我正在尝试安装 sqlalchemy 以与带有 ubuntu 12.04 的 python 3.x 的 mysql 数据库交互，但是当我导入 sqlalchemy 时，它说没有名为 sqlalchemy 的模块。这就是我安装时所做的：

aoi@aoi:~$ sudo apt-get install python3-sqlalchemy
[sudo] password for aoi:

我做错什么了吗？

这让你获得了适用于 python 2.x ubuntu 的 sqlalchemy 版本 0.8.4 在保持软件包最新方面非常慢

sudo apt-get install python3-sqlalchemy

所以对于 Python 3 / Ubuntu 窥视这里是如何安装最新版本的 sqlalchemy

sudo apt-get install python3-pip
# Now you have pip3

sudo apt-get install python3-all-dev
# Required for sqlalchemy's c extensions to be installed

sudo pip3 install SQLAlchemy
# note using pip, not pip3, will install for Python 2.7

:~$ python3
>>> import sqlalchemy
>>> sqlalchemy.__version__
>>> '0.9.8'
>>> print("Who's the man?")
>>> You are baby!
>>> quit()

通过使用apt-get，您已将 sqlalchemy 安装在 Ubuntu 的默认 Python 3 的默认目录中，即 3.2。如果您在目录中搜索，/usr/lib/python3/dist-packages您会找到 sqlalchemy 模块（或只需键入locate sqlalchemy）。但是，这不是自定义 Python 寻找其模块的地方。您需要下载源代码并使用正确的 Python 编译它，例如/opt/python3.3/bin/python3.3 setup.py install在 sqlalchemy 的源目录中。请参阅此处的说明：http: //docs.python.org/3.3/install

似乎python3-sqlalchemy已经过时了。您可以尝试使用pip3来获取最新版本。

sudo pip3 install sqlalchemy

应该做的伎俩。
