安裝mars3D時需要安裝copy-webpack-plugin插件
然后在vue.config.js進行配置 運行報錯ERROR Error: [copy-webpack-plugin] patterns must be an array
pattern必須是一個數組
當前node版本為12.2.0

const plugins = [// 標識cesium資源所在的主目錄，cesium內部資源加載、多線程等處理時需要用到new webpack.DefinePlugin({CESIUM_BASE_URL: JSON.stringify(path.join(config.output.publicPath, cesiumRunPath))}),// Cesium相關資源目錄需要拷貝到系統目錄下面（部分CopyWebpackPlugin版本的語法可能沒有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改為如下

const plugins = [// 標識cesium資源所在的主目錄，cesium內部資源加載、多線程等處理時需要用到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') }])];

運行成功
