pm2 无法启动脚本：

Question

我想在 Windows 中使用 pm2 启动我的脚本，但我收到错误： SyntaxError: Unexpected token ':'

我的开始脚本是 start:dev 到运行我说：pm2 start npm -- 'start:dev'

我的脚本：

"scripts": {
    "start": "NODE_ENV=production node dist/src/index.js",
    "build": "tsc -p . && ncp productionenv ./dist/src/.env",
    "start:dev": "npm run build:dev",
    "build:dev": "nodemon src/index.ts --exec ts-node src/index.ts -e ts,graphql",
    "test": "jest"
  },

完全错误：

Answer 1

您实际上是在运行自定义脚本，因此它需要运行以不同的方式：

pm2 start npm run start:dev

无论何时添加任何自定义脚本，npm run scriptname 都是要遵循的命令。如果您想了解更多信息，请查看 here.

此外，它应该是脚本的一部分：

"scripts": {
    "start": "NODE_ENV=development npm start",
    "start:dev": "npm start --watch",
    "start:debug": "npm start --debug --watch",
    "start:prod": "node dist/main",
  },

Answer 2

您可以使用以下方式来运行脚本 :

pm2 start npm --name "your-app-name" -- run "start:dev"

pm2 无法启动脚本：

pm2 can't start script with :

node.js
