我在运行Ubuntu 16.04的数字海洋上有一台虚拟机。我安装了node和git。我正在拉回我的仓库，并尝试安装所有依赖项。
我在项目文件夹中运行npm install。一切看起来都正确安装。然后我尝试通过运行node server.js来启动我的应用，并获得各种module not found errors。
当我查看node_modules时，目录为空。
任何想法可能会发生什么？

您必须将Droplet的内存从512mb增加到1gb，至少在安装npm模块时是这样。然后，如果你愿意，你可以回到512mb。这为我解决了。

可能是您的public class TailRecursiveOddonacci {
public long tailOddonacci(int n) {
if (n <= 3) {
return 1;
}
return tailOddonacciRecursion(0, 1, 2, n);
}
private long tailOddonacciRecursion(int a, int b, int c, int count) {
if(count <= 0) {
return a;
}
return tailOddonacciRecursion(b, a+b, a+b+c, count-1);
}
}
文件不存在或没有package.json或dependencies。

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），则需要单独或以小组手动安装依赖项。在我的情况下，express是我正在安装的最大包，所以我用npm install express手动安装，然后运行npm install来完成剩下的工作。
