Python引入 requests 会报UnicodeDecodeError

你要放代码啊，不然不好说清 --------------------------------------------------- 提示已经很明显了，它说ascii转换出问题。 肯定是你把某些内容，放进一个文件(或变量)里，然后那个文件是ascii编码的，所以就报错了。 --------------------------------------------------

无源码，无真相

[谭十二]

下面是源码QAQ

# -*- coding:utf-8 -*-

from lxml import etree
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
import requests

url = "https://movie.douban.com/top250"

html = requests.get(url).text
selector = etree.HTML(html)

movies = selector.xpath('//div[@class="info"]/div[@class="bd"]/div[@class="star"]/span[@class="rating_num"]/text()')

print movies
for each in movies:
    print each

引用 4 楼 Thoremp 的回复:

@sanGuo_u 大神你好,源码见楼上,报错时提示 import requests 这一行 出错,以前没有这种情况,后来有的

我用给你给的代码试了试，没有报错 这个是运行结果

你说 import requests ，这个报错。是不是说没有这个模块？ 如果没有，就pip install requests

[sanGuo_uu]

抱歉，这问题我解决不了

[风华渐逝]

可以装个PyCharm,里面有个package管理功能，看看 requests 是否有被正确安装

[zangree]

我也遇见这个问题，import cryptography.x508，会报同样的错误

[zangree]

我的问题解决了，因为环境变量中有中文字符。

楼主这个问题解决了吗我跟你遇到一样的问题
