NodeJS npm更新不执行任何操作

当我在package.json所在的应用程序文件夹中执行以下代码时：
npm update或npm update --save-dev，它不会执行任何操作。
但是当我做npm outdated的时候，它显示了很多过时的软件包。
那么，如何更新所有软件包呢？

OS: Win 10 x64
nodejs: 6.2.2
npm:3.10.7

package.json

{
  "name": "tgb-frontend",
  "version": "0.0.0",
  "license": "MIT",
  "angular-cli": {},
  "scripts": {
    "start": "ng serve",
    "lint": "tslint \"src/**/*.ts\"",
    "test": "ng test",
    "pree2e": "webdriver-manager update",
    "e2e": "protractor"
  },
  "private": true,
  "dependencies": {
    "@angular/common": "2.0.0",
    "@angular/compiler": "2.0.0",
    "@angular/core": "2.0.0",
    "@angular/forms": "2.0.0",
    "@angular/http": "2.0.0",
    "@angular/platform-browser": "2.0.0",
    "@angular/platform-browser-dynamic": "2.0.0",
    "@angular/router": "3.0.0",
    "core-js": "^2.4.1",
    "rxjs": "5.0.0-beta.12",
    "ts-helpers": "^1.1.1",
    "zone.js": "^0.6.23"
  },
  "devDependencies": {
    "@types/jasmine": "^2.2.30",
    "angular-cli": "1.0.0-beta.14",
    "codelyzer": "~0.0.26",
    "jasmine-core": "2.4.1",
    "jasmine-spec-reporter": "2.5.0",
    "karma": "1.2.0",
    "karma-chrome-launcher": "^2.0.0",
    "karma-cli": "^1.0.1",
    "karma-jasmine": "^1.0.2",
    "karma-remap-istanbul": "^0.2.1",
    "protractor": "4.0.5",
    "ts-node": "1.2.1",
    "tslint": "3.13.0",
    "typescript": "2.0.2"
  }
}

运行npm update --dd会产生以下提取输出：

npm update --dd输出在最后说明了原因：
...not updating @angular/common because it's currently at the maximum version that matches its specified semver range
看看这个特定的包，angular/common。你把它设置为2.0.0，这意味着npm总是会获取那个特定的版本。如果你想更新这个包，你需要使用一个semver范围。你可以在这里查看一个完整的semver范围列表，但是最常用的可能是~和^。
~意味着补丁版本将更新。因此，如果您有版本~1.2.1，它将更新到任何1.2.x，但永远不会更新到1.3.0。
^更新了次要版本，因此如果您有^1.2.1，它将更新到任何1.x.x发行版，但永远不会更新到2.0.0。

若要更新，请执行以下步骤：
1.运行npm outdated将允许您检查所有需要更新的软件包。列表将显示每个软件包的当前、想要的和最新版本。
1.接下来，运行npm update，它会将所有软件包更新到package.json中定义的最新 * 可能 * 版本。例如，如果package.json中的某个软件包的版本为**^2.3.1**，则此软件包将不会更新到2.x.x之后的版本。如果包的版本为**~5.3.2**，则不会更新到5.3.x之后。（要了解语义版本控制，请参阅read this）
1.但是，如果您想更新到最新版本，而package.json中的软件包版本阻止您按照上面步骤2中的描述进行更新，该怎么办呢？
a）您可以手动更新package.json中的软件包版本，方法是将软件包的版本更改为您希望的最新值。虽然这样做可能有效，但非常繁琐且容易出错。所以我不推荐这样做。
B）您可以自动更新package.json中的软件包版本。为此，您需要使用以下命令安装npm-check-updates软件包（我通常全局安装此软件包）：npm i -g npm-check-updates。完成此操作后，您必须运行ncu -u。这只会将package.json中的软件包版本更新为最新版本。可能会要求您运行npm install以安装可用的最新版本。我建议使用此方法。
1.现在，在package.json中更新软件包的版本后，运行npm update，您的软件包将被更新到最新版本。

如果npm [-g] outdated显示过期的软件包 * 超出 * 永久范围（例如，重大更新），则update命令 * 不能 * 用于更新这些软件包。
要安装最新版本，请使用

npm install [-g] <package>

当我刚接触Node.js的时候，我不知道下面的内容。如果它对你有帮助的话，我会和你分享。

  • npm版本：*
npm --version
  • 请注意，以下内容也会检查npm版本：*
npm --version <packagename> // package name argument is simply ignored
  • 软件包版本：*
npm list // at local directory to check local package versions
npm list -g // to check global package versions

还有一件事需要检查，它可能会影响你安装软件包的方式，并最终导致这个问题是你的.npmrc文件。检查它是否有这样的行：

save-exact=true

如果有，则移除它或将其设为false。当设为true时，会有下列行为：
使用--save、--save-dev或--save-optional保存到package.json的依赖项将被配置为精确的版本，而不是使用npm的默认semver范围操作符。
.npmrc和精确保存

使用bash上的一个liner将所有过时的软件包更新到最新版本

npm outdated | cut -d" " -f1 | tail -n +2 | sed 's/$/@latest/' | xargs npm i

如果你使用的是^或~，或者是你的前几个版本，那么你可以使用npm update <package-name>来cannot获得那个包的下一个主要版本。你可以使用npm outdated来检查你的过时包，并为每个包运行npm install <package-name>@latest，上面的一个程序将为你完成所有这些工作

您可以强制更新所有包**，即使它破坏了使用现有包的语义版本控制**。

  • 在重要项目中小心使用，在生产中绝对避免使用。*

我发现这个快捷方式对个人项目很有用。
此软件包将更新package.json中的所有依赖版本，并使用以下install命令安装它们。
npx npm-check-updates -u && npm i
