Here appears Could not install packages due to an EnvironmentError: [WinError 5] Access denied

• Here we will use the '--user' permission to download
• Re-type pip install -U pip setuptools --user in Anaconda, and the Script file'E:\Anaconda\Scripts\pip-script.py' is not present.
• This is because the upgrade operation above has directly deleted the package or pip in my pip
  

Solution

使用 easy_install pip
这个命令，重新安装一下pip就好了
