prerender-spa-plugin出现Failed to launch chrome 解决方案

 

在Linux （CentOS）系统下，打包带prerender-spa-plugin 这个预渲染插件的内容，出现如下报错

 

Error: Failed to launch chrome!

解决方案如下：

1、确保 prerender-spa-plugin 配置中不包含headless 和 inject配置项

new PrerenderSPAPlugin({
              routes: ["/future"],
              staticDir: path.join(__dirname, '../build'),
              renderer: new Renderer({
                renderAfterTime: 5000
              })
            })

2、在Linux 系统下安装依赖包，命令如下：

yum install libXScrnSaver atk java-atk-wrapper at-spi2-atk gtk3 libXt -y
