(RuntimeError) could not find schema.ex in any of the sources

hi guys, I am new to elixir, following a tutorial to generate context with “mix phx.gen.schema Blog.Post blog_posts title:string views:integer”, however it return error “(RuntimeError) could not find schema.ex in any of the sources”. I have tried google the error with no luck, much appreciate if anyone can point me to the right direction. Thank you

Can you please post the full error message?

And also please tell us which versions of erlang, elixir, phoenix, ecto and ecto_sql are involved (the latter three by your mix.lock file)
