javascript - Chart.js 未随 NPM 安装

Question

我正在尝试安装 Chart.js 。他们关于如何使用 NPM 安装软件包的文档位于:http://www.chartjs.org/docs/latest/getting-started/installation.html

它说要使用 NPM 输入以下内容来安装。

npm install chart.js --save

但是，这对我不起作用。当我尝试使用 NPM 安装 Chart.js 时，我的控制台中出现以下错误。

C:\Users\Hashim AHmed\Desktop\Hashim\coding\Project_PlasmaBird\yahoo_finance>npm install chart.js --save
npm ERR! not a package (MY PROJECT DIRECTORY)\yahoo_finance\chart.js

编辑:正如一些人指出的，错误可能存在于我的 Package.json 中，所以这里是我的包文件的代码(我已经审查了一些私有(private)信息):

{
  "name": "projectplasma",
  "version": "1.0.0",
  "description": "projectplasma",
  "main": "index.js",
  "dependencies": {
    "colors": "^1.1.2",
    "yahoo-finance": "^0.3.2"
  },
  "devDependencies": {},
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "repository": {

    "url": "git+https://github.com/(my username)/(my repo).git"
  },
  "keywords": [

  "bugs": {
    "url": "https://github.com/(myusername)/(my repo)/issues"
  },
  "homepage": "https://github.com/(my username)/(my repo)#readme"
}

你知道这里出了什么问题吗？我完全按照文档所说的做。如果有人可以测试安装它以查看它是否有效，那就太好了。谢谢

您的目录中需要有 package.json 文件才能将此 chart.js 模块保存在本地。

要创建 package.json 文件，请使用以下命令，

npm init(它会问你几个问题，并在最后创建文件)。

创建 package.json 后，尝试执行 npm install Chart.js --save 命令并查看它是否有效。

希望这有帮助!
