报错代码中关键词是 time out，尝试在搜索引擎中查找解决方法，找到3个解决方法：
方案1：
pip install --default-timeout=1000 --no-cache-dir -r requirements.txt
方案2：
pip --default-timeout=100 install gevent
方案3：
替换Pip下载源：
- 临时修改，只有安装 pollow 时使用制定源
pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple pillow
- 永久修改
Linux下，修改 ~/.pip/pip.conf (没有就创建一个)， 修改 index-url至tuna，内容如下：
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
windows下，直接在user目录中创建一个pip目录，如：C:\Users\xx\pip，新建文件pip.ini，内容如下:
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
尝试使用第2种方案解决了问题。
