Bench build error, babel-core module not found

Install / Update
1

Hi there,

i got an error running bench update in master branch:

module.js:471
    throw err;
    ^

Error: Cannot find module 'babel-core'
    at Function.Module._resolveFilename (module.js:469:15)
    at Function.Module._load (module.js:417:25)
    at Module.require (module.js:497:17)
    at require (internal/module.js:20:19)
    at Object.<anonymous> (/home/frappe/frappe-bench/apps/frappe/frappe/build.js:3:15)
    at Module._compile (module.js:570:32)
    at Object.Module._extensions..js (module.js:579:10)
    at Module.load (module.js:487:32)
    at tryModuleLoad (module.js:446:12)
    at Function.Module._load (module.js:438:3)

Could you please double check?

Update:

installed new clean Ubuntu VM 16LTS, then run:

bench get-app erpnext https://github.com/frappe/erpnext

after cloning, it shows error:

module.js:471
    throw err;
    ^

Error: Cannot find module 'babel-core'
    at Function.Module._resolveFilename (module.js:469:15)

    at tryModuleLoad (module.js:446:12)
    at Function.Module._load (module.js:438:3)

then installing babel-core, it asks for less and other …installing all requested packages it rises error:

…and counting lines or error …

It’s really kind of frustrating … Can someone double check this?!

Thx

I can confirm this error. Have the same one on my Debian Jessie box.

I was able to fix this with

npm install babel-preset-es2015

This module was installed on another box where this error doesn’t occour.

Some how this file didn’t run when we install frappe: frappe/install_new_build_system_requirements.py at master · frappe/frappe · GitHub

I have to manual install those packages and it works again,

npm install babel-core less chokidar babel-preset-es2015 babel-preset-es2016 babel-preset-es2017 babel-preset-babili
