Error: clean-webpack-plugin only accepts an options object.

TypeError: CleanWebpackPlugin is not a constructor

More than two errors belong to the same

Prior written like this:

const CleanWebpackPlugin = require("clean-webpack-plugin");

plugins:[
 new CleanWebpackPlugin(['dist']),   
]

Then error: TypeError: CleanWebpackPlugin is not a constructor

Later wrote:

const {CleanWebpackPlugin} = require("clean-webpack-plugin");

plugins:[
 new CleanWebpackPlugin(['dist']),   
]

Continue error: Error: clean-webpack-plugin only accepts an options object.

Finally, write:

const {CleanWebpackPlugin} = require("clean-webpack-plugin");

plugins:[
 new CleanWebpackPlugin(),   
]

 Successful operation ~

 

Two:

1, new CleanWebpackPlugin () in not write parameters, 
2, need {}
