问无法使用pip安装py3exiv2？

EN

sudo apt-get install build-essential python-all-dev libexiv2-dev libboost-python-dev

pip3 install py3exiv2

Need to set user-data & meta-data to prep the Linux2 distro. (see AWS doco)
VirtualBox nic to Bridge and active nic
storage to use new seed.iso


update /etc/ssh/sshd_config  
    PermitRootLogin yes
 and 
    PasswordAuthentication yes
    #PasswordAuthentication no

Check disk space needed  !!  need about 4GB 
         Add & mount another vol if needed

~~~~~~~~~~~~~
If using Virtual Box  you can set up folder / directory sharing as follows

For AWS Linux2  (Q1 2018) It found that the CentOS7 process worked perfectly.  (watch the wrong form quote marks)
