configuration has an unknown property "optimization"
my project has been unable to run. Other people in the company can. I would like to ask why. I suspect that the version of webpack is wrong, but it is "webpack": "^ 4.23.1" in package.json. I don"t know how to solve it. I hope a boss can help solve it
webpack paste the related configuration
optimization: {
splitChunks: {
cacheGroups: {
commons: {
test: /[\\/]node_modules[\\/]/,
// cacheGroupKey here is `commons` as the key of the cacheGroup
name(module, chunks, cacheGroupKey) {
const moduleFileName = module.identifier().split('/').reduceRight(item => item);
const allChunksNames = chunks.map((item) => item.name).join('~');
return `${cacheGroupKey}-${allChunksNames}-${moduleFileName}`;
},
chunks: 'all'
}
}
}
