One true development environment fails when directory has spaces in it

Describe the bug
Issue occurs when attempting to run tools/setup.py in a directory that has spaces in it.

Directory is as follows: /Users/jessewang/Documents/Personal Code/popcode
Example Stacktrace:

tools/setup.py
 * Install prebuilt node (10.16.2) ..... done.
bash: line 1: /Users/jessewang/Documents/Personal: No such file or directory
bash: line 1: /Users/jessewang/Documents/Personal: No such file or directory

error popcode@0.9.0: The engine "node" is incompatible with this module. Expected version "~10.16.2". Got "8.12.0"
error Found incompatible module.

To Reproduce

1. Store the popcode repo in a folder that has spaces in it.
2. Run tools/setup.py

Expected behavior
tools/setup.py successfully runs and sets the node environment to the correct version.

• OS: iOS
• Version: Current master branch

Comienza con tools/setup.py y reproduce el fallo colocando el repositorio popcode en una ruta que contenga espacios; después, ejecuta el comando de configuración. Comprueba cómo el script invoca bash y configura la versión precompilada de Node; la tarea está completada cuando la configuración finaliza correctamente desde esa ruta y selecciona Node 10.16.2 como se espera.
