在package.json中包含依赖项的问题

标签: javascript node.js

为什么在package.json中包含依赖项时如

"dependencies": {
    "nodemailer": "*"
 }

并正在运行

npm install

不安装软件包,而是执行

npm install nodemailer

好吗?

在两个实例中,返回的消息是

WARN Invalid name: "try node mailer"
WARN email No description
WARN email No repository field
WARN email No README field
WARN email No license field

但仅在第二个实例中,node_modules目录使用包

填充

我建议您使用其他一些版本匹配范围并避免使用asterix,根据规格@page:https://docs.npmjs.com/files/package.json#dependencies

我用这个做得很好:

{
  "name": "test",
  "version": "1.0.0",
  "description": "my test",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "dependencies": {
    "nodemailer": "~2"
  },
  "author": "",
  "license": "ISC"
}

希望能帮到你

您可以尝试""而不是使用通配符。否则这似乎有效:

{
  "name": "testr",
  "version": "1.0.0",
  "main": "main.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "dependencies": {
    "nodemailer": "^4.0.1"
  },
  "author": "",
  "license": "ISC"
}
