to "link" binaries on Windows since symlinks are not suitable in that case. As a result, ./node_modules/.bin/tape is a shell script.

The fix, in your case, is to not reference anything in .bin as if it were a JS file. Tape, fortunately, has the -r/--require flag, so you can recreate the functionality afforded you by babel-node with the require hook and polyfill:

tape -r babel-register -r babel-polyfill tests/*.js
