npmrc causes npm to install to home directory instead of nodeenv
Here is what happened when I tried to get eslint installed: 

```
$ pre-commit run --all-files
eslint..............................................................................................................................................................................................................................................................................................................Failed
hookid: eslint

xargs: eslint: No such file or directory
```

Moving .npmrc to nope.npmrc fixed the issue.
