I was getting the error this error:

KeyError: ‘\n\n’

when trying to do a str.format(*vals) in python

the issue was that the str, had some {} as part of the template, to fix this I just double the brackets {{}}

The next command helps you to create a simple http server to test anything fast, or use that location and their resources with a different port.
Just navigate in the command line to the location and type the next:

python -m SimpleHTTPServer [port]

Fixing: Error: Couldn’t find preset “latest” relative to directory

Add the babel-preset-latest to the node_modules of the project directory with –save-dev option, in example:
npm install –save-dev babel-preset-latest

PD. This issue came up when configuring webpack on a project recently created from scratch, and configured the babel-loader with the latest as preset.
