Ansible lineinfile duplicates lines - 


 - vars:    npm:       npm_global: "{{ ansible_env.home }}/.npm-global"   - name: update bashrc npm    lineinfile: >    dest={{ project.shell_rc_file }}    regexp='export path={{ npm.npm_global }}/bin:$path'    line='export path={{ npm.npm_global }}/bin:$path'    state=present    backup=yes    create=yes
