[英]Python 3.6.3 unable to import _sqlite3 to run a SQlite db with sqlalchemy
I'm running my Fast API project with pipenv and I use Python 3.6.3 as the interpreter.我正在使用 pipenv 运行我的 Fast API 项目,并使用 Python 3.6.3 作为解释器。 For production I use a postgres db which works fine.
对于生产,我使用了一个工作正常的 postgres db。 Now I want to test my api with pytest and sqlite.
现在我想用 pytest 和 sqlite 测试我的 api。
Therefore I changed the db connection setup:因此我更改了数据库连接设置:
engine = create_engine("sqlite:///./test.db")
SessionLocal = sessionmaker(autocommit=False, autoflush=False, bind=engine)
Base = declarative_base()
db = SessionLocal()
I also tried the connection string from the official docs from sqlalchemy:我还尝试了 sqlalchemy 官方文档中的连接字符串:
engine = create_engine('sqlite://')
engine = create_engine('sqlite://')
when I run my test , I get the following error:当我运行测试时,出现以下错误:
engine = create_engine("sqlite:///./test.db")

from _sqlite3 import *
E ModuleNotFoundError: No module named '_sqlite3'
I have seen in the source code that the error causing module has the following note:我在源代码中看到导致错误的模块有以下注释:
pysqlite2/dbapi2.py: the DB-API 2.0 interface

Here the error is cause by这里的错误是由
from _sqlite3 import *
where _sqlite is not found.其中 _sqlite 未找到。 I had a look at the
我看了看
dbapi2.py file from pysqlite3.
来自 pysqlite3 的 dbapi2.py 文件。 Here sqlite is imported without the "_".
这里的 sqlite 是在没有“_”的情况下导入的。 So I thought since python3 the pysqlite3 file should be inbuilt in python.
所以我认为从 python3 开始,pysqlite3 文件应该内置在 python 中。
Is there a way to change the pysqlite2 to 3?有没有办法将pysqlite2更改为3? I've read about installing pysqlite3, but this did not change anything in my case.
我读过关于安装 pysqlite3 的文章,但这对我来说没有任何改变。
I also tried to update from python 3.6.13 to 3.6.3 as 3.6 is mandatory.我还尝试从 python 3.6.13 更新到 3.6.3,因为 3.6 是强制性的。 This also did not change the behaviour.
这也没有改变行为。
