Can you please try
echo $MIX_ENV/ as well?
As the files seem to work for us, I’m pretty sure that it is something about your
MIX_ENV environment variable…
The way, how the error message is printed:
.exsCode.LoadError) could not load /Users/htran/Desktop/hello/config/dev ^^^^ ^^^^^^
is very suspicious and makes me wonder why the file ending is printed on the beginning of the line. This is usually the case, when there is some stray
\r in a printed string…
