The above information was obtained by entering the command npm audit, npm audit fix. And since denial of service was displayed, it was judged that the service was stopped, and the user entered npm uninstall mem or entered ncu, ncu-u to try to solve the problem, but the problem was not solved.
I also referred to here , but it has not been resolved did. .

Supplemental information (FW/tool version etc.)

npm -v->6.13.1

  • Answer # 1


    Denial of service is displayed and it is determined that the service has been stopped

    This judgment is wrong.npm auditis a tool for determiningvulnerabilities, so there are also vulnerabilities that are difficult to cause.

    Andnpm updatemay fix a new version, but it may not be resolved if you lock into the old version in the library.

    In the first place,npmis not normally executed from outside, so even if there is a DoS vulnerability, the risk of actually affecting it is low. Ifnpm updatedoes not solve it, you can leave it alone.
