Pip: PIP ProtocolError 'Connection aborted' on trying to connect to pypi.python.org even if no-link is specified

[debraj-manna]

Environment

• pip version: 7.1.2
• Python version: 2.7.6
• OS: Ubuntu 14.04

Description
On trying to do a install via PIP like below

sudo pip install -U --verbose --force-reinstall --allow-unverified --no-index --find-links=/tmp/chef-cache/patroni patroni[zookeeper]==1.4.4

I am seeing logs like below and it is taking more than an hour for the installation to complete even though I am trying to do the installation from local.

 The directory '/home/ubuntu/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Even though the installation is from local and --no-index is specified PIP is still trying to connect to pypi.python.org. I also tried by specifying --disable-pip-version-check (even though this is implied by --no-index option) but still PIP was trying to connect to pypi.python.org.

This can slow down the installation considerably if in a system without internet firewall is dropping the traffic instead of reject.

I think if --no-index is specified and --find-links is pointing to a local file system then PIP should not try to connect to pypi.python.org.

Anyone any update on this?

[benoit-pierre]

That's a really old version, can you reproduce with the latest release?

I have the same issue after upgrading pip

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\Arrowana\AppData\Local\Temp\pip-install-3e2qvzvx\Twisted\

Content of pkg folder:

Twisted-18.9.0.tar.bz2
incremental-16.10.1.tar.gz
... other Twisted dependencies

--no-index is behaving well for my other dependencies which are .whl

[pfmoore]

Twisted uses setup_requires to require "incremental". The setup_requires processing is done by setuptools, and doesn't respect pip's command line options. To fix this, you'd need to request that the twisted project stop using setup_requires.

I downloaded a custom Twisted wheel from https://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted

Same Twisted version but now it works and picks up the local incremental

Hi,
I also have the same issue,
I am using
Python 3.7
pip 19.1

when i try to install any package (Module) i get this error
can anyone give me a solution on this?

[AnmolTomer]

Same issue here also. I am running pip3 in WSL. sudo apt install works perfectly, but pip3 is not working. Following is my pip and python version

pip3 install -upgrade pip3 Also gives the same error.

Specs of the machine on which I am trying are these :

Any help would be appreciated. Thank You.

[Kotork]

Hey guys,

I had the same problem on cmd. I switch to windows power shell and it worked ok for new packages.
Still give me the same error for updates

[chrahunt]

@debraj-manna, please let us know if trying with the new version did not work for you.

Hey @mca27 and @AnmolTomer, those look like unrelated connectivity issues (this issue is specifically about using --no-index). If this is still happening to you, please create a new issue so we can help troubleshoot.

Hi @Kotork. If you are still facing issues, please feel free to create a separate issue so we can investigate your situation specifically.

[debraj-manna]

@chrahunt - I am not seeing this with the version 18.1.

[chrahunt]

Thanks @debraj-manna. I'll proceed to close this. Let us know if you have any other issues.
