psycopg2无法在Mojave的virtualenv 2.7中安装-macOS-10.14.5

Question

我遇到此错误：

loc_ref.append(from_loc + [user_says])

当我在macOS中而不是virtualenv中安装psycopg2时-这对我有帮助： psycopg2 sierra

@zganger的答案

但是当我使用virtualenv 2.7（venv）时-没有任何效果，即使在该帖子中也没有任何答案。我试图解决这个问题一周了，根本没有运气。

不确定我还能做什么。

创建virtualenv并仅运行这些命令时，两者都无法在psycopg2上运行，如果我安装了任何其他软件包，则除了psycopg2以外，其他所有功能都可以正常工作。

Answer 1

所以，我尽了一切努力，发现我的Mojave版本是

10.14.5

那是截止到2019年7月14日的最新版本，它不起作用。

我已更新到最新版本

10.14.6 and Command Line Tools 10.3

已于今天（2019年7月15日）发布，并且运行良好。

以前的命令行工具或Mojave的10.14.5版本可能有问题

此更新有效：
