python - 安装 psycopg2 osx 10.12 python 3.5.2 - psycopg2 的构建轮失败

Question

我在 OSX 中安装 psycopg2 时遇到了很大的问题。使用自制软件安装 Postgresql 9.5.4_1 后，我尝试在我的虚拟环境中安装 psycopg2:pip 安装 psycopg2

我还使用 PATH=$PATH:/usr/local/Cellar/postgresql/9.5.4_1/bin/pg_config 添加了 pg_config 到我的路径


执行后我收到一些错误，包括:

  ld: library not found for -lssl


 clang: error: linker command failed with exit code 1 (use -v to see invocation)
  error: command 'clang' failed with exit status 1

和

Failed building wheel for psycopg2

和

Command "/Users/*username*/.virtualenvs/report/bin/python3.5 -u -c "import setuptools, tokenize;__file__='/private/var/folders/9p/3_wdgjzd03d6bw1p_c9rrt6c0000gp/T/pip-build-cuplxne2/psycopg2/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /var/folders/9p/3_wdgjzd03d6bw1p_c9rrt6c0000gp/T/pip-8gbk007q-record/install-record.txt --single-version-externally-managed --compile --install-headers /Users/*username*/.virtualenvs/report/bin/../include/site/python3.5/psycopg2" failed with error code 1 in /private/var/folders/9p/3_wdgjzd03d6bw1p_c9rrt6c0000gp/T/pip-build-cuplxne2/psycopg2/

尝试从源代码构建会导致类似的错误...

我的 macosx sierra 之路

全局安装psycopg2，然后在virtualenv中使用

pip3 install psycopg2
workon my_env #i use virtualenvwrapper
toggleglobalsitepackages #Enable global site-packages

在我的例子中，psycopg2 通常作为全局包安装，但没有安装在 virtualenv 中
