python - Conda 环境创建：由于 CondaVerificationError 无法创建 conda 环境

问题描述

我有一个私人 python 存储库，我的客户可以下载包。Linux 客户端可以毫无问题地从此私有存储库安装软件包。

Linux客户端conda版本：4.3.30

但是，Windows 客户端无法从私有存储库安装包。

Windows 客户端 conda 版本：4.3.30

错误是：CondaVerificationError: The package for ncurses located at C:\Anaconda3\pkgs\ncurses-6.1-he6710b0_1 appears to be corrupted. The path 'lib/terminfo' specified in the package manifest cannot be found.

比我做的：

conda clean -all

在该命令之后，当我尝试安装某些东西时，它没有给出错误并开始安装一堆东西。过了一会儿，它不再继续安装（当它到达“pip-18.1-py37_”时）。它也永远不会关闭安装过程。它卡在安装过程中。

有什么建议么？

编辑： 1-2 小时后，循环结束，我再次收到 CondaVerificationError：

CondaVerificationError: The package for ncurses located at C:\Anaconda3\pkgs\ncurses-6.1-he6710b0_1
appears to be corrupted. The path 'lib/terminfo'
specified in the package manifest cannot be found.

编辑 2：我尝试安装其他版本，例如“5.3.1、2018.12、2019.03”，但在我尝试创建环境并安装出现上述错误的软件包时，它们都失败了：

解决方案

我遵循了这里的建议：

https://stackoverflow.com/a/54761119/188963

即，我手动删除了 ncurses 文件夹：

find conda/envs -name "ncurses*" -exec rm -rf +

然后

conda install ncurses=6.1

之后，就没有问题了。
