After the promotion of webpac4, the node did not make an error, but the following error appeared on the page - Codes Helper

distinguish between modulesCfg.dev and modulesCfg.prod file lists to prevent overwriting other people"s js or old pages
configure only the portal files you are developing within modulesCfg.prod

AddEntryFile (modulesCfg.dev);

now all entry files use index.entry.js files as entry files
only reads the entry file path from the modulesCfg.js, and generally does not need to package all the pages, so it is risky not to deal with it for the time being.
Optimization: if it is a page, configSingleEntry the singlefile directly. If it is a module, add all the pages of the module
