Question

对于那些有类似问题的人，我已经在stackoverflow上做了一些事情，但是这个错误刚刚出现。

我甚至尝试重启，命令+ R，然后设置csrutil disable。

然后重新启动，运行python manage.py makemigrations。

看来它在/ usr / local / lib /中看起来是'libpq.5.dylib'，但它在我的计算机上存在于/usr/lib/libpq.5.6.dylib。

哪个位置正确？我应该把它复制一遍吗？

错误：

settings.py

}

从sqlite3切换到Django App的postgres - 2）：未加载库：/usr/local/lib/libpq.5.dylib
