Delete `node_modules` and try again. Looks like there was a network issue during installation. ---

Something is odd still if it tries to download [https://github.com/nlohmann/json/releases/download/v3.9.1/include.zip](https://github.com/nlohmann/json/releases/download/v3.9.1/include.zip) and says “Remote end closed connection without response”. Not sure how to help, but you can try to download the file directly and see if you get any errors that way. ---
