Could you provide more information about this error? Like your operation (start taosd?), error information displayed on the screen? Have you installed taosd before and this time you installed a new version?

有人解决嘛

Could you provide more information about the error? How could we repeat this error? Such information can help us figure out the problem.

在上述环境下，按照rust的example里的Readme里写的命令执行，出现这个错误。

您在/usr/local/taos/driver/ 下面能找到类似 libtaos.so.1.6.3.0 以及在/usr/lib/下面能找到libtaos.so.1 （会软连接到/usr/local/taos/driver/下面的那个libtaos.so) 和 libtaos.so 这个文件吗？

[songtianyi]

# find . -name libtaos.so*
./usr/lib/libtaos.so.1
./usr/lib/libtaos.so
./usr/local/taos/driver/libtaos.so.1.6.3.0

[fangpanpan]

find . -name libtaos.so*

./usr/lib/libtaos.so.1
./usr/lib/libtaos.so
./usr/local/taos/driver/libtaos.so.1.6.3.0

那您看看libtaos.so.1 的软连接是否正确连接到了最下面的libtaosso.1.6.3.0?

[songtianyi]

find . -name libtaos.so*

./usr/lib/libtaos.so.1
./usr/lib/libtaos.so
./usr/local/taos/driver/libtaos.so.1.6.3.0

那您看看libtaos.so.1 的软连接是否正确连接到了最下面的libtaosso.1.6.3.0?

是的

lrwxrwxrwx 1 root root 41 10月 30 10:53 ./usr/lib/libtaos.so.1 -> /usr/local/taos/driver/libtaos.so.1.6.3.0

你们ci用的啥环境

[fangpanpan]

你们ci用的啥环境

ubuntu 和centos 都用。通常这个动态库是libtaos.so 软连接到libtaos.so.1, libtaos.so.1 软连接到 /usr/local/taos/driver/libtaos.so.1.6... 现在您的动态库文件存在，那就是找不到了。您可以参考一下这个添加路径https://github.com/taosdata/TDengine/issues/484
