为什么我不能安装mysqlclient == 1.3.10

问题描述

我正在使用新的MacOS High Sierra 10.13.5。

我首先使用Homebrew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，该存储库有一个requirements.txt文件，其中包含以下行：

mysqlclient==1.3.10 

然后，我创建了一个虚拟环境并运行pip安装：

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

然后出现以下错误：

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.

在我的旧Macbook Pro上，我没有这个问题。 在那本Macbook上，我有使用GCC 4.2.1的python 3.6.5。 在这台新的Macbook上，我有python 3.7，使用lang 9.1.0（venv）$ python Python 3.7.0（默认，Aug 22 2018，15:22:33）[dar 9.1.0（clang-902.0.39.2）]

本文是我所能想到的惟一一件事，但似乎并没有太大帮助。

任何调试的想法将不胜感激。 谢谢。
