本文记录了使用Anaconda过程中遇到的问题及解决方法。作者在更新conda后发现无法正常创建新环境和安装模块，尝试了多种解决方案最终通过安装旧版本conda恢复正常。

Anaconda通过conda update conda更新以后创建新环境，安装模块报错问题

有个包一直安不上，以为是Anaconda版本太久了，就用下面命令更新了一下

conda update conda

更新完conda不能正常使用了，发生了创建新环境和安装模块就会报错的情况

解决办法

重装肯定是最简单的解决办法，但是那么多环境，都是好不容易配出来的，再配一次我能气到把键盘吃掉
github/conda给出的一个方法，把conda回退到旧的可以用的版本
```
conda config --set allow_conda_downgrades true
conda install conda=4.6.14
```
很多人好评
我试了一下，没有用，循环报错，install再次报错

我需要正常的conda，但是没有正常的conda不能安装正常的conda

所以，我到独立的正常conda可执行文件下载了一个win版本的可执行文件

用可执行文件安装旧版本conda
```
<executable path> install -p <path to broken installation> conda=4.6.14
```
举个栗子，我是这样输入的

问题解决了，conda又能用了，这应该是最新版本conda 4.8的一个bug
