Unable to build the plugin locally.

I don't know if I am missing an env file or any step in running the plugin locally. I get the following error when I try to build the plugin. Any help would be appreciated.

TS2403: Subsequent variable declarations must have the same type. Variable 'process' must be of type 'Process', but here has type '{ env: { NODE_ENV: "development" | "production" | undefined; API_ROOT: string | undefined; API_KEY: string | undefined; }; }'.
