简介
:我正在尝试将trac sqlite迁移到postgresql后端,为此我需要psycopg2。在点击了www.initd.org上令人尴尬的咆哮之后,我下载了最新版本并尝试运行
setup.py install
. 这没用,告诉我我需要知道。所以我下载并安装了mingw。
问题
:运行时出现以下错误
setup.py build_ext --compiler=mingw32 install
:
running build_ext

我试过的
-我注意到了-l选项中的正斜杠,所以我在setup.cfg的library_dirs选项中手动输入了postgresql lib目录,但没有结果(调用随后有一个带反斜杠的-l选项,但错误消息保持不变)。
