如何在python控制台中使用pip安装本地包

Question

I am not sure if this is because I work in my company and there is a proxy, I cannot set the environment variable. So, I cannot use pip install in CMD. I try to download the package, to my local machine, and install it using the method from Installing python module within code . But I failed. Here is my code:

import pip
pip.main(['install','h://feng.officeworks/mixed/myPython/numpy-1.12.0'])

This does not work for me, I have the following information:

Invalid requirement: 'h://feng.officeworks/mixed/myPython/numpy'
Traceback (most recent call last):

I am using windows 10, Python 3.6.0, Pycharm 2016.3.2. pip is already installed with Python

Also, because I do not have access to environment variable, I cannot set the path to Python. So I cannot use the orders like python or pip in a window terminal. So I need to use a function in python console.

Thanks a lot for the answers. I also tried to go to C:\\Users\\fchen4\\AppData\\Local\\Programs\\Python\\Python36-32\\Scripts, then use

pip install h://mypath/numpy. 

I already unpack numpy here. It does not work. The information shown in PowerShell is like:

    .... (There are too much here so I ignore it.)

Anyone could please tell me how to install a local package using pip or anything else in python console?

Install a particular source archive file:

pip install ./downloads/SomePackage-1.0.4.tar.gz

Also you can download the module source distribution and install it, unpack the archive into a similarly-named directory: foo-1.0 . Additionally, the distribution will contain a setup script setup.py ,and then run this command from a terminal:

python setup.py install

If you want to install package within code,try this:

import os
os.system("pip2.7 install foo")

Or

import subprocess
subprocess.call(['pip', 'install', foo])

Hope this helps.
