包无法安装在项目目录中

Question

我尝试在我的项目目录(~/WebstormProjects/untitled3) 中安装一个包并得到他的以下消息

注意它在我的用户目录（Users/Nick/package.json）而不是我的项目目录中寻找 package.json

这是我的 npm-debug.log：

-- 好的，我已经删除了 /Users/Nick/package.json，但现在包安装在 /Users/Nick/node_modules 中

Answer 1

您的目录中已有package.json，但未正确配置。尝试检查它，或在此处发布它，我们会提供帮助。

似乎/Users/Nick/package.json 是有问题的文件 - 尝试删除它，除非它存在的原因。

供参考：

1. 当我刚刚尝试安装到一个空目录时 - 安装正常。
2. 当我删除并创建了一个空的package.json - 得到了同样的错误。 :)

编辑：鉴于您的编辑，试试这个：

NPM Installs Package Outside Current Directory

Answer 2

试试npm install express --save-dev
