conda 创建环境后，却不能激活环境

我怒了！！
气死我了！！！
每次安装Anaconda,都会有不同的问题出现

这一次的问题比较奇怪，网上没有找到案例，我也记一下，帮助大家

错误反馈：

(base) PS C:\Users\Nan> conda activate webtest

An unexpected error has occurred. Conda has prepared the above report.

If submitted, this report will be used by core maintainers to improve
future releases of conda.
Would you like conda to send this report to the core maintainers?

解决方法：
可以升级一下conda就好了

conda update -n base conda

？？？
干！
服了，浪费了我一个上午
