  2. From within VSCode View -> Command Palette, then type shell and run install 'code' command in PATH
# Setup a virtual env
virtualenv env
. env/bin/activate

# Install pyls
pip install .

# Install the vscode-client extension
cd vscode-client
npm install .

# Run VSCode which is configured to use pyls
# See the bottom of vscode-client/src/extension.ts for info
npm run vscode -- $PWD/../

Then to debug, click View -> Output and in the dropdown will be pyls. To refresh VSCode, press Cmd + r
