Django：“没有名为uuSqlite3的模块”和“找不到满足sqlite3要求的版本”

Question

我正在用运行centos6.1的godaddyslinuxvps上的django框架制作一个站点。我安装了python3.6.9，安装了vitualenv，安装了django，并将sqlite3更新到3.29.0版本。尽管如此，当我运行命令“python3管理.pyrunserver“我得到以下错误：

(djangovenv) [user blackpepperfries]$ python3 manage.py runserver

  File "/usr/local/lib/python3.6/sqlite3/dbapi2.py", line 27, in <module>
    from _sqlite3 import *
ModuleNotFoundError: No module named '_sqlite3'

然后，当我尝试运行“pip3 install sqlite3”作为安全检查时，出现以下错误：

(djangovenv) [user blackpepperfries]$ pip3 install sqlite3
Collecting sqlite3
  ERROR: Could not find a version that satisfies the requirement sqlite3 (from versions: none)
ERROR: No matching distribution found for sqlite3

不知道我哪里出错了。这一切工作在我的本地机器，但一旦我把它移到戈达迪错误开始弹出。你知道吗

Answer 1

您是从源代码构建python安装的吗？如果是这样的话，看起来您在构建SQlite开发包时并没有安装它。你知道吗

确保其已安装（libsqlite3 dev）

并确保 enable-loadable-sqlite-extensions位于python配置路径上
