Trying to install pip on a new python installation. I am stuck with proxy errors. Looks like a bug in get-pip
or urllib3
??
Question is do I have to go through the pain of setting up CNTLM as described here or is there a shortcut?
get-pip.py documentation says use --proxy="[user:passwd@]proxy.server:port"
option to specify proxy and relevant authentication. But seems like pip passes on the whole thing as it is to urllib3
which interprets "myusr" as the url scheme, because of the ':' I guess (?).
C:\ProgFiles\Python27>get-pip.py --proxy myusr:mypswd@111.222.333.444:80

When I run the command without the usrname and password it works fine, but proxy rejects the request saying it needs authentication ("407 authenticationrequired").

I had a brief look at urllib3\poolmanager.py
and it doesn't seem to have anything to do with username/passwords.
For the problem you have mentioned, it depends on how the proxy server authentication has been set up. For example, my intranet uses Windows AD and probably the proxy server is using Windows Integrated auth. Thus when I do
pip install --proxy http://<server-ip>:<port> <module-name>
, it works fine. Note that I did not have to type in username & password ,likely due to integrated auth.So, you'll need to find out the authentication being used by your proxy server.You can use Fiddler(or any other network analyzer) tool to check the WWW-Authenticate headers in the 407 response, to check what auth mechs the server supports.
The below things worked for me :
Step 1) Set HTTPS_PROXY and HTTP_PROXY:
export HTTPS_PROXY="http://proxy-address:8080"
export HTTP_PROXY="http://proxy-address:8080"
step 2) : Run pip with below configuration
./pip.exe install pyspark --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org --proxy "proxy-address:8080"
This is complaining about the scheme for the URL (which
urlparse
is understanding to bemyusr
), to work around that you should instead be doing:This is because the script requires the environment variables http_proxy or https_proxy contains the scheme in the URL. Set the environment variables
before run the "python get-pip.py"
This can be a case when you use ";" in your passwords. This cannot be parsed properly that results in ProxySchemeUnknown error raised.
