如果发生错误 Exception in thread "main" java.lang.UnsatisfiedLinkError: no taos in java.library.path 请检查是否安装 TDengine 客户端安装包或编译 TDengine 安装。如果确定已经安装过还出现这个错误，可以在命令行 java 后加 -Djava.library.path=/usr/lib 来指定寻找共享库的路径。

If you encounter the error Exception in thread "main" java.lang.UnsatisfiedLinkError: no taos in java.library.path, please check whether the TDengine client package is installed or TDengine is compiled and installed. If you are sure it is installed and still encounter this error, you can add -Djava.library.path=/usr/lib after the java command to specify the path to the shared library.
