npm throws ENOENT warnings on every install/uninstall/ls
提问by Rice
I am trying to do npm install on a Windows 7 shell for some js test development packages directly in a source code repository I cloned locally, in this case karma, chai and mocha.. I consistently get the following errors when trying to install, uninstall other packages.
我正在尝试在 Windows 7 shell 上为一些 js 测试开发包直接在我本地克隆的源代码存储库中执行 npm install，在这种情况下是 karma、chai 和 mocha .. 我在尝试安装、卸载时始终遇到以下错误其他包。
npm WARN ENOENT ENOENT, open '..SourceDirectory\package.json'
npm WARN EPACKAGEJSON ..SourceDirectory\ No description
npm WARN EPACKAGEJSON ..SourceDirectory\ No repository field.
npm WARN EPACKAGEJSON ..SourceDirectory\ No README data
npm WARN EPACKAGEJSON ..SourceDirectory\ No license field.
npm lsalso yields
npm ls也产生
npm ERR! error in ..SourceDirectory\: ENOENT, open '..SourceDirectory\package
.json'
I did pull the beta of the Windows npm upgrade from
我确实从
because I was running into the file system path length error. I do not have a package.json dependency list located in the warnings' path. Is there a configuration step I missed?
因为我遇到了文件系统路径长度错误。我没有位于警告路径中的 package.json 依赖项列表。有没有我错过的配置步骤？

Error message might be caused by missing package.jsonfile. Change directory to your project's local directory, as an example (instead, use current working directory of your project):
错误消息可能是由package.json文件丢失引起的。例如，将目录更改为项目的本地目录（而是使用项目的当前工作目录）：
cd /var/www/nodeBot
Following string will write package.json:
以下字符串将写入package.json：
npm init
Answer menu-driven questions or use --yesto blast past them. Then press enter at the end to write out the file. You might see something like:
回答菜单驱动的问题或用于--yes解决它们。然后在最后按回车键写出文件。您可能会看到类似以下内容：
Wrote to /usr/local/bin/package.json:
{
"name": "bin",
"version": "1.0.0",
"description": "",
"main": "index.js",
"dependencies": {
"twit": "^2.1.1"
},
"devDependencies": {},
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"keywords": [],
"author": "",
"license": "ISC"
}
npmis node.js's package manager. package.jsonbecomes npm's configuration or settings file. The twitdependency was a program installed into my project dir. npm install twit
npmisnode.js的包管理器。package.json成为npm的配置或设置文件。该twit依存度安装到我的项目目录的程序。npm install twit
If a package.json file exists in your project's directory, you can use a text editor to fill in empty data fields that can also cause error messages.
如果您的项目目录中存在 package.json 文件，您可以使用文本编辑器来填充也会导致错误消息的空数据字段。
Find the descriptionfield in the package.jsonfile and manually add a description:
description在package.json文件中找到该字段并手动添加描述：
"description": "This is my latest disruptive technology app.",
In licensefield you can add ISCwhich basically means open source project:
在license字段中，您可以添加ISC这基本上意味着开源项目：
"license": "ISC"

I had this issue myself, all i did was to remove the package-lock.jsonfile and now it works. Hope this helps someone.
我自己也遇到了这个问题，我所做的就是删除该package-lock.json文件，现在它可以工作了。希望这可以帮助某人。

There could be a problem with your "engines" value in the parent package.json file.
父 package.json 文件中的“engines”值可能有问题。
For example, i had
例如，我有
"engines" : {
"node": ">=6.10.0",
"npm": ">=4.3.0"
}
I removed the "npm" key and it just worked (Scratching my head....)
我删除了“npm”键，它就起作用了（挠头……）

I also faced the same problem but i was doing a silly mistake
我也遇到了同样的问题，但我犯了一个愚蠢的错误
if your npm is installed properly then problem can be confusion between developer to select the current directory to install .js packages. Actually installing anything using npm requires Package.json file in the directory you want to install your package
如果你的 npm 安装正确，那么问题可能是开发人员选择当前目录来安装 .js 包之间的混淆。实际上使用 npm 安装任何东西都需要你要安装包的目录中的 Package.json 文件
eg: npm install abcd
例如： npm install abcd
now if you want to install abcd package via npm make sure you are in the right directory using terminal
现在，如果您想通过 npm 安装 abcd 包，请确保您使用终端位于正确的目录中
eg: my npm directory on my mac is
例如：我的 mac 上的 npm 目录是
/Users/myMac/node_modules/assert-plus/package.json
/Users/myMac/node_modules/assert-plus/package.json
so if make sure you are in directory
所以如果确保你在目录中
/Users/myMac/node_modules/assert-plus
/Users/myMac/node_modules/assert-plus
select this directory via terminal and then write npm install abcd
通过终端选择这个目录，然后写 npm install abcd

You need to switch into the directory that you're working and then run:
您需要切换到您正在工作的目录，然后运行：
npm -init
After running that, continue to press enter until you get to the end.
运行后，继续按回车键直到结束。
