pip connection issue in virtual enviroment

[ghost]

• pip version: 10.0.1
• Python version: 3.7
• OS: windows 10

I'm in an enterprise setup, but I'm not behind a proxy.
I'm using git bash.

Description
I can't install modules with pip when I'm inside a virtual enviroment. I can install modules with pip, when I'm not inside a virtual enviroment.

The error I'm getting is: "Failed to establish a new connection: [Errno 11003] getaddrinfo failed')': /simple/modulename"

Example of installing/updating pip with trusted hosts enabled outside the virtual enviroment

$ python -m pip install --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org --upgrade pip
Requirement already up-to-date: pip in c:\users\penyme\appdata\local\programs\python\python37\lib\site-packages (10.0.1)

Example of the same operation within a virtual enviroment:

$ source env/Scripts/activate
x@x MINGW64 /p/Workspace/_poc/DjangoTango/DjangoTango
(env)
$ python -m pip install --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org --upgrade pip

Pip is up-to-date, but when I try to install Djnago it looks like this:

Something seems indeed to be broken inside your virtual environment.
Does python -c "import socket;print(socket.getaddrinfo('pypi.org', 443))" work inside it ?

[pradyunsg]

@xavfernandez beat me to it. :)

As an aside, putting pip's output in a code block (by surrounding it with ``` above and below) would make it easier to read. :)

@xavfernandez
Doesn't seem like it. This is from the virtual enviroment:

$ python -c "import socket;print(socket.getaddrinfo('pypi.org', 443))"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "C:\Users\x\AppData\Local\Programs\Python\Python37\lib\socket.py", line 748, in getaddrinfo
    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno 11003] getaddrinfo failed

This is from outside:

$ python -c "import socket;print(socket.getaddrinfo('pypi.org', 443))"
[(<AddressFamily.AF_INET: 2>, 0, 0, '', ('151.101.128.223', 443)), (<AddressFamily.AF_INET: 2>, 0, 0, '', ('151.101.0.223', 443)), (<AddressFamily.AF_INET: 2>, 0, 0, '', ('151.101.192.223', 443)), (<AddressFamily.AF_INET: 2>, 0, 0, '', ('151.101.64.223', 443))]

It's not just tied to this virtualenviroment, but is the same for all of them.

[xavfernandez]

@Sidstling you apparently have an issue with the python used inside your venvs.
Is it the same as the global one ?

[ghost]

@xavfernandez
I'm not sure how to check exactly, but it seems like the fact that I'm operating on a network drive while having python installed on my c drive is what is breaking the venv, because when I just tried to make a venv on a temp folder on my cdrive I got:

$ source envtest/Scripts/activate
(envtest)
x@x MINGW64 /c/work
$ python -c "import socket;print(socket.getaddrinfo('pypi.org', 443))"
[(<AddressFamily.AF_INET: 2>, 0, 0, '', ('151.101.192.223', 443)), (<AddressFamily.AF_INET: 2>, 0, 0, '', ('151.101.128.223', 443)), (<AddressFamily.AF_INET: 2>, 0, 0, '', ('151.101.0.223', 443)), (<AddressFamily.AF_INET: 2>, 0, 0, '', ('151.101.64.223', 443))]

Modules also download and install.

[pradyunsg]

@Sidstling is your issue fixed? If so, it'd be helpful for someone else who might be facing this issue if you could mention how you resolved it. :)

[ghost]

@pradyunsg it’s not fixed exactly, but the issue is with how venvs are created on network drives and not what I originally described.

I avoid the issue by not using the network drive to create my venvs.

[hedrickbt]

I received the same error when I ran from a network drive (H:) vs a local (C:) drive. Python 3.6
