踩坑指南！anaconda新建环境出错解决！又是猛男落泪的一天！

我在配置环境时出现一些问题，冲动之下直接删除了anaconda/envs/xxx下的那个环境包，在重新使用conda create创建环境时，就出现了下面的问题：(忘记截图了，在网上看到类似的错误copy过来作为错误代码示例)

尝试过卸载重装anaconda，重新下载anaconda，甚至进入到 D:\Anaconda3\lib\json\decoder.py 这个里面去找那个奇葩的double quotes问题，均无果！！！(周末就要报告，我周四环境还没配好，嘤嘤嘤)

后来终于找到一个大神的解答，亲测有效：

I have tried to find solutions for almost five days. And I finally solved my problems with the help of others.
For my case, when I reinstalled anaconda on my machine, a .condarc file was automatically generated. Then error occurred when I used conda install and conda create command.
After I delete .condarc file, everything goes well. Hope this way can help others with the same problem. Use the following command to check the path of the .condarc file, then delete it/them.
conda config --show-sources

意思是，用conda config --show-sources查出.condarc文件的位置在哪里，然后把这个文件删掉就行了，这个文件是我们在重新换源的时候出现的。
bingo问题解决，希望每次记录踩坑心得可以让我攒攒人品，少遇环境bug。
