python之pymongo: ImportError: 没有名为 pymongo 的模块

我使用pip3成功安装了pymongo

Aleeshas-MacBook-Air:project 2 aleesha$ sudo pip3 install pymongo

然后我用 python 编写了一个写入 MongoDB 的测试脚本。但是当我执行它时，出现以下错误:

Aleeshas-MacBook-Air:project 2 aleesha$ python pythonScript.py  
Traceback (most recent call last): 
  File "pythonScript.py", line 5, in <module> 
    from pymongo import MongoClient 
ImportError: No module named pymongo 
Aleeshas-MacBook-Air:project 2 aleesha$ 

Python 版本:Python 3.5.2

路径是这样的:

 >>> import sys 
    >>> sys.path 
    ['', '/Users/aleesha/Documents', '/Library/Frameworks/Python.framework/Versions/3.5/lib/python35.zip', '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5', '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/plat-darwin', '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/lib-dynload', '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages'] 
>>> sys.version 
'3.5.2 (v3.5.2:4def2a2901a5, Jun 26 2016, 10:47:25) \n[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)]' 
>>>  

在谷歌上搜索。在 stackoverflow 上发现了这个问题:ImportError: No module named 'pymongo'然后指向 stackoverflow 上的另一个页面:failure to import pymongo ubuntu

sudo pip uninstall pymongo ==> Succesfully uninstalled 
sudo pip uninstall bson ==> Cannot uninstall requirement bson, not installed 
sudo apt-get remove python-bson ==> sudo: apt-get: command not found 
sudo apt-get remove python-gridfs    # not sure if it's necessary ==> sudo: apt-get: command not found 
sudo pip install pymongo -U ==> successfully installed pymongo 

但是即使在这之后，我也面临着同样的问题。我无法导入 pymongo 模块。

编辑:我正在尝试更多的方法来解决这个问题。使用 IDLE，我可以导入 pymongo 并轻松地将记录插入 MongoDB。

>>> from pymongo import MongoClient 
>>> client = MongoClient() 
>>> db = client.kmp 
>>> db.KMP_DATA.insert_one({"seq" : 1,"data" : "ABCD"}) 
<pymongo.results.InsertOneResult object at 0x1058c8828> 
>>>  

但是我仍然无法从 python 脚本中导入它。

请您参考如下方法:

“pip”或“pip3”与“python”或“python3”不是同一个环境是一个常见问题。为确保您使用与运行时相同的环境进行安装:

python -m pip install pymongo 

或者:

python3 -m pip install pymongo
