我刚刚开始使用npm,据我所知,npm install
命令应该会自动更新package.json
文件,但遗憾的是,我没有。{/ p>
我在OSX上并在一个名为npmtest的新目录中执行了以下操作:
$ ls # let's first confirm the folder is empty
$
$ npm init --y
Wrote to /Users/kramer65/Downloads/npmtest/package.json:
{
"name": "npmtest",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"keywords": [],
"author": "",
"license": "ISC"
}
然后我安装了下划线:
$ npm install underscore
npmtest@1.0.0 /Users/kramer65/Downloads/npmtest
└── underscore@1.8.3
npm WARN npmtest@1.0.0 No description
npm WARN npmtest@1.0.0 No repository field.
似乎安装得很好:
$ ls -l
total 8
drwxr-xr-x 3 kramer65 staff 102 Oct 18 17:47 node_modules
-rw-r--r-- 1 kramer65 staff 221 Oct 18 17:47 package.json
遗憾的是npm list
抱怨它不在package.json
文件中extraneous
标志:
$ npm list
npmtest@1.0.0 /Users/kramer65/Downloads/npmtest
└── underscore@1.8.3 extraneous
npm ERR! extraneous: underscore@1.8.3 /Users/kramer65/Downloads/npmtest/node_modules/underscore
我可以确认:
$ cat package.json
{
"name": "npmtest",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"keywords": [],
"author": "",
"license": "ISC"
}
问题是;为什么不在package.json
文件中输入?不应该自动进行吗?我在这做错了什么?欢迎所有提示!
答案 0 :(得分:2)
npm install
没有更新package.json文件,npm install *module name* --save
更新json
包。希望有所帮助。
