1. TypeError: Object of type ‘bytes’ is not JSON serializable

 with open(filename, rb ) as fb: image base64.b64encode(fb.read()) data_dict { img_base64 : image.decode( utf-8 ) data json.dumps(data_dict) req request.Request(URL, data bytes(data, encoding utf-8 ), headers HEADERS) res request.urlopen(req) content res.read() content json.loads(content)

2._csv.Error: iterator should return strings, not bytes (did you open the file in text mode?)

#! -*- coding: utf-8 -*-from contextlib import closingfrom urllib import parseimport codecsimport csvimport requestsURL xxxxxx url URL ? parse.urlencode(query)with closing(requests.get(url, headers HEADERS, stream True)) as r: reader csv.reader(codecs.iterdecode(r.iter_lines(), gbk )) for row in reader: print(row)

3. ImportError: No module named _sqlite3

python3环境import sqlite3时报错 错误原因时安装python时找不到sqlite3安装目录 可以在python的安装目录的setup.py中看到

sqlite_inc_paths [

tar -xzvf xxxx.gzcd xxxx./configure --prefix /usr/localmake -jmake install 

所以需要重新编译安装sqlite3后 再重新编译安装python.
sqlite3下载 https://www.sqlite.org/download.html
