我尝试按照命令安装django

 pip install -e django/

我收到以下错误:

django/ should either be a path to a local project or a VCS url beginning with 
    svn+, git+, hg+, or bzr+

我使用Windows 32位

from PIL import Image
import numpy as np 
import matplotlib.pyplot as plt

def threshold(imageArray):
    balanceAr = []
    newAr = imageArray
    for eachRow in imageArray:
        for eachPix in eachRow:
            avgNum = reduce(lambda x, y: x + y, eachPix[:3]) / len(eachPix[:3])
            balanceAr.append(avgNum)
    balance = reduce(lambda x, y: x + y, balanceAr) / len(balanceAr)
    for eachRow in newAr:
        for eachPix in eachRow:
            if reduce(lambda x, y: x + y, eachPix[:3]) / len(eachPix[:3]) > balance:
                eachPix[0] = 255
                eachPix[1] = 255
                eachPix[2] = 255 …
