【问题描述】：

我正在尝试使用 node-forever，但尝试启动它时出现错误。

我将此文件命名为 start.js

var forever = require('forever-monitor');

  var child = new (forever.Monitor)('app-index.js', {
    'silent': false,
    'watch': true,
    'logFile': '/srv/http/mywebsite.com/logs/forever.log', // Path to log output from forever process (when daemonized)
    'outFile': '/srv/http/mywebsite.com/logs/node-stdout.log', // Path to log output from child stdout
    'errFile': '/srv/http/mywebsite.com/logs/node-stderr.log'  // Path to log output from child stderr
  });

  child.on('exit', function () {
    console.log('admin/app-index.js has exited');
  });

  child.start();

这是我运行 node start.js 时发生的情况

path.js:360
        throw new TypeError('Arguments to path.join must be strings');
              ^
TypeError: Arguments to path.join must be strings
    at path.js:360:15

    at Module._compile (module.js:456:26)
    at Object.Module._extensions..js (module.js:474:10)

有什么帮助吗？

【解决方案1】：

问题是你设置了watch: true，但没有设置watchDirectory。

默认watchDirectory 为空，但必须是字符串路径。这似乎没有很好的记录。

在您的情况下，以下应该可以解决您的问题：

var child = new (forever.Monitor)('app-index.js', {
    'silent': false,
    'watch': true,
    'watchDirectory': '/srv/http/mywebsite.com/public/',
    // ... etc.
});
