pm2不启动服务器上的应用程序进程configuration加载失败

我无法启动DigitalOcean（CentOS7）上的PM2，

[PM2] Process config loading failed [] 

完整的命令..

 bash-4.3# pm2 start ecosystem.config.js --env production [PM2][WARN] You are starting -1 processes in fork_mode without load balancing. To enable it remove -x option. [PM2][WARN] Applications api not running, starting... [PM2] Process config loading failed [] ┌──────────┬────┬──────┬─────┬────────┬─────────┬────────┬─────┬─────┬──────────┐ │ App name │ id │ mode │ pid │ status │ restart │ uptime │ cpu │ mem │ watching │ └──────────┴────┴──────┴─────┴────────┴─────────┴────────┴─────┴─────┴──────────┘ Use `pm2 show <id| 

我的生态系统是..

 const nodeEnv = process.env.NODE_ENV || 'development'; if (nodeEnv === 'development') { require('dotenv').config(); } const maxMemory = process.env.WEB_MEMORY || 80; const base = { source_map_support: true, node_args: [ '--optimize_for_size', '--max_old_space_size=400', '--gc_interval=100', ], instances: process.env.WEB_CONCURRENCY || -1, exec_mode: 'fork', max_memory_restart: `${maxMemory}M`, }; module.exports = { apps: [ Object.assign({}, { name: 'api', script: 'api/index.js', env: { NODE_ENV: nodeEnv, PORT: process.env.PORT || 3000, API_MONGO_URL: process.env.API_MONGO_URL || 'mongodb://localhost', JWT_SECRET: process.env.JWT_SECRET || 'AA', SALT_WORK_FACTOR: process.env.SALT_WORK_FACTOR || 8, }, env_production: { NODE_ENV: "production", API_MONGO_URL: `mongodb://${process.env.MONGODB_PORT_27017_TCP_ADDR}:${process.env.MONGODB_PORT_27017_TCP_PORT}/swarmbot`, }, }, base), ], }; 

而没有日志..
