pip install 不起作用，InvalidSchema：缺少 SOCKS 支持的依赖项

问题描述 投票：0回答：5

我被这个错误吓坏了，我已经被这个错误困扰了两天了。 2 天前激活了我的 virtualenv，然后尝试安装一些依赖项，但 pip install 不断抛出此错误。

pip install django

我尝试安装 request[socks]，但随后收到一条错误消息，指出它无法识别袜子版本 

printenv | grep -i proxy
NO_PROXY=localhost,127.0.0.0/8,::1
http_proxy=http://proxy.iiit.ac.in:8080/
FTP_PROXY=http://proxy.iiit.ac.in:8080/
ftp_proxy=http://proxy.iiit.ac.in:8080/
all_proxy=socks://proxy.iiit.ac.in:8080/
ALL_PROXY=socks://proxy.iiit.ac.in:8080/
https_proxy=http://proxy.iiit.ac.in:8080/
HTTPS_PROXY=http://proxy.iiit.ac.in:8080/
no_proxy=localhost,127.0.0.0/8,::1
HTTP_PROXY=http://proxy.iiit.ac.in:8080/

这是我系统上的代理设置，有人可以帮助我吗？ 谢谢 编辑：我厌倦了重新安装 ubuntu，但我仍然面临这个错误

python pip socks

  1. 根据您的情况取消设置袜子代理： 
    
unset all_proxy
unset ALL_PROXY
  2. 安装缺少的依赖项： 
    
pip install pysocks
  3. 重置代理，
    source .bashrc
    和
    pip install
    再次与socks代理一起使用。

激活 venv 后我也无法安装 Django 和其他东西，但我最终做到了 [1]

type: sudo gedit .bashrc #or any text editor if gedit is not there 

      add this line at the last of your .bashrc file 
      export all_proxy="https://your_proxy:your_port/"

保存它应该起作用的更改。谢谢

这对我有用

pip  install --user --proxy https://user:pass@proxyaddress:port django

使用

卸载已安装的软件包 
pip uninstall packagename

并设置代理

http_proxy=http://username:password@host:port/
https_proxy=https://username:password@host:port/

并尝试使用

安装 
pip install packagename

如果必须通过 SOCKS 代理访问互联网，则

pip install pysocks
的标准命令将不起作用，因为没有所需的 SOCKS 支持来安装提供它的包，从而有效地创建了一个鸡和鸡蛋问题。

要解决此问题，请导航到 https://pypi.org/project/PySocks/#files，下载与所使用的 Python 版本相关的轮子，然后使用 

pip install -U /path/to/wheel
手动安装它，例如 

$ pip install -U pip
ERROR: Could not install packages due to an OSError: Missing dependencies for SOCKS support.
$ pip install pysocks
ERROR: Could not install packages due to an OSError: Missing dependencies for SOCKS support.
$ wget https://files.pythonhosted.org/.../PySocks-1.7.1-py3-none-any.whl
...
2024-04-06 00:00:00 (84.5 MB/s) - ‘PySocks-1.7.1-py3-none-any.whl’ saved [16725/16725]
$ pip install -U PySocks-1.7.1-py3-none-any.whl 
...
Successfully installed PySocks-1.7.1
$ pip install -U pip
...
Successfully installed pip-24.0

在上面的示例中，我使用了 

wget
，它可能在您的平台上不可用，因此您可能需要使用替代命令，或者只需使用网络浏览器（最常见于 Windows）来下载文件，然后使用在下载文件的路径上使用相同的 
pip install -U
命令。
