问题:

I am freaking out with this error I am struck on for 2 days. 2 days ago activated my virtualenv, then tried to install some dependencies but pip install keeps throwing this error.

pip install django Traceback (most recent call last):   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/basecommand.py", line 215, in main     status = self.run(options, args)   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/commands/install.py", line 335, in run     wb.build(autobuilding=True)   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/wheel.py", line 749, in build     self.requirement_set.prepare_files(self.finder)   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/req/req_set.py", line 380, in prepare_files     ignore_dependencies=self.ignore_dependencies))   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/req/req_set.py", line 554, in _prepare_file     require_hashes   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/req/req_install.py", line 278, in populate_link     self.link = finder.find_requirement(self, upgrade)   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/index.py", line 465, in find_requirement     all_candidates = self.find_all_candidates(req.name)   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/index.py", line 423, in find_all_candidates     for page in self._get_pages(url_locations, project_name):   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/index.py", line 568, in _get_pages     page = self._get_page(location)   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/index.py", line 683, in _get_page     return HTMLPage.get_page(link, session=self.session)   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/index.py", line 792, in get_page     "Cache-Control": "max-age=600",   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/_vendor/requests/sessions.py", line 488, in get     return self.request('GET', url, **kwargs)   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/download.py", line 386, in request     return super(PipSession, self).request(method, url, *args, **kwargs)   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/_vendor/requests/sessions.py", line 475, in request     resp = self.send(prep, **send_kwargs)   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/_vendor/requests/sessions.py", line 596, in send     r = adapter.send(request, **kwargs)   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/_vendor/cachecontrol/adapter.py", line 47, in send     resp = super(CacheControlAdapter, self).send(request, **kw)   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/_vendor/requests/adapters.py", line 390, in send     conn = self.get_connection(request.url, proxies)   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/_vendor/requests/adapters.py", line 290, in get_connection     proxy_manager = self.proxy_manager_for(proxy)   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/_vendor/requests/adapters.py", line 184, in proxy_manager_for     **proxy_kwargs   File "/home/blackpython/.local/lib/python2.7/site-packages/pip/_vendor/requests/adapters.py", line 43, in SOCKSProxyManager     raise InvalidSchema("Missing dependencies for SOCKS support.") InvalidSchema: Missing dependencies for SOCKS support. 

I tried installing request[socks], but then I get an error saying that it cannot make out the socks version

printenv | grep -i proxy NO_PROXY=localhost,127.0.0.0/8,::1 http_proxy=http://proxy.iiit.ac.in:8080/ FTP_PROXY=http://proxy.iiit.ac.in:8080/ ftp_proxy=http://proxy.iiit.ac.in:8080/ all_proxy=socks://proxy.iiit.ac.in:8080/ ALL_PROXY=socks://proxy.iiit.ac.in:8080/ https_proxy=http://proxy.iiit.ac.in:8080/ HTTPS_PROXY=http://proxy.iiit.ac.in:8080/ no_proxy=localhost,127.0.0.0/8,::1 HTTP_PROXY=http://proxy.iiit.ac.in:8080/ 

This is proxy setting on my system, can anyone help me with this? Thanks edit: I tired reinstalling ubuntu, and I am still facing this error

回答1:

  1. Unset socks proxy, in your case: unset all_proxy unset ALL_PROXY
  2. Install missing dependencies: pip install pysocks
  3. Reset proxy, source .bashrc, and pip install works again with socks proxy.


回答2:

I was also not able to install Django and other stuffs after activating venv than I finally did this [1]

type: sudo gedit .bashrc #or any text editor if gedit is not there         add this line at the last of your .bashrc file        export all_proxy="https://your_proxy:your_port/" 

save the changes it should work. Thanks

回答3:

This is what worked for me pip install --user --proxy https://user:pass@proxyaddress:port django



回答4:

Uninstall the installed package using

pip uninstall packagename 

and set the proxy

http_proxy=http://username:password@host:port/ https_proxy=https://username:password@host:port/  

and try to install using

pip install packagename
