Question

所以基本上这是package.json的json文件，我用npm install :(对于github上的angularfire-seed项目，如果有人想知道的话）

 {
  "name": "angularfire-seed",
  "description": "A starter project for Angular + Firebase with AngularFire",
  "version": "1.0.0",
  "homepage": "https://github.com/firebase/angularfire-seed",
  "repository": "https://github.com/angular/angular-seed",
  "private": true,
  "license": "MIT",
  "devDependencies": {
    "karma": "~0.10",
    "protractor": "~0.20.1",
    "http-server": "^0.6.1",
    "bower": "^1.3.1",
    "shelljs": "^0.2.6"
  },
  "scripts": {
    "postinstall": "bower install",
    "prestart": "npm install",
    "start": "http-server -a localhost -p 8000",
    "pretest": "npm install",
    "test": "karma start karma.conf.js",
    "test-single-run": "karma start karma.conf.js  --single-run",
    "preupdate-webdriver": "npm install",
    "update-webdriver": "webdriver-manager update",
    "preprotractor": "npm run update-webdriver",
    "protractor": "protractor e2e-tests/protractor-conf.js",
    "update-index-async": "node -e \"require('shelljs/global'); sed('-i', /\\/\\/@@NG_LOADER_START@@[\\s\\S]*\\/\\/@@NG_LOADER_END@@/, '//@@NG_LOADER_START@@\\n' + cat('app/bower_components/angular-loader/angular-loader.min.js') + '\\n//@@NG_LOADER_END@@', 'app/index-async.html');\""
  }
}

但是我一直收到来自NPM的错误消息，其中说它＆＃34;未能解析json＆＃34;那个＆＃34; package.json必须是实际的JSON，而不仅仅是Javascript＆＃34; （错误代码EJSONPARSE）但jsonlint.com说它是一种有效的JSON格式。到底是怎么回事？以及如何才能真正成功地运行＆＃34; npm install＆＃34;从命令行。

$ npm install semver
$ node
> var semver = require('semver');
> semver.valid("~0.10"); // returns null
null

根据这个：https://docs.npmjs.com/files/package.json，您的所有版本号都应符合node-semver。

Git允许数字版本号。而npm没有。所以在你的情况下，依赖版本号需要采用package.json中的major.minor.patch格式。

npm说它不是json有效但是jsonlint.com说这是有效的
