软件包无法安装在项目目录中

Question

我尝试在我的项目目录中安装一个包（〜/ WebstormProjects / untitled3）并得到以下消息

注意它在我的用户目录中找到一个package.json（Users / Nick / package.json）而不是我的项目目录

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

Answer 1

您的目录中已有package.json，但配置不正确。尝试检查，或在此处发布，我们将提供帮助。

似乎/Users/Nick/package.json是违规文件 - 尝试将其删除，除非有理由将其存在。

供参考：

1. 刚才我尝试安装到空目录中 - 安装正常。
2. 当我删除并创建一个空的package.json时 - 得到了同样的错误。 ：）

修改：根据您的修改，请尝试以下操作：

NPM Installs Package Outside Current Directory

Answer 2

尝试npm install express --save-dev
