python – 试图写一个cPickle对象,但是得到一个’write’属性类型的错误

TypeError                                 Traceback (most recent call last)
    <ipython-input-4-36ec95de9a5d> in <module>()
     13     all[i] = r.json()
     14 
---> 15 cPickle.dump(all,outfile)

TypeError: argument must have 'write' attribute

这是我按顺序完成的：

outfile = "C:\John\Footy Bants\R COMPLAEX MATHS"

然后,我粘贴了以下代码：

import requests,cPickle,shutil,time

all = {}
errorout = open("errors.log","w")

for i in range(600):
    playerurl = "http://fantasy.premierleague.com/web/api/elements/%s/"
    r = requests.get(playerurl % i)

    # skip non-existent players
    if r.status_code != 200: continue

    all[i] = r.json()

cPickle.dump(all,outfile)

这是原始文章,让您了解我正在尝试实现的目标：
