Speed Bumps

• Setting up and using virtualenv using virtualenvwrapper-win in conjunction with Sublime can be a bit confusing
• Not using virtualenvwrapper-win AKA virtualenvwrapper command and windows CMD prompt can lead to undesired results setting up virtualenv for use inside Sublime.
  • Option: Use git bash for running virtualenv commands
  • I found that using Windows CMD prompt and virtualenvwrapper command work best
• Project setup that works best for me
  • create project directory
  • create requirements.txt in project directory and include psycopg2==2.7.x.x (.x.x = current version) in its contents
  • mkvirtualenv -a S:\Udemy\python-postgresql\section10-python-web-apis\project -r S:\Udemy\python-postgresql\section10-python-web-apis\project\requirements.txt udemy-postgresql-section10
  • After setting up sublime-text-virtualenv, open the package manager * ctrl+shift+,, p, search "Virtualenv: Activate" then select the option udemy-postgresql-section10
