为什么我不能安装 python 包？

Question

Context :

I am installing the packages from a cloned repo with pip.

What I was doing when I ran into problems:

python3 -m pip install --proxy "http://internal.url:8080" --upgrade pip //Update pip and set proxy server

pip install -r requirements.txt // install packages

Result :

WARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x000001F6DF6CB7C0>: Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it')': /simple/azure-mgmt-resource/ ERROR: Could not find a version that satisfies the requirement azure-mgmt-resource (from -r requirements.txt (line 1)) (from versions: none) ERROR: No matching distribution found for azure-mgmt-resource (from -r requirements.txt (line 1))

My System : - Windows 10 - Python 3.8.3rc1 - Pip 20.1

I've updated pip : Some SO answers say that the issue is a need to update pip. I've tried this answer , which called for: curl https://bootstrap.pypa.io/get-pip.py | python curl https://bootstrap.pypa.io/get-pip.py | python

The result was:

C:\PythonApps\carrieralloc-poc>curl https://bootstrap.pypa.io/get-pip.py | python

"connection refused" is a theme here.

This blog suggested that perhaps my ip address was blacklisted (doubtful as I'm using a corporate proxy) But I tried his suggestion and ran curl https://pypi.org

The results: curl: (7) Failed to connect to pypi.org port 443: Connection refused

I got to wondering if my proxy is set correctly :

I can't find a command for checking my proxy.

Any pointers? Thank you!

Answer 1

You're on windows, right?

I imagine you would get the same if you tried to use powershell to do the same thing.

Try this:

Invoke-WebRequest -URI https://www.google.ca

If the command above is successful, you should expect a HTTP response, otherwise it should error out like the rest of your stuff.

Try running this powershell command to retrieve your proxy address:

[System.Net.Webproxy]::GetDefaultProxy()

Answer 2

The solution was to turn off my corporate VPN. Doh!
