Question

我正在尝试为我的开发服务器设置pm2，它似乎已启动，但是在进入端口3000的站点时，它说无法访问拒绝连接。我检查了我的pm2日志，并显示

SyntaxError：/var/www/html/ucdirectorapp/src/index.js：意外令牌（33：4） 0 | ucdirector-dev | 31 | ReactDOM.render（ 0 | ucdirector-dev | 32 | 0 | ucdirector-dev | > 33 | 0 | ucdirector-dev | | ^ 0 | ucdirector-dev | 34 | ，document.getElementById（'root'））; 0 | ucdirector-dev | 35 |

所以我认为这与我的口译员有关。

我已经编译并创建了一个构建文件夹。

我已将解释器指向./node_modules/@babel/cli/bin/babel.js 甚至./node_modules/babel-cli/bin/babel-node.js。

我尝试重新安装babel-cli。我尝试删除我的node_modules并重新安装所有内容。

我尝试在全球范围内安装babel-cli。


//this is my pm2 config file

module.exports = {
    apps: [{
        name: "ucdirectorapp",
        script: "./src/index.js",
        watch: [
            "./build",
            "./public",
            "./src"
        ],
        watch_delay: 1000,
        ignore_watch: ["node_modules"],
        watch_options: {
            "followSymlinks": false
        },
        env: {
            name: 'ucdirector-dev',
            NODE_ENV: 'development',
            "PORT": 3000,
        },
        interpreter: "./node_modules/babel-cli/bin/babel.js"

    }],
};

//my webpack config uses these presets and plugins for js

 test: /\.(js|jsx)$/,
                use: [
                    {
                        loader: "babel-loader",
                        options: {
                            presets:[ "@babel/preset-env", "@babel/preset-react"],
                            plugins: [
                                "@babel/plugin-syntax-dynamic-import", '@babel/plugin-proposal-class-properties'
                            ]
                        }
                    }
                ],

//in my package.json these are the dependecies i'm using for babel

    "babel-plugin-transform-runtime": "^6.23.0",

//this is what i have in dev dependecies

    "babel-preset-stage-0": "^6.24.1",


//and this is the script that I am using 

 "pm": "pm2 start config/server/pm2.config.js --watch",

我希望站点在端口3000上启动，并且语法错误将被删除。但我看到此语法错误。我猜想它不能收回反应类。

我发现生态系统.config.js可以使用解释器./node_modules/.bin/babel-node，但是在他们的文档中说，只有在以下环境中运行：

“ 叉子”模式

请记住，这些命令仅适用于fork_mode。如果要运行PM2群集，请参阅下面的替代方法。

您可以在其页面中查看所有信息。

PM2 Interpretor未在我的开发环境中使用Babel进行React App
