the apm(the package manager of atom) start shell run error

I am dealing with a bug of apm in my osx 10.11 system. When I run 

apm

in my command line, it throw an error because of the wrong file path:

/usr/local/bin/apm: line 32: /Applications/Atom.app/Contents/Resources/app/apm/node_modules/.bin/node: No such file or directory

After checked out, I found that: In the apm shell(/Atom.app/Contents/Resources/app/apm/node_modules/.bin/apm), there is a while loop:

while [ -L "$binDir" ]
do
  binDir=`readlink "$binDir"`
  builtin cd "`dirname "$binDir"`"
  binDir=`basename "$binDir"`
done

It seems like this loop runs only one time on my osx system and runs twice on others, the bug which I have is because of this.

-L checks whether the file is a symbolic link and returns True if so. From man test:

   -L FILE
          FILE exists and is a symbolic link (same as -h)

See an example where we create a file hello and a (soft)link to it called my_link:

$ touch hello
$ ln -s hello my_link
$ [ -L "hello" ] && echo "this is a link" || echo "this is NOT a link"
this is NOT a link
$ [ -L "my_link" ] && echo "this is a link" || echo "this is NOT a link"
this is a link
