vscode导入requests遇到问题

1.vscode 安装python库的时候，报：bash: pip: command not found

使用 python -m pip 命令
python3 -m pip install requests

2. timeout：
   pip._vendor.urllib3.exceptions.ReadTimeoutError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Read timed out.

解决：
换国内镜像
python3 -m pip install requests -i https://pypi.tuna.tsinghua.edu.cn/simple
