我有一个错误：

当我在macOS而不是virtualenv中安装psycopg2时，这对我很有帮助：psycopg2

回答@zganger

但是，当我在Virtualenv2.7（venv）中时，什么都不起作用，甚至在那篇文章中也没有答案。我花了一周时间试图解决这个问题，但一点运气都没有。

我不知道我还能做什么。

1. pip install django-toolbelt
2. pip install psycopg2

Answer 1

所以，我已经尽了我所能，我发现我的莫哈韦版本是

10.14.5

这是到2019年7月14日为止的最新版本，但它不起作用。

我已经更新到最新版本了

10.14.6 and Command Line Tools 10.3

它于今天（2019年7月15日）发布，运行完美。

可能是以前的命令行工具或10.14.5版本的Mojave存在问题
