无法在代理后面安装ruby gem

Question

我已经配置了http_proxy变量，并且能够使用curl和apt-get等。但是，当尝试运行“ gem install bundler”之类的命令时，出现代理错误。 为了让Ruby像其他工具一样尊重代理，我需要做些其他事情吗？

Answer 1

只是更精确一些。
407 Proxy Authentication Required错误意味着您必须为代理使用登录名和密码 。

您可以使用--http-proxy选项将其添加，格式如下：

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

但是， 如果您的密码包含某些特殊字符 ，则此方法将无效 。
实际上，由于选项值必须与URL匹配 ，因此禁止使用某些字符。

如果不确定，可以在执行命令之前在shell中执行以下操作，而不用在gem install命令中指定代理：

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

尝试这个：

sudo HTTP_PROXY =“ http://10.3.100.207:8080” gem install bundler

将“ 10.3.100.207”替换为代理，将“ 8080”替换为端口值”

它为我工作。

Answer 3

尝试将http-proxy设置添加到您的〜/ .gemrc文件中。

示例gemrc

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

Answer 4

我可以通过下载和配置ntlmaps来解决此问题。 很棒。 由于某种原因，gemrc文件代理没有帮助。

Answer 5

您必须在家庭用户文件夹的.bashrc文件中导出代理环境变量：

将这些行添加到.bashrc的末尾

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

记住要打开一个新的外壳程序窗口，以便外壳程序可以重新加载.bashrc文件。

如果使用sudo，则可以选择以root用户身份使用用户的环境变量，请编辑/etc/sudores文件并添加以下行：

Defaults env_keep += "http_proxy https_proxy"

如果您需要Microsoft代理上的代理身份验证，我建议使用cntlm代理： http ://cntlm.sourceforge.net/

默认情况下，cntlm使用3128端口，因此您必须更改.bashrc的环境变量：

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

要配置cntlm，这很容易解释，这里是重要的选项：

#
# 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# do not quote.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

对我来说@thomas提到的是有效的...

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

采用：

gem install --http-proxy http：// proxy-User ： Pass @ Proxy-Name ： 代理端口 gem-XYZ

您的通行证必须简单，没有特殊字符，否则会返回错误。
