node.js:为什么NODE_DEBUG = 1不起作用？(尝试调试require()错误)

我有一个像这样的目录结构:

project
  lib
    paperboy
    redis-client
    node-cookie
  srv
    main.js
  ...

我从项目目录启动main.js:

$ node srv/main.js

在main.js中,我可以这样做:

  paperboy = require('./lib/paperboy');

但是,这失败了:

  redis = require('./lib/redis-client');

同样,如果我在"项目"目录中启动交互式节点,我可以要求使用paperboy,但不能使用redis-client.我得到的错误是:

> require('./lib/redis-client')
Error: Cannot find module './lib/redis-client'
    at resolveModuleFilename (node.js:265:13)
    at loadModule (node.js:231:20)
    at require (node.js:291:14)
...

查看resolveModuleFilename()的源代码,它会尝试打印调试字符串,我看不到:

debug("looking for " + JSON.stringify(id) + " in " + JSON.stringify(paths));

我尝试通过导出NODE_DEBUG = 1来启用它,但在尝试要求时我仍然没有看到此调试打印.

在尝试打印这个调试时我做错了什么？第二,为什么paperboy加载得很好,但redis-client找不到？

lib目录从github解压缩.tar.gz文件,重新命名以匹配package.json文件中的模块名称.

你想要出口NODE_DEBUG=module,而不是=1
