truffle migrate / truffle obtain behind (corporate) proxy

[imbenwolf]

Issue

Truffle cannot fetch solc from solc-bin behind a proxy even when setting HTTP_PROXY and HTTPS_PROXY env variables.

I propose to:

• add proxy option inside truffle-config OR
• add --proxy as option when running truffle in general OR
• add --proxy as option when running truffle command (migrate/compile/obtain) OR
• acknowledge HTTP_PROXY and HTTPS_PROXY env variables

Steps to Reproduce

1. Connect to a network behind proxy
2. Change solc version inside truffle-config.js to a non-default version (e.g 0.4.24 on truffle v5)
   3.1 Execute truffle migrate/compile --> error
   3.2 Execute truffle obtain --solc= (e.g 0.4.24) --> no error but does not download

Expected Behavior

solc is downloaded and migrations are executed with correct version

Actual Results

command fails

Environment

• Operating System: Windows 10
• Ethereum client: ganache-cli
• Truffle version (truffle version): 5.0.6
• node version (node --version): 10.15.2
• npm version (npm --version): 6.4.1

Definitely we should support that! Will look into fixing this. Thanks for raising the issue!

Any update on this?

[h3nk42]

Is there any way to use Truffle behind a corporate proxy right now?

@gnidan Any thoughts as to whether this might be something we can do anything about or if there is perhaps a workaround related to the network configuration?

[gnidan]

How does this work for Node.js in other projects? Shouldn't Node just respect the network configuration? Any insight here would be helpful!

I met the same problem, and I started an http proxy ( using pproxy + socks5 ) , and make this bash file:

# my_env
export HTTP_PROXY="http://192.168.10.54:8080"
export HTTPS_PROXY="http://192.168.10.54:8080"
export http_proxy="http://192.168.10.54:8080"
export https_proxy="http://192.168.10.54:8080"

source my_env and then run truffle command, everything is OK.
