Python -m taichi example [anything] 跑不了

我的环境是Windows Powershell，pip安装了0.6.7并且确保能跑课堂slide里的短码，但是很遗憾跑不了内置的example。请问如何解决？以下是错误提示：

Hi, please use python -m taichi example mpm88.

犯了个低级错误不好意思 :stuck_out_tongue:
但这个指令还是不行，它总是说我给的案例在example里没有，只能是完整的地址。我把完整的地址黏贴过去依然不行：

抱歉，是bug，目前请直接从github拷贝examples文件夹下的代码运行

#7

感谢各位，我去github下载啦

#8

我之前也遇到了同样的问题，修改了…\site-packages\taichi\文件夹下main.py文件的下面一行代码之后就可以正常运行了

#9

没错，对于win应该是’\\‘而不是’/’，已经修复，将在v0.6.8中发布。
