试图清理安装python（anaconda），获取与之前安装相关的错误

Question

每次我执行anaconda的干净安装时，我都会得到相同的冗长错误。我最好喜欢清除我的电脑中的任何python文件。我已经尝试了从删除路径变量，删除我的计算机残留文件夹/文件（除了.anaconda我没有在这里成功）删除注册表中的HKEY_CURRENT_USER \ Software \ Python键。我相信这个错误在我尝试安装第二个版本的python时开始发生（我有连续安装）。任何帮助将是惊人的，非常感谢！ `当前畅达安装：

Answer 1

首先，确保PIP和setuptools的是最新的，每this答案。

未来，使用venv来创建虚拟环境可能会有帮助，从而帮助消除依赖性问题。

这样创建一个新的虚拟环境：

python3 -m venv /path/to/new/virtual/environment 

需要Python 3.3或更大，但它看起来像你使用的3.6，所以你应该是好去。更多关于venv的信息可以在here找到。
