Cant start new phoenix project

My phoenix project is broken, cant even start it… I’ve tried removing _build, mix clean, redownloading deps, another elixir version and various permutations of the things mentioned… still fails. Any ideas? The project is like 10 minutes old so I wonder what caused this mayhem.

The thing to try first here is always rm -rf _build deps . Give that a shot and see if it helps!

3

I tried that and various other things like I mentioned in the post. Tried it again for good measure, still same problem.

have you upgraded the phx.new generator?
The command is:

mix archive.install hex phx_new
5

It was generated with 1.7.6 to unblock myself I updated it to 1.7.7 and generated a new project that works.

The project generated with 1.7.6 also worked at first until it broke down like that.

I’m creating a new project also and removed/added mix mix local.hex --force, but I can’t install the new version:

mix archive.install hex phx_new

even changing from different Elixir versions didnt help (1.14.0, 1.15.0, 1.15.5)
