# 安装chardet
python3 -m pip install chardet
# 查看chardet安装路径
python3 -m pip show chardet
...
Location: /Users/d2l/Library/Python/3.9/lib/python/site-packages
...
# 拷贝chardet包到miniconda目录下
cp -R ~/Library/Python/3.9/lib/python/site-packages/chardet ~/miniconda3/lib/python3.10/site-packages/
# 再次执行d2l环境创建命令，顺利完成
conda create --name d2l python=3.9 -y
