导入错误：导入错误：无法从“bson.py3compat”导入名称“abc”

Question

How can i solve this error. It will generate while running program.

from bson import ObjectId
class JSONEncoder(json.JSONEncoder):
    def default(self, o):
        if isinstance(o, ObjectId):
            return str(o)
        return json.JSONEncoder.default(self, o)

Answer 1

That's most likely due to version mismatches.

This worked for me:

pip uninstall bson
pip uninstall pymongo
pip install pymongo
