关于pip install psycopg2、python-ldap出错的问题

出现Running setup.py install for psycopg2 … error错误

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install python-psycopg2
sudo apt-get install libpq-dev
pip3 install psycopg2

如果出现Building wheel for python-ldap (setup.py) … error错误

解决方法：

sudo apt-get install libsasl2-dev python-dev libldap2-dev libssl-dev
