我正在尝试为我的开发服务器设置 pm2，它似乎已启动，但在访问我的端口 3000 的站点时，它说无法访问拒绝连接。我检查了我的 pm2 日志，它说

语法错误：/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翻译有关。

我已经编译并制作了一个构建文件夹。

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

我试过重新安装 babel-cli。我试过删除我的 node_modules 并重新安装所有东西。

我已经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"],

                                "@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-proposal-class-properties": "^7.4.4",
    "babel-plugin-async-to-promises": "^1.0.5",
    "babel-plugin-transform-class-properties": "^6.24.1",
    "babel-plugin-transform-runtime": "^6.23.0",
    "babel-preset-env": "^1.7.0",
    "babel-preset-react": "^6.24.1"

//this is what i have in dev dependecies

 "@babel/core": "^7.4.5",
    "@babel/plugin-transform-runtime": "^7.4.4",
    "@babel/preset-env": "^7.4.5",
    "@babel/preset-react": "^7.0.0",
    "babel-core": "^6.26.3",
    "babel-loader": "^8.0.6",
    "babel-polyfill": "^6.26.0",
    "babel-preset-es2015": "^6.24.1",
    "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",

我希望该站点在端口 3000 上运行，并且将删除语法错误。但我看到了这个语法错误。我猜它不会重新识别反应类。

我发现生态系统.config.js 可以使用解释器 ./node_modules/.bin/babel-node 但在他们的文档中说只有当它运行在：

“分叉”模式

请记住，这些命令仅适用于 fork_mode。如果您想运行 PM2 集群，请参考下面的替代方案。

您可以查看他们页面中的所有信息。
