在流浪汉上安装npm

Question

我尝试以两种方式安装和使用npm，但只得到了错误。

正常安装npm：

vagrant@precise64:~$ npm install
npm ERR! Couldn't read dependencies.

npm ERR! Error: ENOENT, no such file or directory '/home/vagrant/package.json'
npm ERR! You may report this log at:

正在尝试安装最新版本：

vagrant@precise64:~$ npm install -g npm@latest
npm http GET https://registry.npmjs.org/npm

我应该在创建此package.json文件之前安装什么并使其正常工作？

Answer 1

npm看起来已经安装好了。转到您的项目根目录，然后：

npm init

它将引导您创建一个package.json文件，然后您可以

npm i whateverpackageyouwant

尽情享受吧。
