Troubleshooting with nodejs and npm

I got error when I tried to install rasa-nlu-trainer
$npm i -g rasa-nlu-trainer

error:

npm http GET https://registry.npmjs.org/express
npm ERR! Error: SSL Error: CERT_UNTRUSTED
npm ERR!     at ClientRequest.<anonymous> (C:\Program Files\nodejs\node_modules\npm\node_modules\request\main.js:409:26)
npm ERR!     at ClientRequest.g (events.js:185:14)
npm ERR!     at ClientRequest.EventEmitter.emit (events.js:88:17)

solution:

You can bypass https using below commands:

npm config set strict-ssl false

Install Python 3 in Ubuntu

if add-apt is not found,

sudo: add-apt-repository: command not found
sudo apt-get install software-properties-common python-software-properties
sudo add-apt-repository ppa:git-core/ppa
sudo apt-get update


sudo add-apt-repository ppa:jonathonf/python-3.6



I don't know my previous post above if its totally working on how to install python 3.6.
But here, I just tested it and obviously it works.

sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update
sudo apt-get install python3.6

Inheriting a view without overriding the original view

the solution is to add

<field name="mode">primary</field> 

that's it! I don't know who created odoo but it's hard to get the right answer because of less documentation.

Setup a vagrant with gui

I have experimented to launch a vagrant using existing VMbox like ubuntu but I was failed to do it. I found this tutorial below.

https://relativkreativ.at/articles/how-to-build-a-vagrant-base-box-from-a-virtualbox-vm

Although, this example is based on centos I'm hoping to manage it in Ubuntu. I got an error in its really frustrating.

So I stop and goes right away to vagrant cloud to find any existing predefined vagrant box.
this one looks promising and will give it a try.

vagrant init igorbrites/ubuntu-trusty64-gui --box-version 0
