注：该错误来自子进程，大概率不是pip本身的问题。

解决方法 #

1. 升级pip及相关工具 #

先确保pip、setuptools和wheel是最新版本，避免因工具版本过低导致兼容性问题：

pip install --upgrade pip setuptools wheel

2. 安装最新版MindsDB #

你尝试安装的23.6.1.1版本可能存在打包缺陷，直接安装最新稳定版：

pip install mindsdb --upgrade

如果需要指定版本，可先确认MindsDB的最新版本号，再执行类似pip install mindsdb==[最新版本号]的命令。

3. 从GitHub源码手动安装 #

如果上述方法无效，直接克隆完整源码包，确保依赖文件完整：

git clone https://github.com/mindsdb/mindsdb.git
cd mindsdb
pip install -r requirements/requirements.txt
pip install .
