Couldn't find preset “es2015” relative to directory “web/static/js”

Question

I\'m trying to build a vagrant server for dabbling with elixir and phoenix, but after installing all requirements and dependencies, and on running mix phoenix.server

Answer 1

I see that there is already an accepted answer here. I just encountered the exact same error, and tried the solution Chris posted above. It did not work for me, but based on the github issue link Chris posted above, I found a solution that worked for me.

I found that you don't necessarily need to be using node v5.0+. I am using node 4.4.3 LTS, and things are working.

npm install --save-dev babel-preset-es2015

Answer 2

Please see the fix here: https://github.com/phoenixframework/phoenix/issues/1410

1. Upgrade to node >= v5.0.0
2. npm cache clean
3. cd my_app
4. rm -rf node_modules/
5. npm install
6. mix phoenix.server

Answer 3

My solution which is great works:

.pipe(babel({
    presets: [require('babel-preset-es2015')]
}))

Thanks!

Answer 4

The accepted answer did not work for me.

I had to remove the .babelrc in the parents directories of my app.
