I am having a similar problem. These are my attempts:

The Emacs mode uses the bin/tern server, ...

If I open up the package (C-h P tern RET etc.), and do a word search
in "tern.el" for /bin, it seems the package will only look for
"/bin/tern".

I will try a shortcut. From "/usr/local/bin/tern" to "/bin". But this
does not work. By the way, "/usr/local/bin/tern" is itself a shortcut
to "/usr/local/lib/node_modules/tern/bin/tern".

Everything looks tricky to me. There is a line in tern.el which speaks
of a location "../bin/". Relative to where? The tern file also has
similar, where it mentions a "../lib/tern". But where I think that
should be, I only find a "lib/tern.js". Very confused, I don't really
know how this stuff works.

Personally, I installed tern.el from elpa, so it is in my
"~/.emacs.d/elpa/". I don't know if this is compatible with the
author's setup.

By the way, I used =sudo apt-get install npm= and =sudo npm install -g
tern= to install tern.

If these locations (of tern) are the issue, is there some way to make
this work by exposing variables for the paths in the Emacs init file?
