创建环境 Python-3.5 错误

Question

我刚刚在 Windows 10 中安装了 Anaconda（安装 Python 3.6）......它运行良好。然后我尝试创建一个 Python 3.5 环境：

% conda create -n py35 python=3.5 anaconda

但验证过程失败。我已经尝试了两次...验证列出了 702 错误如下...这是前三个（我已将“用户名”替换为我的用户名）：

CondaVerificationError: pyqt 的包位于 C:\Users\

<UserName>\AppData\Local\Continuum\anaconda3\pkgs\pyqt-5.6.0-py35hd46907b_5
appears to be corrupted. The path 'Lib/site-packages/PyQt5/Enginio.pyd'
specified in the package manifest cannot be found.

这应该很简单：在 Windows 10 中安装环境... 然而它失败了......我错过了一步吗？路径变量未设置？

Answer 1

有同样的问题。并帮助解决了这个link。 conda clean --packages --tarballs

Answer 2

上一个答案的另一种选择：

conda clean --all

这将删除索引缓存、锁定文件、未使用的缓存包和 tarball。
