我用的是新的macos high sierra 10.13.5。
我首先使用自制软件安装了python3：

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install python

然后我从github克隆了我的python项目存储库，它有一个requirements.txt文件，该文件有以下行：

mysqlclient==1.3.10

然后我创建了一个虚拟env并运行了pip安装：

python3 -m venv venv
pip install -r api/requirements.txt

然后我得到以下错误：

You are using pip version 10.0.1, however version 18.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

在我以前的mac book pro上，我没有这个问题。在那个macbook上，我使用了使用gcc4.2.1的python3.6.5。在这个新的macbook上，我使用了Clang9.1.0（venv）$python3.7.0（默认值，2018年8月22日，15:22:33）[Clang9.1.0（Clang902.0.39.2）]在darwin上
这篇文章是我唯一能做的，似乎相关，但似乎没有什么帮助。。。

任何关于调试的想法都将不胜感激。谢谢。
