      warning: missing parentheses for expression following "do:" keyword. Parentheses are required to solve ambiguity inside keywords.

      This error happens when you have function calls without parentheses inside keywords. For example:

          function(arg, one: nested_call a, b, c)
          function(arg, one: if expr, do: :this, else: :that)

      In the examples above, we don't know if the arguments "b" and "c" apply to the function "function" or "nested_call". Or if the keywords "do" and "else" apply to the function "function" or "if". You can solve this by explicitly adding parentheses:

          function(arg, one: if(expr, do: :this, else: :that))
          function(arg, one: nested_call(a, b, c))

could not compile dependency :ecto, "mix compile" failed. Errors may have been logged above. You can recompile this dependency with "mix deps.compile ecto --force", update it with "mix deps.update ecto" or clean it with "mix deps.clean ecto"

I had make steps:

  1. mix ecto.setup
  2. mix compile
  3. mix deps.clean ecto
  4. mix deps.get
  5. mix deps.compile ecto

but still not working and showing error like above
