A further clarification: When I move to the “Stateful components” section and run a compile with “iex -S mix”, the compile works. When I then try “mix phx.server” i get the same error as shown below. Interestingly, when I then went back to the stateless directory (where I had originally tried the “mix phx.server” and got the error below, I now got the same error when running “iex -S mix”
When attempting this, the server crashes with an error about @assign content not being available in the eex template. I have diffed all the files created following the book text with the ones in your code zip, but see no differences. Interestingly, the code in the “stateless_components” directory of the zip doesn’t compile either. I’ve copied the two sets of errors below.
I’ve moved on and I’m no longer trying to resolve this. Perhaps I have done something in error that I can’t see myself. But perhaps there is an error in the book’s code. Debugging this is beyond me.
Error when I attempt to compile the code in your zip file (downloaded today) under stateless_components:
