无法在Mac OS上运行jupyter（给出pysqlite2错误）

Posted 2021-04-11

我在mac os sierra安装了anaconda。简单的python脚本运行正常。但是，当我尝试运行jupyter-notebook时，它失败了。

错误消息如下：

Traceback (most recent call last):
  File "/Users/poudel/anaconda3/lib/python3.6/site-packages/notebook/services/sessions/sessionmanager.py", line 10, in <module>
    import sqlite3

    from sqlite3.dbapi2 import *
  File "/Users/poudel/anaconda3/lib/python3.6/sqlite3/dbapi2.py", line 27, in <module>
    from _sqlite3 import *

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/Users/poudel/anaconda3/bin/jupyter-notebook", line 7, in <module>
    from notebook.notebookapp import main

    from pysqlite2 import dbapi2 as sqlite3
ModuleNotFoundError: No module named 'pysqlite2'

我检查了dylib文件，但它就在那里。这有什么不对？

Bhishan:ls /usr/lib/libsqlite3.dylib 
/usr/lib/libsqlite3.dylib*

类似的问题：

No module named _sqlite3

但他们没有解决我的问题。

答案

你的问题很可能是由于几个python环境造成的。检查这个question。 this question也许相关。

还尝试使用conda查看所有已安装的软件包。
