Do you have a local Babel install? If so, what version?

[sindresorhus]

@TrySound Not a very useful title. Please try harder the next time ;)

[TrySound]

@sindresorhus I just don't know what is the problem :))

  "devDependencies": {
    "ava": "^0.3.0"
  },

and global the same

[forabi]

I have the exact same error on Linux, so apparently it does not have anything to do with Windows.
Here is my devDependencies:

{
    "ava": "^0.3.0",
    "babel": "^5.8.23",
    "babel-runtime": "^5.8.25"
}

My .babelrc

{
  "stage": 1,
  "optional": ["es7.classProperties", "es7.comprehensions"]
}

[TrySound]

@sindresorhus I use npm3. Maybe babel5 doesn't work on it?

[forabi]

@TrySound Well, I thought that was the cause, so I switched to node 0.12 and npm 2, but the issue is still present. So it is not that either.

[uiur]

This might be because babel-plugin-espower does not use a local babel.

https://github.com/sindresorhus/ava/blob/1d5ef4c5f6fcb70f9e90e584dfd08865db1e93b4/lib/babel.js#L12

    plugins: [
        createEspowerPlugin(require('babel-core'), {
            patterns: require('./enhance-assert').PATTERNS
        })
    ]
};

This should be a mistake. I'll create a PR if I can reproduce it.

[uiur]

Reproduced in npm 2.14.2.

package.json

  "devDependencies": {
    "ava": "^0.3.0",
    "babel": "5.8.21",
    "babel-core": "5.8.21"
  }

test.js

import test from 'ava';

test((t) => {
  t.pass();
  t.end();
});

@sindresorhus I'm so sorry that I've missed your ping.

@uiureo

I'll create a PR if I can reproduce it.

Thanks a lot!

[uiur]

@TrySound @forabi The patch has been merged into master. Could you try it?

[TrySound]

@uiureo Seems like it works. Great! @sindresorhus Need to make hot patch. When you can release?
