試圖清理安裝python（anaconda），獲得與先前安裝相關的錯誤

Question

每次我做一個干凈安裝的anaconda我都會得到同樣冗長的錯誤。 我最喜歡清除我的計算機中的任何python文件。 我已經嘗試了從刪除路徑變量，到我的計算機搜索剩余文件夾/文件（除了.anaconda，我沒有成功）在regedit中刪除HKEY_CURRENT_USER \\ Software \\ Python鍵。 我相信當我嘗試安裝第二版python時會出現這個錯誤（我有連續安裝）。 任何幫助將是驚人的，非常感謝！ `目前的conda安裝：

Answer 1

首先，根據這個答案，確保pip和setuptools是最新的。

將來，使用venv創建一個有助於消除依賴性頭痛的虛擬環境可能會很有用。

創建一個像這樣的新虛擬環境：

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

需要Python 3.3或更高版本，但看起來你正在使用3.6，所以你應該很高興。 有關venv更多信息， venv 點擊此處 。
