npm WARN install Refusing to install hapi as a dependency of itself
提问by Nikola
I tried to do the following (per instructions from official site):
我尝试执行以下操作（根据官方网站的说明）：
mkdir hapi && cd hapinpm initnpm install hapi --save
mkdir hapi && cd hapinpm initnpm install hapi --save
But this gives me an error like this:
但这给了我这样的错误：
npm WARN install Refusing to install hapi as a dependency of itself
npm WARN install 拒绝安装 hapi 作为自身的依赖
Now, I made a new test folder called hapiTestand repeated the commands and then everything worked fine.
现在，我创建了一个名为的新测试文件夹hapiTest并重复这些命令，然后一切正常。
I tried the same process with a folder gulpand npm install gulp --save, and got the same error, so my conclusion is that I can't have the name of the folder be the same as the package that I want to install, but can someone back this statement up with some official documentation?
我对文件夹gulp和尝试了相同的过程npm install gulp --save，并得到了同样的错误，所以我的结论是我不能让文件夹的名称与我要安装的包相同，但有人可以支持这个声明有一些官方文件吗？

When you did the command npm init, there were probably some relevant questions you needed to answer. Specifically, the name of your module. When you use npm init, it assumes you want the name of the module you're creating to be called the name of the folder it is in.
当您执行命令时npm init，您可能需要回答一些相关问题。具体来说，就是您的模块的名称。当您使用 时npm init，它假定您希望正在创建的模块的名称被称为它所在文件夹的名称。
So it's not the name of the folderthat is stopping you from installing the dependency, it is the name of the npm modulethat you are creating.
因此，阻止您安装依赖项的不是文件夹的名称，而是您正在创建的npm 模块的名称。
Open the resulting package.jsonwithin your hapidirectory, and rename the module to something other than hapi. Here's an example 'package.json' that works, even when residing in a folder called hapi:
打开生成package.json的内部hapi目录，并重新命名模块比其他的东西hapi。这是一个有效的示例“package.json”，即使驻留在名为hapi的文件夹中：
{
"name": "hapi-test",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"dependencies": {
"hapi": "^7.5.2"
}
}
Added Note
添加注释
I've not been able to find any documentation thus-far explaining this phenomena in the context of npm; though it is a bit of a no-brainer. Requiring modules with the same name within the same application would conflict with the CommonJSphilosophy.
到目前为止，我还没有找到任何文档来解释 npm 上下文中的这种现象；虽然这有点不费吹灰之力。在同一个应用程序中要求具有相同名称的模块会与CommonJS哲学相冲突。

The name of your module is same as the module you are trying to install. NPM thinks that you are installing the module to itself. Change the name of your module and it will install perfectly.
您的模块名称与您尝试安装的模块名称相同。NPM 认为您正在为自己安装模块。更改模块的名称，它将完美安装。

The issue can be simply explained as follows
the name of your package or module in package.jsoncannot be same as that of the package or module you are trying to install.
该问题可以简单地解释如下
：您的包或模块的名称package.json不能与您尝试安装的包或模块的名称相同。
Here hapiis the name of your module and you are trying to install a module with name hapiwith npm install hapi --save
这hapi是您的模块的名称，您正在尝试安装名称hapi为npm install hapi --save
