yo command to scaffold is stuck

[shirleyshan17]

Hi,

Windows 10 64-bit`
My nodejs version is 10.22.1.
The npm version is 6.14.6.
yo version is 1.8.5.
I'm in china, so I have some network firewall problem. I installed the yeoman through cnpm(v 7.1).

I have a generator from OpenText called generator-csui-extension-21.1.0. (npm link )
Then I create a project folder and command 'yo csui-extension'.
I get lots of error messages like the following:

17 silly fetchPackageMetaData error for amodro-trace@^1.0.2 request to http://registry.cnpmjs.org/amodro-trace failed, reason: getaddrinfo EAI_AGAIN registry.cnpmjs.org registry.cnpmjs.org:80
18 silly fetchPackageMetaData error for csslint-stylish@^0.0.6 request to http://registry.cnpmjs.org/csslint-stylish failed, reason: getaddrinfo EAI_AGAIN registry.cnpmjs.org registry.cnpmjs.org:80
19 silly fetchPackageMetaData error for csso@^3.2.0 request to http://registry.cnpmjs.org/csso failed, reason: getaddrinfo EAI_AGAIN registry.cnpmjs.org registry.cnpmjs.org:80
20 silly fetchPackageMetaData error for eslint-config-defaults@^9.0.0 request to http://registry.cnpmjs.org/eslint-config-defaults failed, reason: getaddrinfo EAI_AGAIN registry.cnpmjs.org registry.cnpmjs.org:80

I don't know how to deal with it. Does it mean I need to install these things one by one manually?
I find there're many files in my project folder but there's nearly nothing in the project/node_modules folder.

The worse thing is that yo can't scaffold after that. If I create a new folder like project B and yo csui-extension again. There's nothing happened except create a few of empty folders in project B.

I tried to use 'yo doctor', it told me 'everything looks all right'.

Does anyone have similar problems? What can I do to deal with it?
