Question

我在我的rhel 5上安装了django 1.4。默认情况下，rhel 5中有python 2.4但是要使用django 1.4我手动安装了python 2.7.3 开发服务器运行正常，但是当我创建一个新项目并将settings.py文件更改为：

之后

'ENGINE'：'django.db.backends.sqlite3'， 'NAME'：'/ home / oracle /Desktop / test1 / my.db'

现在，当我给出python2.7 manage.py syncdb命令时，我收到错误：

Traceback (most recent call last):

django.core.exceptions.ImproperlyConfigured: Error loading either

_sqlite3

请建议出路？

Answer 1

您可能还手动编译了python而没有安装sqlite开发库

所以，做

sudo apt-get install libsqlite3-dev libsqlite3

然后，重新安装python

输入

进行测试

python
>>> import sqlite3

Answer 2

在django.db.backends.sqlite3，它会尝试

try:
    try:
        from pysqlite2 import dbapi2 as Database
    except ImportError:
        from sqlite3 import dbapi2 as Database
except ImportError as exc:
    from django.core.exceptions import ImproperlyConfigured
    raise ImproperlyConfigured("Error loading either pysqlite2 or sqlite3 modules (tried in that order): %s" % exc)

因此未安装名为 sqlite3 或 pysqlite2 的模块之一。尝试安装它们

$ pip install sqlite3 # or pysqlite2

<强>更新

sqlite3和pysqlite2是Python的一部分，因此这两个软件包不再位于PyPi中。

Answer 3

当我尝试运行Django开发服务器时，我得到了非常相似的错误消息：

ImproperlyConfigured: Error loading either pysqlite2 or sqlite3 modules (tried in that order): dlopen(/Users/Rubinous/Projects/Jiiri2/jiiri_venv/lib/python2.7/lib-dynload/_sqlite3.so, 2): Library not loaded: /usr/local/opt/sqlite/lib/libsqlite3.0.8.6.dylib
Referenced from: /Users/Rubinous/Projects/Jiiri2/jiiri_venv/lib/python2.7/lib-dynload/_sqlite3.so
Reason: image not found

我通过使用pysqlite安装pip install pysqlite Python模块解决了这个问题。

Answer 4

在MacOSX 10.9（Mavericks）上，我必须运行此命令：

CPPFLAGS=-I/usr/local/opt/sqlite/include; LDFLAGS=-L/usr/local/opt/sqlite/lib; pip install pysqlite

我用homebrew安装sqlite3。

brew update; brew install sqlite

Answer 5

这就是我为了让它发挥作用所做的。

我正在使用安装了python 2.7.5的pythonbrew（使用pip）。

我首先做了Zubair（上图）所说的并运行了这个命令：

sudo apt-get install libsqlite3-dev

然后我运行了这个命令：

pip install pysqlite

这解决了数据库问题，我在运行时得到了确认：

python manager.py syncdb

Answer 6

从版本2.5开始，

sqlite3是Python的一部分。安装此lib：

sudo apt-get install libsqlite3-dev

或者您也可以尝试安装Python-dev软件包。

Answer 7

我在Red Hat上从源代码构建的python 2.6.8遇到了同样的问题（但这可能适用于其他操作系统上的其他版本）。

我的问题是通过安装sqlite-devel（Red Hat）之前配置和构建python（或在构建目录中执行config.status --recheck，然后是make和{ {1}}。

Answer 8

FreeBSD10 ：对于 python3.5

pkg install py35-sqlite3

Answer 9

MordicusEtCubitus的答案是正确的。还不能成为新手吗？

只需添加到您的答案中，在fedora（23）上运行以下命令即可安装。

sudo dnf install libsqlite3x-devel libsqlite3x

Django - 没有名为_sqlite3的模块
