我读了一些不鼓励使用DYLD_LIBRARY_PATH的文章,因为动态库的路径应该使用-install_name,@ aptath和@loader_path来修复.

在制作在Linux和Mac OS X上运行的程序方面,Mac OS X的DYLD_LIBRARY_PATH正好与Linux的LD_LIBRARY_PATH完全相同.而且,我们可以(几乎)共享同一个没有-install_name和@rpath的make文件.

• 在Mac OS X上使用DYLD_LIBRARY_PATH可以吗？
• 当二进制文件找不到动态库时,Mac OS X的动态库搜索算法是什么？当前目录 - > DYLD_LIBRARY_PATH目录......？

我尝试psycopg2使用virtualenv 安装pip,编译看起来没问题,它说"成功安装了psycopg2",但是当我尝试在python解释器中导入它时(在virtualenv中),它表示错误:

  File "<stdin>", line 1, in <module>
  File "/Users/me/sites/env/trackmap/lib/python2.7/site-packages/psycopg2/__init__.py", line 67, in <module>
    from psycopg2._psycopg import BINARY, NUMBER, STRING, DATETIME, ROWID
ImportError: dlopen(/Users/me/sites/env/trackmap/lib/python2.7/site-packages/psycopg2/_psycopg.so, 2): Library not loaded: libssl.dylib
  Referenced from: /Users/me/sites/env/trackmap/lib/python2.7/site-packages/psycopg2/_psycopg.so
  Reason: Incompatible library version: _psycopg.so requires version 1.0.0 or later, but libssl.0.9.8.dylib provides version 0.9.8

问题是我pip在几周之前使用我的其他虚拟环境成功安装它,就像几个星期前一样,让它postgresql在我的Mac上工作.我想知道这是否是编译器的问题？我shortens from 64-bit to 32-bit在安装psycopg2时看到了一些警告.我的编译器是i686-apple-darwin11-llvm-gcc-4.2mac os x lion上的默认编译器.

我看到几个与psycopg2安装相关的帖子,但大多数都是通过安装在虚拟环境中解决的.那么......有人能给我一个建议吗？谢谢!非常感谢.

ps如果你需要安装psycopg2的编译日志,请告诉我,我没有在这里粘贴,因为它太长了.

我正在遵循Heroku的教程来部署Django应用程序:http://devcenter.heroku.com/articles/django#prerequisites.

一切正常,直到我到达这一部分:

$ pip install Django psycopg2

我可以自己安装Django,但问题是psycopg2.

我一直收到这个错误:

ld: library not found for -lpq

collect2: ld returned 1 exit status

ld: library not found for -lpq

collect2: ld returned 1 exit status

我在我的机器上安装了PostgreSQL 9.1.

另外,在输出中,有这样的一堆行:

我正在尝试创建一个指向/ usr/lib的符号链接,但我似乎没有权限,包含在root中.系统返回不允许操作.

有了优胜美地,我工作得很好,但是随着El Capitan的破产:

谁知道我能做什么？

我正试图让Django在OS X Mavericks上运行,我遇到了一堆错误,最新的方式就是在运行python manage.py runserver时看看是否一切正常,我得到这个错误,我相信这意味着它错过了的libssl:

ImportError:dlopen(/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/psycopg2/_psycopg.so,2):未加载库:@loader_path /../ lib/libssl. 1.0.0.dylib引用自:/ Library/Frameworks/Python.framework/Version/1.7/lib/python2.7/site-packages/psycopg2/_psycopg.so原因:未找到图像

我已经将Python升级到2.7.6,补丁处理了一些小牛队的怪癖.

有任何想法吗？
