在 virtualenv 中安装 psycopg2(Ubuntu 10.04，Python 2.5) [英] Installing psycopg2 in virtualenv (Ubuntu 10.04, Python 2.5)

问题描述

我在 virtualenv 中安装 psycopg2 时遇到问题.

I had problems installing psycopg2 in a virtualenv.

我尝试了不同的解释:http://www.saltycrane.com/blog/2009/07/using-psycopg2-virtualenv-ubuntu-jaunty/

我尝试的最后一件事是...
我用 -p python2.5 --no-site-packages
创建了一个 virtualenv我安装了 libpq-dev:apt-get install libpq-dev

The last thing I tried is this...
I created a virtualenv with -p python2.5 --no-site-packages
I installed libpq-dev: apt-get install libpq-dev

在 virtualenv 中，我这样做了:easy_install -i http://downloads.egenix.com/python/index/ucs4/ egenix-mx-base

In the virtualenv, I did this: easy_install -i http://downloads.egenix.com/python/index/ucs4/ egenix-mx-base

然后当我尝试 pip install psycopg2==2.0.7 时，我得到这个错误:

Then when I tried pip install psycopg2==2.0.7, I got this error:

Installing collected packages: psycopg2

有没有人知道如何解决这个问题?
谢谢.

Does anyone have any idea how to solve that?
Thanks.

推荐答案

来自 python-list:

From python-list:

迪兹:安装 python-dev-package.它包含 Python.h 文件，其中上面的错误信息很清楚说.通常，这是一个好主意搜索包描述丢失的 debian/ubuntu 软件包头文件以了解要安装的内容.

Diez: Install the python-dev-package. It contains the Python.h file, which the above error message pretty clearly says. Usually, it's a good idea to search package descriptions of debian/ubuntu packages for missing header files to know what to install.

帕斯卡:它已经安装了；至少对于Python 2.6，也不确定它是否适合蟒蛇 2.5.python2.5-dev 不可用但是python-old-doctools 似乎取代了它.

Pascal: It's already installed; at least for Python 2.6, nor sure it's correct for Python 2.5. python2.5-dev is not available but python-old-doctools seems to replace it.

迪兹:它是 100% 不 正确的蟒蛇2.5.如错误消息所示- 它不见了.如果某处不可用，您应该考虑构建python自己，如果你必须使用 2.5.

Diez: It is 100% not correct for python2.5. As the error message shows - it's missing. If it's not available somewhere, you should consider building python yourself, if you have to use 2.5.

亚历克斯:Ubuntu 10.04 没有完整的Python 2.5 打包，证明缺少python2.5-dev.你需要使用 Python 2.6 或者如果你绝对必须使用 Python 2.5 从源，尝试 Debian 软件包或切换发行版.python-old-doctools 没有替换python-dev，看起来像准备保留一些乳胶工具工作.

Alex: Ubuntu 10.04 doesn't have a full Python 2.5 packaged, as evidenced by the lack of python2.5-dev. You need to use Python 2.6 or if you absolutely must use Python 2.5 build it from source, try a Debian package or switch distro. python-old-doctools does not replace python- dev, it looks like it was bodged to keep some latex tools working.

Pascal: 我终于创建了一个 virtualenv使用 Python 2.6 一切顺利(使用最新版本的 psycopg2).

Pascal: I finally created a virtualenv with Python 2.6 and everything went fine (with the latest version of psycopg2).
