无法在 MacOS 上安装 mysqlclient

Question

我一直在尝试将 mysql 集成到我的 Flask 项目中。我最近迁移到 MacOS，因此很难安装依赖项。我尝试使用 pip 下载 mysql 客户端，但出现以下错误

Answer 1

该文档帮助了我： https: //github.com/PyMySQL/mysqlclient

我按照下面的部分进行操作。

macOS（自制）

安装 MySQL 和 mysqlclient：

# Assume you are activating Python 3 venv
$ brew install mysql pkg-config
$ pip install mysqlclient

如果你不想安装MySQL服务器，你可以使用mysql-client来代替：

# Assume you are activating Python 3 venv
$ brew install mysql-client pkg-config
$ export PKG_CONFIG_PATH="/opt/homebrew/opt/mysql-client/lib/pkgconfig"
$ pip install mysqlclient

我使用的是 MariaDB docker 镜像，所以我不想在我的 Mac 上安装 mysql，所以我遵循了第二条指令。
