无法在代理后面安装ruby gem

Question

I have configured my http_proxy variable, and am able to use curl, and apt-get, etc. However, when trying to run a command such as "gem install bundler" I get a proxy error. Is there something different I need to do in order to get Ruby to respect the proxy like every other tool is doing?

Answer 1

Just some more precision.
Your 407 Proxy Authentication Required error means you have to use a login and password for your proxy .

You can use the --http-proxy option to add it, with the following pattern:

gem install --http-proxy http://login:password@proxyServer:proxyPort yourGem

BUT, this will not work if your password contains some special character .
Effectively, as the option value must match an URL , some characters are forbidden.

If you are unsure, instead of specifying the proxy in the gem install command, you can do in the shell, before executing the command, with:

set HTTP_PROXY=http://proxyServer:proxyPort
set HTTP_PROXY_USER=login
set HTTP_PROXY_PASS=password
set HTTPS_PROXY=http://proxyServer:proxyPort
set HTTPS_PROXY_USER=login
set HTTPS_PROXY_PASS=password

Answer 2

Try this:

sudo HTTP_PROXY="http://10.3.100.207:8080" gem install bundler

Replace "10.3.100.207" with your proxy and "8080" with your port value"

It worked for me.

Answer 3

Try adding the http-proxy setting to your ~/.gemrc file.

Example gemrc

--- 
gem: --no-ri --no-rdoc
http-proxy: http://example.com:80

Answer 4

I was able to solve this by downloading and configuring ntlmaps. Worked great. For some reason the gemrc file proxy did not help.

Answer 5

You have to export the proxy environment variables in the .bashrc file of your home user folder:

Add these lines at the end of your .bashrc

export http_proxy="http://proxy:80"
export https_proxy="http://proxy:80"

Remembert to open a new shell window, so the shell can reload the .bashrc file.

If you are using sudo there's an option to use the environment vars of the user as root, edit your /etc/sudores file and add this line:

Defaults env_keep += "http_proxy https_proxy"

If you need proxy authentication on a microsoft proxy, i recommend the cntlm proxy: http://cntlm.sourceforge.net/

By default cntlm uses the 3128 port, so you have to change the environment variables of .bashrc :

export http_proxy="http://localhost:3128"
export https_proxy="http://localhost:3128"

To configure cntlm it is pretty self explanatory, here you are the important options:

#
# Cntlm Authentication Proxy Configuration
#
# NOTE: all values are parsed literally, do NOT escape spaces,
# do not quote. Use 0600 perms if you use plaintext password.
#

Username        testuser
Domain          corp-uk
Password        password
# NOTE: Use plaintext password only at your own risk
# Use hashes instead. You can use a "cntlm -M" and "cntlm -H"
# command sequence to get the right config for your environment.
# See cntlm man page
# Example secure config shown below.
# PassLM          1AD35398BE6565DDB5C4EF70C0593492
# PassNT          77B9081511704EE852F94227CF48A793
### Only for user 'testuser', domain 'corp-uk'
# PassNTLMv2      D5826E9C665C37C80B53397D5C07BBCB

# Specify the netbios hostname cntlm will send to the parent
# proxies. Normally the value is auto-guessed.
#
# Workstation   netbios_hostname

# List of parent proxies to use. More proxies can be defined
# one per line in format <proxy_ip>:<proxy_port>
#
Proxy           10.0.0.41:8080
Proxy           10.0.0.42:8080
[...]

Answer 6

For me what @thomas mentioned worked ...

set HTTP_PROXY=http://proxyServer:proxyPort
set HTTP_PROXY_USER=login
set HTTP_PROXY_PASS=password
set HTTPS_PROXY=http://proxyServer:proxyPort
set HTTPS_PROXY_USER=login
set HTTPS_PROXY_PASS=password

Answer 7

use:

gem install --http-proxy http:// proxy-User : Pass @ Proxy-Name : Proxy-Port gem-XYZ

Your pass need be simple, without special characters or will return an error.
