Proxy error

Question

I am trying to install multiple package packages per proxy. Ive installed env,

http_proxy=http://172.16.2.3:3128 https_proxy=http://172.16.2.3:3128 

Then I tried pip, but we get an error,

 [ root@server ~]# pip install --proxy=http://172.16.2.3:3128 virtualenv -v Starting new HTTPS connection (1): pypi.python.org There was an error checking the latest version of pip Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/pip/utils/outdated.py", line 122, in pip_version_check headers={"Accept": "application/json"}, File "/usr/lib/python2.7/site-packages/pip/_vendor/requests/sessions.py", line 477, in get return self.request('GET', url, **kwargs) File "/usr/lib/python2.7/site-packages/pip/download.py", line 373, in request return super(PipSession, self).request(method, url, *args, **kwargs) File "/usr/lib/python2.7/site-packages/pip/_vendor/requests/sessions.py", line 465, in request resp = self.send(prep, **send_kwargs) File "/usr/lib/python2.7/site-packages/pip/_vendor/requests/sessions.py", line 573, in send r = adapter.send(request, **kwargs) File "/usr/lib/python2.7/site-packages/pip/_vendor/cachecontrol/adapter.py", line 46, in send resp = super(CacheControlAdapter, self).send(request, **kw) File "/usr/lib/python2.7/site-packages/pip/_vendor/requests/adapters.py", line 424, in send raise ConnectionError(e, request=request) ConnectionError: HTTPSConnectionPool(host='pypi.python.org', port=443): Max retries exceeded with url: /pypi/pip/json (Caused by ProxyError('Cannot connect to proxy.', error('Tunnel connection failed: 403 Forbidden',))) Collecting virtualenv Getting page https://pypi.python.org/simple/virtualenv/ Starting new HTTPS connection (1): pypi.python.org Incremented Retry for (url='/simple/virtualenv/'): Retry(total=4, connect=None, read=None, redirect=None) Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'ProxyError('Cannot connect to proxy.', error('Tunnel connection failed: 403 Forbidden',))': /simple/virtualenv/ 

It seems curl is working (?)

 [ root@server ~]# curl -I https://pypi.python.org/simple/virtualenv/ HTTP/1.1 200 Connected HTTP/1.1 200 OK Server: nginx/1.8.0 Content-Type: text/html; charset=utf-8 X-PYPI-LAST-SERIAL: 1916396 Cache-Control: max-age=600, public X-Clacks-Overhead: GNU Terry Pratchett 

Any ideas?

Answer 1

You can specify a proxy as a parameter to install pip:

 pip install <package> --proxy http://your.proxy.net:8080/ 

If you also encounter ssl certificate errors (also common in corporate environments), you can also enable pypi as a trusted host:

 pip install <package> --proxy http://your.proxy.net:8080/ --trusted-host pypi.python.org 

Answer 2

This problem can be solved in the terminal.

 ./configure --enable-loadable-sqlite-extensions && make && make install
