python安装PySide2模块报错

报错为:ERROR: THESE PACKAGES DO NOT MATCH THE HASHES FROM THE REQUIREMENTS FILE. If you have updated the package versions, please update the hashes. Otherwise, examine the package contents carefully; someone may have tampered with them.

解决办法：出现这种情况一般为网速较慢，但是模块较大下载不完全。加上延时命令即可解决

pip install --upgrade --default-timeout=10000 PySide2
