Yeah, spaces are hell in paths in the Posix/Linux kind of world.

What you need is to "protect" the spaces with \ or have them inside a quoted string.
Also, items in a path need to be separated by : and not ; ....

This mostly has to do with understanding how strings, quoting, etc., work in
the Unix world and for bash in particular.  Over time I have developed methods
that work with these things that have space in them. For example, to add something
to the end of PATH:

PATH="${PATH}:/my/new/thing"

Here the quotes are important!  And they need to be " quotes not ' quotes!
( ' quotes would not allow ${PATH} to be expanded, while " quotes do allow that.)
Etc.
