我按照readme进行运行，报错如下

看起来是没有找到Taichi C API，需要设置环境变量 $TAICHI_C_API_INSTALL_DIR 包含 libtaichi_c_api.so。

还有就是不要直接跑 run_tests.py， 这是GitHub CI跑的脚本。你可以使用CMAKE编译所有的Tutorial，然后跑一下每个example。

或者按照Tutorial，跑个小例子。我自己根据Tutorial，自己写了一个小工程，你可以参考：here。

非常感谢，此外$TAICHI_C_API_INSTALL_DIR 放在.bashrc里就可以了是吗

#4

是的，不过记得使用命令 source ~/.bashrc，让环境变量起作用。
