SOCKS is an Internet protocol that exchanges network packets between a client and server. Bill wishes to download a web page from Jane, who runs a web server. The HTTP proxy connects to Jane's server, and then transmits back to Bill any. WinGate is a multi-protocol proxy server and SOCKS server for Microsoft.
I'm using pip 1.5.5 on python 2.7.6, CentOS 6.5 x8664. Python is compiled and installed in /usr/local/. While trying to install packages from requirements file, the first 12 packages are being downloaded via proxy, but after that pip tries to directly connect to the server instead of proxy and request fails. $ export httpsproxy= $ /usr/local/bin/pip2.7 install -r reqs.txt This results in download of first 12 packages via proxy, but the next one is a direct HTTPS request to the pypi server.
I've validated this via packet trace and proxy logs. Note that, the installation works flawlessly using /usr/bin/pip, v1.3.1. Here are the contents of reqs.pip requests1.2.3 Flask0.10.1 Flask-Login0.2.7 Flask-Security1.6.9 Flask-SQLAlchemy1.0 Flask-Script0.6.7 Flask-Principal0.4.0 Flask-WTF0.9.1 boto2.3.0 suds0.4 xmltodict0.8.6 simplejson3.3.3 stripe1.12.2 raven4.1.1 Flask-Migrate1.2.0 alembic0.6.3 Installation fails at stripe.
If I comment simplejson, it fails at raven. Here is the failure log. Note that, timeout is due to firewall dropping packets directly being sent to pypi server. Downloading/unpacking stripe1.12.2 (from -r /var/www/html/backend/reqs.pip (line 21)) Cleaning up.
I run pip install -r requirements.txt -proxy= my requirements.txt contains 20 entries, it installs the first 16 without any problems and then throws the error: Timeout: (, 'Connection to pypi.python.org timed out. (connect timeout=15)') Interestingly enough it always fails when installing the 16. Package ( django-session-csrf0.5)package but if I install the package manually using pip (not via the requirements.txt file) it works fine. If I run pip install -r requirements.txt -proxy= again after that it obviously skips django-session-csrf but then installs the following package without problems and then fails with the Timeout error on the package after that. Increasing the timeout to something like 300 doesn't help. Just like above, the script failed on 52nd requests for both pypi and imgur. Google worked fine.
Fails on 52 attempt. As above works fine with.
Running Ubuntu 12.04 running in host-only mode on VirtualBox, proxying through wingate on Windows 8.1 host. Hi, I've encountered the same problem in my Vagrant environment, running CentOS 6.5 and pip 1.5.6 with our corporate proxy. This seems to happen randomly on big requirements.txt that I try to install with pip when using the https proxy.
After investigation, I found that the problem seems to lie in the PoolManager of urllib3 that is embedded in the pip installation (vendor/requests/packages/urllib3/poolmanager.py:ProxyManager) I found a quick fix in the code that make my installation passes correctly. To confirm what I'm saying, just change this single line in the following file of your pip installation: $ diff /opt/venvs/ironic/lib/python2.6/site-packages/pip/vendor/requests/adapters.patch.py /opt/venvs/ironic/lib/python2.6/site-packages/pip/vendor/requests/adapters.py 209c209 if not proxy in self.proxymanager: The pip install works correctly afterward when instantiating a new ProxyManager object every time. Here is an example of error that I used to have for my pip install: $ pip install -r requirements.txt. Downloading/unpacking pecan=0.4.5 (from -r requirements.txt (line 25)) Cleaning up.
I also get this problem from within our company Windows network with different versions of pip.

I've found the line, it's now 178. Hi all can somebody help me?
I've tried to install mkdocs and got this error: C: Users Lenovo Localpip install mkdocs Collecting mkdocs Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'ConnectTimeoutError(, 'Connection to pypi.python.org timed out. (connect timeout=15)')': /simple/mkdocs/. This solution doesn't work anymore because line 209 is empty - any other idea??
(commented on Jul 2, 2014)I just add a True to the condition on line 209 of the adapter.py to always create a ProxyManager instance, thus skipping the pool manager logic. Python 3.5.3 pip 9.0.1 Thanks.
