ERROR Error: [copy-webpack-plugin] patterns must be an array

安装mars3D时需要安装copy-webpack-plugin插件
然后在vue.config.js进行配置 运行报错ERROR Error: [copy-webpack-plugin] patterns must be an array
pattern必须是一个数组
当前node版本为12.2.0

const plugins = [
            // 标识cesium资源所在的主目录，cesium内部资源加载、多线程等处理时需要用到
            new webpack.DefinePlugin({
                CESIUM_BASE_URL: JSON.stringify(path.join(config.output.publicPath, cesiumRunPath))
            }),
            // Cesium相关资源目录需要拷贝到系统目录下面（部分CopyWebpackPlugin版本的语法可能没有patterns）
           new CopyWebpackPlugin({
                patterns: [
                { from: path.join(cesiumSourcePath, 'Workers'), to: path.join(config.output.path, cesiumRunPath, 'Workers') },
                { from: path.join(cesiumSourcePath, 'Assets'), to: path.join(config.output.path, cesiumRunPath, 'Assets') },
                { from: path.join(cesiumSourcePath, 'ThirdParty'), to: path.join(config.output.path, cesiumRunPath, 'ThirdParty') },
                { from: path.join(cesiumSourcePath, 'Widgets'), to: path.join(config.output.path, cesiumRunPath, 'Widgets') }
                ]
            })

new CopyWebpackPlugin改为如下

const plugins = [
            // 标识cesium资源所在的主目录，cesium内部资源加载、多线程等处理时需要用到
         new webpack.DefinePlugin({
                CESIUM_BASE_URL: JSON.stringify(path.join(config.output.publicPath, cesiumRunPath))
         }),
         new CopyWebpackPlugin([
	        { from: path.join(cesiumSourcePath, 'Workers'), to: path.join(config.output.path, cesiumRunPath, 'Workers') },
	        { from: path.join(cesiumSourcePath, 'Assets'), to: path.join(config.output.path, cesiumRunPath, 'Assets') },
	        { from: path.join(cesiumSourcePath, 'ThirdParty'), to: path.join(config.output.path, cesiumRunPath, 'ThirdParty') },
	        { from: path.join(cesiumSourcePath, 'Widgets'), to: path.join(config.output.path, cesiumRunPath, 'Widgets') }
        ])
 ];
