Good day:
I've just installed Babel Preset-ENV through NPM and getting this issue:
[nodemon] starting `babel-node server.js server.js`
/home/vagrant/api/node_modules/babel-core/lib/transformation/file/options/option-manager.js:328
throw e;
^

My Package.JSON is the following:
{
"name": "api",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "nodemon -L server.js --ignore 'db/schema.json' --exec babel-node server.js"
},
"author": "",
"license": "ISC",
"dependencies": {
"@babel/core": "^7.0.0-beta.32",
"@babel/preset-env": "^7.0.0-beta.32",
"babel-core": "^6.26.0",
"express": "^4.16.2",
"express-graphql": "^0.6.11",
"express-oauth-server": "^2.0.0",

"password-hash": "^1.2.2",
"react-relay": "^1.4.1"
},
"devDependencies": {
"babel-cli": "^6.26.0"
}
}
And also my .babelrc is this:
vagrant@vagrant-ubuntu-trusty-64:~/api$ cat .babelrc
{
"presets": [
["@babel/preset-env", {
"targets": {
"node": "current"
}
}]
]
}
Before the upgrade I was using stage-0 and es2015 presets that were working however, after the upgrade this has been buggy. Note, my NPM version is 4.6.1.
Thanks.
