Compatibility with pnpm

pnpm is a fast implementation of npm install with the following features:

• much faster dependencies installation
• important disk usage reduction
• installation progress is displayed very nicely

Unfortunately, ava is not compatible with it as pnpm use symlinks to install the deps which makes ava complain:

$ npm test
> @ test issue-ava-pnpm
> ava

WARNING: `npm link ava` and the `--preserve-symlink` flag are incompatible. We have detected that AVA is linked via `npm link`, and that you are using either an early version of Node 6, or the `--preserve-symlink` flag. This breaks AVA. You should upgrade to Node 6.2.0+, avoid the `--preserve-symlink` flag, or avoid using `npm link ava`.

It would be very nice if it could be fixed 😄

@zkochan I only want what’s best for pnpm because it’s much nicer to use than npm 😃

Adding a property to ava’s package.json looks like the best approach but it’s not up to me (@sindresorhus, what’s your opinion on this?).

I don’t know whether this was fixed on ava’s end but the latest version of pnpm does not require --preserve-symlinks. It is used by default for now, but you can set the preserve-symlinks config to false by running npm config set preserve-symlinks false and ava should work fine.

In case of questions feel free to open an issue on pnpm, or write me on gitter/twitter
