npm install 安装，但 node_modules 为空
npm install installs, but node_modules is empty
我在 digital ocean 运行ning Ubuntu 16.04 上有一个虚拟机。我安装了节点和 git。我正在拉取我的存储库，并尝试安装所有依赖项。
I 运行 npm install 在我的项目文件夹中。一切看起来都安装正确。然后我尝试通过 运行ning node server.js 启动我的应用程序，我得到了各种 module not found errors。
当我查看 node_modules 时，目录是空的。
知道会发生什么吗？

可能是您的 package.json 文件不存在或没有 dependencies 或 devDependencies。
您必须将 Droplet 的内存从 512mb 增加到 1gb，至少为了安装 npm 模块。然后，如果需要，您可以返回到 512mb。这为我修好了。
另一个不需要增加 Droplet 内存的选项（或者，如果您不在具有该功能的服务器上）是单独或以小组的形式手动安装依赖项。在我的例子中，express 是我安装的最大的包，所以我用 npm install express 手动安装它，然后 运行 npm install 得到其余的。
