导入错误：没有名为'_sqlite3'错误的模块 - 下划线相关性？

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报纸，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
  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'

  File "/usr/local/lib/python3.4/sqlite3/dbapi2.py", line 27, in <module>
    from _sqlite3 import *
ImportError: No module named '_sqlite3'

所以我看了一下/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始的 curl 命令，但这会导致不同的错误，所以我推断这不是答案。

有谁知道这里可能发生了什么？

sqlite3 是 python 模块(用 python 编写(，用于包装_sqlite3(C 模块(以使其看起来更像 python。

显然您缺少二进制模块，因此无法从那里导入。更改导入字符串会给您带来许多错误，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，_sqlite3二进制模块归 python 本身所有。
