Shell-mode emacs shows npm sets characters weird

Question

Shell mode cannot display the process npm install; He shows:

[?25h[1A[?25l[0G
[?25h[1A[?25l[0G
[?25h[1A[?25l[0G
[?25h[1A[?25l[0G
[?25h[1A[?25l[0G
[?25h[1A[?25l[0G
etc

What can be done about this? I really like it shell-modeotherwise.

          (lambda () (setenv "PAGER" "cat")))
