Recently, after upgrading the nodejs version to v18.7.0, the project report digital envelope routes::unsupported was launched. After many searches, the solution was finally found.

reason:

node.js version problem

Because of the recent release of OpenSSL 3.0 in node.js V17, OpenSSL 3.0 adds strict restrictions on allowed algorithms and key sizes, which may have some impact on the ecosystem. Therefore, previous projects will report an error after upgrading the nodejs version

Solution:

Method 1:

export NODE_OPTIONS=--openssl-legacy-provider

Method 2:
Modify package.json, add set NODE_OPTIONS=–openssl-legacy-provider before the relevant build command

"scripts": {
   "serve": "SET NODE_OPTIONS=--openssl-legacy-provider && vue-cli-service serve",
   "build": "SET NODE_OPTIONS=--openssl-legacy-provider && vue-cli-service build"
},
