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??

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 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'：'（？）。

当我在没有 usrname 和密码的情况下运行命令时，它可以正常工作，但代理拒绝请求说它需要身份验证（“需要 407 身份验证”）。

我看了一眼，urllib3\poolmanager.py它似乎与用户名/密码没有任何关系。

这是在抱怨 URL 的方案（urlparse理解为 be myusr），以解决您应该这样做的问题：

get-pip.py --proxy http://myusr:mypswd@111.222.333.444:80

这是因为脚本需要环境变量 http_proxy 或 https_proxy 包含 URL 中的方案。设置环境变量

 export http_proxy="http://<hostname>:<port>"
 export https_proxy="https://<hostname>:<port>"

在运行“python get-pip.py”之前

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)

在您的 ips 中附加“http://”和“https://”。
我在使用 linux 时遇到了这个问题，windows 单独使用 ip 可以正常工作。

利用pip install xxx --proxy=https://xx.xx.xx.xx:xxxx

Python 3.6以后，在使用proxy时，proxy的参数值发生了requests.get(url=url, headers=headers, proxies=...)变化。

3.6之前包含，proxies={ 'https': '127.0.0.1:8080'}还是proxies={'http': '127.0.0.1:8080'}可以的，但是这种类型的字典不适合Python 3.7及以上。

Python3.7及以上，必须在ip:port前面加上http://or https://，即，proxies={'http':'http://127.0.0.1:8080'}或proxies={'https':'https://127.0.0.1:8080'}

对于您提到的问题，这取决于如何设置代理服务器身份验证。例如，我的 Intranet 使用 Windows AD，并且代理服务器可能正在使用 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，可能是由于集成的身份验证。

因此，您需要找出代理服务器正在使用的身份验证。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，以检查服务器支持的身份验证机制.

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。

以下事情对我有用：

步骤 1) 设置 HTTPS_PROXY 和 HTTP_PROXY：

导出 HTTPS_PROXY="http://proxy-address:8080"

导出 HTTP_PROXY="http://proxy-address:8080"

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"

在 Windows 上，您可以使用SET命令而不是export：

  • SET HTTP_PROXY="http://proxy-address:8080"
  • SET HTTPS_PROXY="http://proxy-address:8080"

如果您不在代理后面，则需要像这样取消设置：

  • SET HTTP_PROXY=
  • SET HTTPS_PROXY=

它可以在win7上安装boto3。pip install boto3 --proxy=https://user:pwd@xxxx:8080
