错误：这些软件包不匹配需求文件中的哈希值。更新Django时

Question

我有Django 2.2.7，现在我想安装Django 3.0.2。我读到我需要运行命令pip install -U Django来更新它，但是当我尝试它时会显示此错误消息

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.
