I got this same error and it appears to have been caused by being behind a proxy server. In windows control panel, I set the following environment variables (for ALL users, rather than just my user):
HTTP_PROXY=https:///myproxyserver.somewhere.com/:80 HTTPS_PROXY=https:///myproxyserver.somewhere.com/:80 (obviously change the server and potentially the port number to your own configuration) Once they were set, I closed and reopened the command prompt and the pip install pyinstaller worked fine. -- Sent from: http://pyinstaller.47505.x6.nabble.com/ -- You received this message because you are subscribed to the Google Groups "PyInstaller" group.
