ImportError：無法導入名稱“ binary_type”

Question

我已經安裝了BSON庫以將字符串轉換為MongoDB ObjectId，但是當我嘗試使用該庫時，會出現以下情況：

    Traceback (most recent call last):
  File "search.py", line 7, in <module>
    from pymongo.mongo_client import MongoClient
  File "/home/user/anaconda3/lib/python3.6/site-packages/pymongo/__init__.py", line 90, in <module>
    from pymongo.common import (MIN_SUPPORTED_WIRE_VERSION,
  File "/home/user/anaconda3/lib/python3.6/site-packages/pymongo/common.py", line 21, in <module>
    from pymongo.auth import MECHANISMS
  File "/home/user/anaconda3/lib/python3.6/site-packages/pymongo/auth.py", line 33, in <module>
    from bson.binary import Binary
  File "/home/user/anaconda3/lib/python3.6/site-packages/bson/binary.py", line 21, in <module>
    from bson.py3compat import PY3, binary_type
ImportError: cannot import name 'binary_type'

pip還會安裝py3compat，但其中沒有“ binary_type”。 任何想法如何解決這個問題？

我看到此錯誤，並通過安裝最新版本的pymongo 。
