Question

我不能再使用conda实用程序。我多年来一直定期使用它，但是最近，由于我安装了python模块scp（使用命令conda install scp，我不知道它是否重要）而没有任何明显的异常，因此我得到的错误低于我使用conda时立即执行命令（conda安装…，conda更新…，conda卸载…，…，消息始终是相同的）：

Solving environment: failed

我试图查看我的.condarc文件，甚至删除了它，但它并没有改变pb。您知道我能做些什么才能恢复正常工作吗？

Answer 1

好的。我在Anaconda 3 2018 ver中遇到了相同的问题。所以我所做的是我使用了Anaconda提示符。它会自动将基本conda文件链接到所需的代理。只需在提示中键入“ conda --version”即可检查提示。然后输入“ conda install numpy”。瞧！你完成了。

Answer 2

降级到conda 4.5.5为我解决了这个问题。

戴上帽子：这是大约18个月来第三次conda更新导致错误，导致构建失败，并且还有很多其他问题。我猜想它会在某个时候被核心的conda人修复，也许是由第三方依赖关系的特定组合引起的，但是一种或另一种conda总是显得非常棘手。曾经有一个更新导致conda安装conda自行删除！

Answer 3

谢谢你，行得通！如果链接变旧，这是简化的副本：

导航到您的conda基本环境，如conda信息所提供。
打开文件lib / pythonX.Y / site-packages / conda / gateways / connection / init .py。其中X.Y是python主要版本。

将函数“ should_bypass_proxies_patched”替换为：

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)

Answer 4

这个问题仍然存在-在我安装新的Windows 10和最新稳定的Anaconda（2018.12）的新Windows 10上开始发生。在“ conda install -c conda-forge xgboost”命令上获取“解决环境：失败”。我可以从基本渠道安装一些东西，例如。 'conda install numpy'

Answer 5

删除到C:\Users\maglk\.condarc，然后更新Conda。这将在Windows中解决。

conda update conda

Answer 6

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

Answer 7

我已经尝试解决这个问题一段时间了。最后，我发现您应该使用pip install而不是conda install。通常我们在Windows命令提示符中使用pip install，而在Anaconda Prompt中使用conda安装。但是对我来说，我通过在Anaconda提示符下使用pip install解决了这个问题。输出如下所示

Answer 8

我有同样的问题，我只是通过

解决了

1。卸载anaconda并下载最新版本

2。创建一个新环境，然后尝试在该环境中安装软件包

conda返回“解决环境：失败”
