Failed to find .env file at default paths: [./.env,./.env.js,./.env.json] code example

Example 1: Failed to find .env file at default paths: [./.env,./.env.js,./.env.json]

Add -f to your package.json file, Ex: env-cmd -f ./config/dev.env nodemon src/index.js

Example 2: Failed to find .env file at default paths: [./.env,./.env.js,./.env.json]

Add -f to your package.json file, Ex: env-cmd -f ./config/dev.env nodemon src/index.js

Example 3: Failed to find .env file at default paths: [./.env,./.env.js,./.env.json]

Add -r since .env is a file and we want to read the content of it.
I also changed the default paths and added some of my paths to work smoothly on the localhost.
If you need to add the local paths then follow {node-modules -> env-cmd -> dist -> get-env-vars}  in here you will get an array of default paths, add your path 
"dev": "env-cmd -r ./src/config nodemon src/index.js" do this way

Example 4: Failed to find .env file at default

You can rename .env.development to just .env and then run env-cmd gatsby develop, this will look for environment variables inside .env file.
