从 Anaconda 2.7 创建的 Python3 环境失败

Question

我安装了Anaconda 2，所以我的基本python版本是2.7。我可以使用

conda create --name new_27 python=2.7

激活后，环境将按预期工作。但是如果我安装 python 版本 3.x，它会失败。安装没有警告，我可以激活它。但是在那里运行任何内容都会产生以下错误消息(无论我运行什么，我总是收到相同的错误消息)

(py36) C:Usersist>pip list

Answer 1

看起来您的 Python 3 conda 环境可能正在尝试访问基本环境中的包。

这些步骤应该尝试通过删除Python 3环境来解决这个问题;清理任何残留的包;更新conda;然后重新创建环境。

conda env remove -n py36
conda clean -tipsy
conda update conda -y
conda create -n py3 python=3.6

如果这不起作用，您可能需要重新安装 Anaconda。
