我不能再使用conda实用程序了。我经常使用它多年，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）没有任何明显的异常，我得到错误下面的任何命令，一旦我使用conda （conda install ...，conda update ...，conda uninstall ...，...，消息总是一样的）：

我试着查看我的.condarc文件，甚至删除它但它不会改变pb。你知道我能做些什么才能回到工作的康茄舞吗？
好的。我遇到了与Anaconda 3 2018 ver相同的问题。所以我做的是我使用了Anaconda提示。它会自动将基本conda文件链接到所需的代理。只需在提示符中键入“conda --version”即可检查提示。然后输入“conda install numpy”。瞧！你完成了
降级到conda 4.5.5为我解决了这个问题。
戴着咆哮的帽子：这是大约18个月的第三次conda更新导致错误导致构建失败，并且还有很多其他问题。我认为它会在某些时候由核心conda人员修复，也许它是由第三方依赖项的特定组合引起的，但是这种或那种conda似乎总是非常错误。有一次更新导致conda install conda删除自己！
谢谢，有效！如果链接变旧，这里是简化的副本：
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)
删除到C:\Users\maglk\.condarc然后更新Conda。这将在Windows中解决它。
conda update conda
这个问题仍然存在于现场 - 在最新稳定的Anaconda（2018.12）的全新Windows 10安装中开始发生。在“conda install -c conda-forge xgboost”命令中获取“解决环境：失败”。我可以从基本频道安装一些东西，例如。 'conda install numpy'

我遇到了同样的问题并解决了。在Anaconda提示符中，使用pip install scp，而不是conda install scp
