Django

Question

我正在运行从 AWS 安装 linux 红帽环境。

我已按照所有说明将 sqlite3 升级到“最新”版本。

我是运行ning python 3.9.2（并用 LD_RUN_PATH=/usr/local/lib ./configure 重新编译）和 django 版本 4.

我已经设置了一个虚拟环境来安装和运行 django。我已将激活脚本更改为包含 export LD_LIBRARY_PATH="/usr/local/lib"

运行宁python manage.py runserver，我收到错误django.db.utils.NotSupportedError: deterministic=True requires SQLite 3.8.3 or higher。我已经打开文件 /home/ec2-user/django/django/db/backends/sqlite3/base.py（发生错误的地方），并且在错误行之后包含一个打印语句：

print("**************************\n" +
    str(Database.sqlite_version) +
    "\n" + str(Database.sqlite_version_info) +
    "\n**************************")

返回运行s:

**************************
3.28.0
(3, 28, 0)
**************************
**************************
3.28.0
(3, 28, 0)
**************************

请让我知道需要哪些额外信息。我在 stack 上上下搜索，找不到 pop 的正确解决方案。

提前致谢！

The above exception was the direct cause of the following exception:

Answer 1

目前我能想到的最好办法是进入/home/ec2-user/django/django/db/backends/sqlite3/base.py，将get_new_connection()中的函数变量deterministic=True更改为deterministic=False...

这将消除错误，但似乎是一个超级作弊的解决方案。如果有人有更好的解决方法，请告诉我。

Answer 2

我在 linux Centos7+python3.9.6+Django3.2.5 中遇到了同样的问题。虽然 sqlite3 已更新为最新版本。看来这是没用的。一种解决方案是将数据库从 sqlite3 更改为 pysqlite3。激活virtualenv后，安装pysqlite

pip3 install pysqlite3
pip3 install pysqlite3-binary

并在 base.py

中更改数据库

vim python3.9.6/site-packages/django/db/backends/sqlite3/base.py

# from sqlite3 import dbapi2 as Database # annotation
from pysqlite3 import dbapi2 as Database # import pysqlite3

重新启动 django 服务器，一切正常。

Answer 3

我遇到了和你一样的问题。当我尝试在 Elastic Beanstalk 上部署时。在我的例子中，当我像这样初始化 EB CLI 时使用了 Python 3.8：

eb init -p python-3.8 django-project ⛔

在 64 位 Amazon Linux 2（默认）上运行它不是一个很好的 python 版本。更改为 python-3.7

eb init -p python-3.7 django-project ✅
