观察
[忽略这一点：我相信目前的版本是4.1，尽管看了几遍，但我每次尝试都会下载4.0.0。 ]
编辑 - 从另一台计算机下载4.1.1。这给出了相同的错误，也没有node_modules目录。
我上次在2月（在v4.0.0）看了这个，并在旧目录中运行相同的NPM命令。比较这两个目录，我在2月使用的目录有一个 node_modules 子目录，而当前的ZIP没有（git似乎也没有）。
这是我的问题，如果是这样，为什么今天ZIP文件中缺少 node_modules ？
答案 0 :(得分：2)
通常it's not recommended在发布到网络时包含node_modules。
相反，用户需要使用NPM安装软件包（在本例中）。只需运行 npm install ，NPM就会为您创建文件夹。
聚苯乙烯。 NPM从package.json
中找到模块列表
