/bin/python3: No module named pip

环境：centos7

I installed Python 3.4 on CentOS 7.3:

1.   sudo yum install epel-release
2.   sudo yum install python34.x86_64

There was python 2 installed before under

1.   type python
2.   python is hashed (/bin/python)

So version 3 is under python3:

1.   type python3
2.   python3 is hashed (/bin/python3)

On Windows, I have version 3.5 and the way I install packages is:

python -m pip install <package_name>

 

So I tried the same on CentOS but calling python3 instead of python:

1.   python3 -m pip install psycopg2
2.   /bin/python3: No module named pip

How do I install or enable pip in Python 3.4 on CentOS so that I can install packages?

使用如下方法解决：

1.   sudo yum install python34-setuptools
2.   sudo easy_install-3.4 pip
