pipも同様にする

[vagrant@localhost ~]$ ls -l /bin/pip*
-rwxr-xr-x. 1 root root 278 Oct 17 13:23 /bin/pip
-rwxr-xr-x. 1 root root 280 Oct 17 13:23 /bin/pip2
-rwxr-xr-x. 1 root root 284 Oct 17 13:23 /bin/pip2.7
-rwxr-xr-x. 1 root root 370 Jan 19  2017 /bin/pip3.6

[vagrant@localhost ~]$ sudo unlink /bin/pip
[vagrant@localhost ~]$ sudo ln -s /bin/pip3.6 /bin/pip

pip-toolsを入れるには、pipのアップグレードも必要

[vagrant@localhost ~]$ sudo pip install --upgrade pip
[vagrant@localhost ~]$ sudo pip install pip-tools
