After downloading the official engineering documents   After iView Projcet, run NPM run Dev and an error will be reported, as shown above

A solution was found later:

In the webpack. * config file, modify it to the corresponding node according to your current node version

1 fs.open(‘./build/env.js‘, ‘w‘, function(err, fd) {
2     const buf = ‘export default "development";‘;
3     // node version problem
4     // fs.write(fd, buf, 0, buf.length, 0, function(err, written, buffer) {}); // node --version > v10.1.0
5     fs.write(fd, buf, function(err, written, buffer) {}); // node --version < v10.1.0
6 });
