child_process 子进程

常见问题

spawn npm ENOENT

示例 如执行

const { spawn } = require("child_process");
const path = require("path");
const child = spawn("npm", ["run", "build"], {
  cwd: path.resolve(__dirname)
});

报错 spawn npm ENOENT

参考 (opens new window)

需要基于运行的系统环境配置 npm

const npm = process.platform === "win32" ? "npm.cmd" : "npm";
const child = spawn("npm", ["run", "build"], {
  cwd: path.resolve(__dirname)
});
