    Hint: You might be running an invalid version of NPM.

    Command "/www/sentry/bin/python -c "import setuptools, tokenize; __file__='/www/sentry/sentry/setup.py'; exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" develop --no-deps" failed with error code 1 in /www/sentry/sentry
    

I had tried npm@5.0.0 npm@4.1 npm@2.11.2 all did't work


Answer: What you might try is this to see if you get a better error:

  * Pull down the Sentry source code
  * Run "npm install" from the Sentry root directory

We require Node 0.10.x or newer, but it should run on the latest versions as
well. I believe we test on 0.10 and 0.12 locally.
