http: error: InvalidSchema: Missing dependencies for SOCKS support. despite installing requests[socks]

[cl-ax]

I followed the documentation's instructions to install requests[socks] with pip -U requests[socks], but I'm still getting the error.

$ http --version
0.9.8

Using Ubuntu 18.04 with the following env vars set:

$ env | grep -i proxy
HTTP_PROXY=socks5h://localhost:8118
FTP_PROXY=socks5h://localhost:8118
http_proxy=socks5h://localhost:8118
ALL_PROXY=socks5h://localhost:8118
NO_PROXY=localhost,127.0.0.0/8,::1,company.com
HTTPS_PROXY=socks5h://localhost:8118
RSYNC_PROXY=socks5h://localhost:8118

httpie installed with sudo apt install httpie

It’s possible that the apt-installed version of HTTPie does not have access to the additional pip-installed packages, for some reason. Also, HTTPie 0.9.8 is very old (it might be unrelated, though). I would try to install HTTPie using pip instead.

[cl-ax]

I must be doing something wrong... I tried installing with pip after removing using apt, but I'm now getting errors when trying to run httpie:

$ pip install -U httpie

@coaxial-abraxas can you please tell me what Python version you use?

$ python --version

I assume it will be older than the 3.6, which is required by HTTPie 2.0.0+. The following should work:

$ pip install 'httpie<2.0.0'

(This is indeed a bug: #886)

[cl-ax]

For the time being, I have installed it with python3 -m pip install -U httpie. My Python3 is 3.6.9, and python is 2.7.17. Now using httpie 2.1.0 without issue.

$ python --version
Python 2.7.17

$ python3 --version
Python 3.6.9

$ http --version
2.1.0

HTTPie 2.3.0 will support SOCKS out of the box w/o extra installation.
