'ProtocolError('Connection aborted.', InvalidURL("URL can't contain control characters. ' ' (found at least ' ')"))': /simple/pandas

While trying to install any package using pip I am getting error:

for example pip install pandas --proxy proxy_value

WARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProtocolError('Connection aborted.', InvalidURL("URL can't contain control characters. ' ' (found at least ' ')"))': /simple/pandas

I have uninstalled python and freshly installed python 3.9.13 and set the system variables to C:\Users\richa1\AppData\Local\Programs\Python\Python39\Scripts\

I have checked with 3.10.5 too.

But still not able to fix it. I am not sure if this is some issue with installed file or something I need to set.

Solution

  • As discussed in the comments, the error stems from a malformed HTTP proxy setting.

    In this case, the http_proxy variable had been set to '' instead of the empty string, and a quote character is indeed a control character not allowed in an URL.
