我正在运行build-nodejs-npm-installation-package-scratch的示例。而不是上传到npm存储库我把它放在Github上并尝试通过npm下载它。我运行npm install git+https://github.com/t2wu/replaceme.git并获得以下内容：
npm ERR! Error: ENOENT, chmod '/private/tmp/node_modules/replaceme_tim/replaceme.js'
npm ERR! If you need help, you may report this *entire* log,

我有一个package.json，我无法弄清楚出了什么问题。
编辑：我可以安装Express OK，但我无法安装练习模块
