[Solved] NPM Start Project Error: ‘Error: error:0308010C:digital envelope routines::unsupported’

Reason: the version of node is higher than 16, the version of the project is not higher than 16, and OpenSSL is updated after node17.

Solution:

Method 1:

Modify the environment variable at the command line: $env:NODE_OPTIONS="--openssl-legacy-provider"
In the start project: yarn start
Method 2.
Use nvm to modify the node to a version no higher than 16

NPM start project error: cannot find module ‘webpack’ problem solution

First install cnpm and then use cnpm i to install the package when stuck and then force to end the download and then install node_modules again after the error error, start the project when npm run serve reported the following error.
The correct approach: If you force to interrupt the download, you should remove the node_modules and reinstall them, no error after the end of the installation means success
