无法在 Mac OS X 10.7 上的 virtualenv 中使用 pip 安装 psycopg2 [英] Can't install psycopg2 with pip in virtualenv on Mac OS X 10.7
问题描述
我正在按照 Heroku 的教程部署 Django 应用程序:http://devcenter.heroku.com/articles/django#先决条件.
I am following Heroku's tutorial to deploy a Django app: http://devcenter.heroku.com/articles/django#prerequisites.
一切正常,直到我到达这部分:
Everything is working fine until I get to this part:
$ pip install Django psycopg2
我可以自己安装 Django,但问题是使用 psycopg2.
I can install Django by itself, but the probelm is with psycopg2.
我不断收到此错误:
ld: library not found for -lpq
collect2: ld returned 1 exit status
ld: library not found for -lpq
collect2: ld returned 1 exit status
lipo: can't open input file: /var/folders/_4/p6l0y0t51hd4xbq7llbyshmw0000gn/T//cc0L10mI.out (No such file or directory)
error: command 'gcc-4.2' failed with exit status 1
我已经在我的机器上安装了 PostgreSQL 9.1.
I've installed PostgreSQL 9.1 on my machine.
另外,在输出中,有一堆这样的行:
Also, in the output, there are bunch of lines like this:
gcc-4.2 -fno-strict-aliasing -fno-common -dynamic -isysroot /Developer/SDKs/MacOSX10.6.sdk -arch i386 -arch x86_64 -g -O2 -DNDEBUG -g -O3 -DPSYCOPG_DEFAULT_PYDATETIME=1 -DPSYCOPG_VERSION="2.4.4 (dt dec pq3 ext)" -DPG_VERSION_HEX=0x090004 -DPSYCOPG_EXTENSIONS=1 -DPSYCOPG_NEW_BOOLEAN=1 -DHAVE_PQFREEMEM=1 -I/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -I. -I/usr/include -I/usr/include/postgresql/server -c psycopg/typecast.c -o build/temp.macosx-10.6-intel-2.7/psycopg/typecast.o
我不太确定这是什么意思,但我确实注意到其中包含macosx-10.6",所以我想知道这是否可能是问题所在?我在 10.7.
I'm not really sure what it means, but I do notice that it has "macosx-10.6" in it so I'm wondering if that could be the issue? I'm on 10.7.
预先感谢您的帮助.
