Nothing to do

我正在尝试在我的virtualenv中安装psycopg2以将django与postgresql数据库连接。

在Fedora 19和postgresql-9.2中，pg_config的路径是：

/usr/pgsql-9.2/bin

在Fedora 20中，此目录不存在。

但是pg_config可以在/usr/bin/pg_config中找到。

尝试安装psycopg2：

 $ export PATH=$PATH:/usr/bin; pip install psycopg2
Downloading/unpacking psycopg2
  Downloading psycopg2-2.5.2.tar.gz (685kB): 685kB downloaded
  Running setup.py egg_info for package psycopg2

感谢您的帮助。

Answer 1

您缺少python3包含文件

./psycopg/psycopg.h:30:20: fatal error: Python.h: No such file or directory

您可以在python3-devel包中找到它们。

Answer 2

安装python3-devel软件包以使其正常工作

sudo dnf install python3-devel

如果它工作正常或者它需要libpq-fe.h文件，那么使用以下命令安装它：

sudo dnf install postgresql-devel

Answer 3

如其他答案中所示，这是由于没有正确的Python＆＃34; devel＆＃34;包安装。在CentOS上，Python＆＃34; devel＆＃34; rpm包使用限定版本进行编号。例如，在撰写本文时，当前版本是：

对于epel存储库

python34-devel

python36u-devel用于ius存储库

示例Yum命令（假设已配置EPEL repository）：

sudo yum install python34-devel

Answer 4

在 Ubuntu 上。我用以下方法解决了这个问题：

sudo apt-get install libpq-dev

Psycopg2无法在python 3上安装，pip发出致命错误
