Question

我试图在Mac上本地使用psycopg2。它安装得很好，至少没有错误，但是当我导入它时会收到一条错误消息。

我已经看到了数十个具有类似问题和解决方案的线程，这些线程大量变化，对于这样一个常见模块而言似乎过分。

任何人都可以帮忙吗？

我可以看到一些来自不同应用程序的副本。我假设我可以复制其中一个。上面的消息告诉我什么是引用此文件，但它们并没有告诉我他们期望找到它。如果我知道它应该去哪里，我会尝试这个。

bash-3.2# find . -name "libssl.1.0.0.dylib"
./Library/Application Support/Fitbit Connect/libssl.1.0.0.dylib
./Library/PostgreSQL/9.5/lib/libssl.1.0.0.dylib

谢谢你们。

@maxymoo我接受了你的建议。我已经安装了anaconda2。安装更新了我的路径include / anaconda / bin。

然后使用导航器我安装了pyscopg2。现在我可以在shebang中使用它，我的脚本执行得很好，我可以导入这个模块。
