Python's requests "Missing dependencies for SOCKS support" when using SOCKS5 from Terminal

Question

I'm trying to interact with an API from my Python 2.7 shell using a package that relies on Python's requests. Thing is the remote address is blocked by my network (university library).

So to speak to the API I do the following:

~$ ssh -D 8080 [email protected] 

And then, in new terminal, in local computer:

~$ export http_proxy=socks5://127.0.0.1:8080 https_proxy=socks5://127.0.0.1:8080 

Then I run the program in Python console but fails:

~$ python >>> import myscript >>> id = '1213' >>> token = 'jd87jd9' >>> connect(id,token)  File "/home/username/.virtualenvs/venv/local/lib/python2.7/site-packages/requests/sessions.py", line 518, in post     return self.request('POST', url, data=data, json=json, **kwargs)   File "/home/username/.virtualenvs/venv/local/lib/python2.7/site-packages/requests/sessions.py", line 475, in request     resp = self.send(prep, **send_kwargs)   File "/home/username/.virtualenvs/venv/local/lib/python2.7/site-packages/requests/sessions.py", line 585, in send     r = adapter.send(request, **kwargs)   File "/home/username/.virtualenvs/venv/local/lib/python2.7/site-packages/requests/adapters.py", line 370, in send     conn = self.get_connection(request.url, proxies)   File "/home/username/.virtualenvs/venv/local/lib/python2.7/site-packages/requests/adapters.py", line 273, in get_connection     proxy_manager = self.proxy_manager_for(proxy)   File "/home/username/.virtualenvs/venv/local/lib/python2.7/site-packages/requests/adapters.py", line 169, in proxy_manager_for     **proxy_kwargs   File "/home/username/.virtualenvs/venv/local/lib/python2.7/site-packages/requests/adapters.py", line 43, in SOCKSProxyManager     raise InvalidSchema("Missing dependencies for SOCKS support.") requests.exceptions.InvalidSchema: Missing dependencies for SOCKS support. 

This excerpt is from the adapters.py requests module:

> try: >     from .packages.urllib3.contrib.socks import SOCKSProxyManager except ImportError: >     def SOCKSProxyManager(*args, **kwargs): >         raise InvalidSchema("Missing dependencies for SOCKS support.") 

Now problem seems to be originated in urllib3's SOCKSProxyManager.

So I read you can use SOCKSProxyManager with SOCKS5 if you have install PySocks or you do a pip install urllib3[socks]

Alas, I tried both PySocks and urllib3 with Socks without any success.

Any idea of another workaround?

EDIT:

I also tried pip install requests[socks] (that's requests 2.10.0 with Socks support) and I am getting this:

  File "/home/username/.virtualenvs/venv/local/lib/python2.7/site-packages/requests/adapters.py", line 467, in send     raise ConnectionError(e, request=request) requests.exceptions.ConnectionError: SOCKSHTTPSConnectionPool(host='api-server.com', port=443): Max retries exceeded with url: /auth (Caused by NewConnectionError('<requests.packages.urllib3.contrib.socks.SOCKSHTTPSConnection object at 0x95c7ccc>: Failed to establish a new connection: SOCKS5 proxy server sent invalid data',)) 

Answer 1

This means that requests is using socks as a proxy and that socks is not installed.

Just run pip install pysocks
