1、config/index.js文件下

npm install --save-dev compression-webpack-plugin@1.1.12 其他版本估計不匹配

2、要在nginx.conf文件中配置gzip才行

gzip  on;
    gzip_types text/plain application/javascript application/x-javascript text/javascript text/css application/xml application/x-httpd-php;
    #image/jpeg image/gif image/png;
    gzip_min_length 1k;
    gzip_comp_level 5; 
    gzip_buffers 16 8k;
    gzip_http_version 1.1;
    gzip_disable "MSIE [1-6]\.";
    gzip_vary on;
