sqlite3的是不是能夠在Python導入3

Question

SQLite是工作正常使用Python 2.7，但是當我試圖在Python導入此3提示錯誤

> Traceback (most recent call last): File "dbConnection.py", line 1, 
> in <module> 
>  import sqlite3 File "/usr/local/lib/python3.4/sqlite3/__init__.py", line 23, in <module> 
>  from sqlite3.dbapi2 import * File "/usr/local/lib/python3.4/sqlite3/dbapi2.py", line 27, in <module> 
>  from _sqlite3 import * ImportError: No module named '_sqlite3' 

刪除這個錯誤我試圖重新安裝sqlite3通過

sudo apt-get install sqlite3 

但它說包已經存在。在那之後我將嘗試

pip3 install sqlite3 

安裝它，但同時再次安裝提示錯誤

Could not find a version that satisfies the requirement sqlite3 (from versions:) 
No matching distribution found for sqlite3 

，但我的連接工作正常... 現在我應該怎麼做，我能在python 3中導入sqlite3？

Answer 1

sqlite3是可選標準庫的一部分。它是在編譯和安裝Python 3時編譯的，但只有在正確的sqlite3包含文件（開發標頭）可用時纔會編譯。

如果你自己編譯並安裝了Python 3，安裝依賴（libsqlite3-dev或sqlite-devel或相似的，這取決於你的Linux發行版，例如），然後重新編譯和重新安裝Python 3

外部，圖書館保持爲pysqlite;但是that release doesn't support Python 3。即使那樣，要安裝它，你仍然需要那些sqlite開發文件，並且你需要將它移植到Python 3.你可能只需重新編譯Python 3.
