缺少模块

Question

try:
    import json, time, os, re, io
    from PIL import Image
    from urllib.parse import urlencode
    import requests, base58
    from BeautifulSoup import BeautifulSoup
except:
    print('ERROR:: missing module(s)')
    exit()

这是脚本，我安装了BeautifulSoup，请求，枕头和base58，我得到了ERROR:: missing module(s)
