pip에 설치된 Python 스크립트가 모든 사람에 대해 실행되지 않는 이유는 무엇입니까?

존재하다내 Vagrant 인스턴스:

vagrant@archlinux:~$ sudo pip2 install vcard
Downloading/unpacking vcard
  Downloading vcard-0.9.tar.gz
  Running setup.py (path:/tmp/pip_build_root/vcard/setup.py) egg_info for package vcard

Requirement already satisfied (use --upgrade to upgrade): isodate in /usr/lib/python2.7/site-packages (from vcard)
Installing collected packages: vcard
  Running setup.py install for vcard

    Installing vcard script to /usr/bin
Successfully installed vcard
Cleaning up...
vagrant@archlinux:~$ ls -l $(which vcard)
which: no vcard in (/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl)
total 0
vagrant@archlinux:~$ ls -l /usr/bin/vcard
-rwxr-x--- 1 root root 286 Nov  9 10:42 /usr/bin/vcard

/usr/bin/vcard루트로만 실행할 수 있습니다. 무엇을 제공합니까?

이는 제한적인 umask로 인해 발생한 것 같습니다.

vagrant@archlinux:~$ sudo bash -c umask
0027

vagrant 및 root 에 설정되어 있는 것으로 나타났습니다 .profile.알 수 없는 이유:

vagrant@archlinux:~$ sudo grep ^umask /root/.profile
umask 027
vagrant@archlinux:~$ grep ^umask ~/.profile
