python - 导入错误 : No module named '_sqlite3' error- Underscore relevance?

Question

我正在使用 Python3.4，我最近从 python 3.3.2 升级。

我正在按照这些说明安装 newspaper，这是一个 python 库/工具。

https://github.com/codelucas/newspaper

执行此命令后出现错误:

curl https://raw.githubusercontent.com/codelucas/newspaper/master/download_corpora.py | python3

注意:我已经 在上面的命令中还指定了python3.4我得到相同/以下输出/错误:

import sqlite3

    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'

    from _sqlite3 import *
ImportError: No module named '_sqlite3'

所以我查看了/usr/local/lib/python3.4/sqlite3/dbapi2.py

并且此脚本确实尝试从 _sqilte3 导入:

from _sqlite3 import *

我删除了下划线并再次尝试了原来的 curl 命令，但这会导致不同的错误，所以我推断这不是答案。

有人知道这里会发生什么吗？

Answer 1

sqlite3 是 python 模块(用 python 编写)来包装 _sqlite3(一个 c 模块)，使它看起来更像 pythonic。

显然你缺少二进制模块，所以你不能从那里导入。更改导入字符串会给您带来很多错误，因为这些模块实际上是不同的。尝试重新安装 python，至少对我来说 _sqlite3 二进制模块属于 python 本身。
