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

最佳答案
您缺少python3包含文件
./psycopg/psycopg.h:30:20: fatal error: Python.h: No such file or directory
您可能可以在
python3-devel 包中找到它们。
关于pip - Psycopg2 无法在 python 3 上安装，pip 发出 fatal error ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/21650567/
