运行python3 virtualenv时使用pip3 vs pip有什么区别

Question

I am running python3 inside a virtualenv which I created as follows

==> python3 -m venv venv

==> source venv/bin/activate

==> python
Python 3.6.5 (default, Apr 25 2018, 14:23:58) 
[GCC 4.2.1 Compatible Apple LLVM 9.1.0 (clang-902.0.39.1)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

My web-app has a requirements file with the python package dependencies

What is the difference between using pip3 vs pip to install the dependencies

ie

==> pip3 install -r requirements

vs

==> pip install -r requirements

Answer 1

pip2 is python2 and pip3 is python3. Use the whereis pip command to determine where the executables are located, but if you are in a python3 virtualenv, pip is most certainly equivalent to pip3 .
