Question

我在OSX中安装psycopg2时遇到很大麻烦。使用自制软件安装Postgresql 9.5.4_1后，我试图在我的虚拟环境中安装psycopg2： pip install psycopg2

我还使用PATH=$PATH:/usr/local/Cellar/postgresql/9.5.4_1/bin/pg_config

将pg_config添加到我的路径中

一旦执行，我会收到一些错误，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

并且

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......

Answer 1

我对macosx sierra的态度

全局安装psycopg2，然后在virtualenv

中使用它

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

在我的情况下，psycopg2通常作为全局包安装，但未在virtualenv中安装

Answer 2

Mine破坏了Sierra 10.12.2更新。重新安装/更新了正确安装的命令行工具和psycopg2。

xcode-select --install

Answer 3

这似乎是Homebrew对OSX sierra更新的问题。我能够通过卸载并重新安装python 3.5和postgresql with homebrew ，然后再次尝试安装psycopg2来解决这个问题。
