conda 返回“解决环境:失败" [英] conda returns 'Solving environment: failed'

问题描述

我不能再使用 conda 实用程序了.多年来我经常使用它，但最近，因为我安装了 python 模块 scp(使用命令 conda install scp，我不知道它是否重要)，没有任何明显的东西不寻常，我一使用 conda(conda install ...，conda update ...，conda uninstall ...，...，消息始终相同)，就会收到以下错误:

I can not use the conda utility anymore. I use it regularly since years but lately, since I installed the python module scp (with the command conda install scp, I don’t know if it matters) without anything visibly unusual, I get the error below whatever the command as soon as I use conda (conda install …, conda update …, conda uninstall …, … , the message is always the same):

Solving environment: failed

An unexpected error has occurred. Conda has prepared the above report.
If submitted, this report will be used by core maintainers to improve
future releases of conda.
Would you like conda to send this report to the core maintainers?

我试图查看我的 .condarc 文件，甚至删除了它，但它并没有改变 pb.你知道我可以做些什么来回到一个正常工作的 conda 吗?

I tried to look at my .condarc file and even removed it but it doesn't change the pb. Do you know what I can do to go back to a working conda ?

推荐答案

谢谢你，成功了！如果链接变旧，这里是简化的副本:

thank you, that works ! in case the link grows old, here is the simplified copy:

1. 导航到您的 conda 基础环境，由 conda info 提供.
2. 打开文件 lib/pythonX.Y/site-packages/conda/gateways/connection/init.py.其中 X.Y 是 python 主要-次要版本.

3. 将函数should_bypass_proxies_patched"替换为:

1. Navigate to your conda base environment, as given by conda info.
2. Open the file lib/pythonX.Y/site-packages/conda/gateways/connection/init.py. Where X.Y is the python major-minor version.

3. Replace the function 'should_bypass_proxies_patched' with :

def should_bypass_proxies_patched(should_bypass_proxies_func, url, no_proxy=None):
    if url.startswith("file://"):
        return True
    try:
        return should_bypass_proxies_func(url, no_proxy)
    except TypeError:
        return should_bypass_proxies_func(url)
