Hey rainy_uestc,
I never installed PyVisa on my boxes. To exclude the influence of this SW-package you can try an installation of NI-VISA without PyVisa.
Good luck

Bodo,
I found it's a problems of version. I use your method and installed NI-VISA 14.0.0
successfully; and also I installed NI488.2-2.9.1 by using the same way.
really thank you for your help.
