python - 全新重新安装 Anaconda 失败 - 删除 Anaconda 与系统之间的所有冲突

Question

在更新过程中破坏了我的 Anaconda 环境(问题描述 here)后，我决定尝试重新安装 Anaconda。然而，尽管经过数小时的研究和错误查找，我还是未能安装 Anaconda。

我的问题是如何让我的系统恢复到 Anaconda 不会与我的系统发生冲突的状态。

在下面查找详细信息。

我的步骤如下:

• 我卸载了 Anaconda。
• 我下载了最新版本的 Anaconda 并安装了它。不幸的是，没有安装 Anaconda 提示符的可执行文件，Anaconda 也没有出现在开始菜单中。该问题已部分解决 here
• 我卸载了 Anaconda 并安装了 Miniconda。
• Miniconda 安装成功。我按照建议安装了 anaconda-clean here并运行它。
• 我卸载了 Miniconda，并确保 PATH 中没有出现 python 安装。
• 我删除了涉及 Python 的注册表项
• 我从 PATH 中删除了所有包含属于 Qt5 的文件的目录
• 我检查了 AppData 中没有出现 Python 和 Anaconda
• 我尝试再次安装 Anaconda，但出现与上述相同的失败。
• 我卸载了 Anaconda 并安装了 Miniconda。
• 我安装了 anaconda-navigator
• 我尝试安装 Glueviz，但失败了
• 我删除了由此产生的不一致，并逐个安装了软件包
• 我在安装 ipykernel 时遇到了问题，完整输出如下。

Here讨论这个问题的帖子很长。我为完成安装而采取的许多步骤都受到了该主题中帖子的启发，但我没有成功。请注意，我也在链接的线程中发布了我的问题。如果我得到 Anaconda 开发人员的帮助，我会确保答案也发布在这里。

我相信我的系统一定处于某种阻碍我安装 Anaconda 的状态。所有描述的问题似乎都很常见，但到目前为止，所建议的解决方案都不适合我。我已经没有想法了，对我(以及其他有同样问题的人)可以采取的一系列步骤感兴趣，以便将我的系统转移到与 Anaconda 不冲突的状态。

Answer 1

暂时禁用我的防病毒程序对我来说很有效。我正在使用 Windows 10 内置的防病毒程序。

打开 Windows Defender 安全中心并关闭实时保护。安装ipykernel包，再次开启实时保护。

此后，到目前为止我还没有遇到任何进一步的问题。
