pip, proxy authentication and "Not supported proxy scheme"
提问by Kashyap
Trying to install pip on a new python installation. I am stuck with proxy errors. Looks like a bug in get-pipor urllib3??
尝试在新的 python 安装上安装 pip。我被代理错误困住了。看起来像一个错误get-pip或urllib3??
Question is do I have to go through the pain of setting up CNTLM as described hereor is there a shortcut?
问题是我是否必须像这里描述的那样经历设置CNTLM的痛苦，还是有捷径？
get-pip.py documentationsays use --proxy="[user:passwd@]proxy.server:port"option to specify proxy and relevant authentication. But seems like pip passes on the whole thing as it is to urllib3which interprets "myusr" as the url scheme, because of the ':' I guess (?).
get-pip.py 文档说使用--proxy="[user:passwd@]proxy.server:port"选项来指定代理和相关身份验证。但似乎 pip 传递了整个事情，因为它将urllib3“myusr”解释为 url 方案，因为我猜是（？）。

When I run the command without the usrname and password it works fine, but proxy rejects the request saying it needs authentication ("407 authenticationrequired").
当我在没有 usrname 和密码的情况下运行命令时，它工作正常，但代理拒绝了请求，说它需要身份验证（“407 authenticationrequired”）。

I had a brief look at urllib3\poolmanager.pyand it doesn't seem to have anything to do with username/passwords.
我看了一眼，urllib3\poolmanager.py它似乎与用户名/密码没有任何关系。

This is complaining about the scheme for the URL (which urlparseis understanding to be myusr), to work around that you should instead be doing:
这是在抱怨 URL 的方案（urlparse理解为myusr），以解决您应该做的事情：
get-pip.py --proxy http://myusr:[email protected]:80
回答by Junger
This is because the script requires the environment variables http_proxy or https_proxy contains the scheme in the URL. Set the environment variables
这是因为脚本需要环境变量 http_proxy 或 https_proxy 在 URL 中包含方案。设置环境变量
export http_proxy="http://<hostname>:<port>"
export https_proxy="https://<hostname>:<port>"
before run the "python get-pip.py"
在运行“python get-pip.py”之前

For the problem you have mentioned, it depends on how the proxy server authentication has been set up.
For example, my intranet uses Windows AD and probably the proxy server is using Windows Integrated auth. Thus when I do pip install --proxy http://<server-ip>:<port> <module-name>, it works fine. Note that I did not have to type in username & password ,likely due to integrated auth.
对于您提到的问题，这取决于代理服务器身份验证是如何设置的。例如，我的 Intranet 使用 Windows AD，而代理服务器可能使用 Windows Integrated auth。因此，当我这样做时pip install --proxy http://<server-ip>:<port> <module-name>，它工作正常。请注意，我不必输入用户名和密码，可能是由于集成了身份验证。
So, you'll need to find out the authentication being used by your proxy server.You can use Fiddler(or any other network analyzer) tool to check the WWW-Authenticate headers in the 407 response, to check what auth mechs the server supports.
因此，您需要找出代理服务器使用的身份验证。您可以使用 Fiddler（或任何其他网络分析器）工具检查 407 响应中的 WWW-Authenticate 标头，以检查服务器支持哪些身份验证机制.

This can be a case when you use ";" in your passwords. This cannot be parsed properly that results in ProxySchemeUnknown error raised.
当您使用“;”时可能会出现这种情况 在您的密码中。这无法正确解析，导致引发 ProxySchemeUnknown 错误。

The below things worked for me :
以下事情对我有用：
Step 1) Set HTTPS_PROXY and HTTP_PROXY:
步骤 1) 设置 HTTPS_PROXY 和 HTTP_PROXY：
export HTTPS_PROXY="http://proxy-address:8080"
导出 HTTPS_PROXY="http://proxy-address:8080"
export HTTP_PROXY="http://proxy-address:8080"
导出 HTTP_PROXY="http://proxy-address:8080"
step 2) : Run pip with below configuration
步骤 2) : 使用以下配置运行 pip
./pip.exe install pyspark --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org --proxy "proxy-address:8080"
./pip.exe 安装 pyspark --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org --proxy "proxy-address:8080"

import requests
proxy = {
'http' : 'http://138.197.222.35:80',
'https' : 'http://1138.197.222.35:8080'
}
r = requests.get('http://httpbin.org/ip', proxies=proxy)
print (r)
Append 'http://' and 'https://' with your ips.
I had this issue when working with linux, windows worked fine with ip alone.
使用您的 ip 附加“http://”和“https://”。
我在使用 linux 时遇到了这个问题，windows 单独使用 ip 工作正常。
