我在执行library(text2vec)
lda_model <- LDA$new(
n_topics = 10,
doc_topic_prior = 0.1,
topic_word_prior = 0.01
)
doc_topic_distr <-
lda_model$fit_transform(
x = m,
n_iter = 1000,
convergence_tol = 0.001,
n_check_convergence = 25,
progressbar = FALSE
)

时遇到此错误
真正奇怪的是，当我运行npm run build时，编译成功完成。
npm run watch这是我的package.json依赖项和脚本：
ERROR in rbz_bundle.js from UglifyJs
Unexpected token: punc (,) [xxx.js:102316,12]
由于一些不明原因，我无法解决此问题，我看到有人建议添加{

"uglify-js": "git+https://github.com/mishoo/UglifyJS2.git#harmony"答案 0 :(得分：0)
似乎webpack不支持这种方式webpack.optimize.UglifyJsPlugin
您可以尝试以这种方式使用：
const WebpackUglifyJsPlugin = require('webpack-uglify-js-plugin');
放入顶部以声明插件
module.exports.plugins.push(
new WebpackUglifyJsPlugin({
cacheFolder: path.resolve(__dirname, 'target'),
debug: true,
minimize: true,
sourceMap: false,
output: {
comments: false
},
compressor: {
warnings: false
}
})
);
