如何自动安装npm peer dependencies？

Question

例如,当我安装Angular2时:

npm install --save angular2
temp@1.0.0 /Users/doug/Projects/dougludlow/temp
??? angular2@2.0.0-beta.3 
??? UNMET PEER DEPENDENCY es6-promise@^3.0.2
??? UNMET PEER DEPENDENCY es6-shim@^0.33.3
??? UNMET PEER DEPENDENCY reflect-metadata@0.1.2
??? UNMET PEER DEPENDENCY rxjs@5.0.0-beta.0
??? UNMET PEER DEPENDENCY zone.js@0.5.11

npm WARN angular2@2.0.0-beta.3 requires a peer of es6-promise@^3.0.2 but none was installed.
npm WARN angular2@2.0.0-beta.3 requires a peer of es6-shim@^0.33.3 but none was installed.
npm WARN angular2@2.0.0-beta.3 requires a peer of reflect-metadata@0.1.2 but none was installed.
npm WARN angular2@2.0.0-beta.3 requires a peer of rxjs@5.0.0-beta.0 but none was installed.
npm WARN angular2@2.0.0-beta.3 requires a peer of zone.js@0.5.11 but none was installed.

是否有一个魔法标志,我可以传递给npm,也将安装对等依赖项？我找不到一个...手动复制和粘贴对等依赖项并确保我有正确的版本是很繁琐的.

换句话说,我宁愿不必这样做:

npm install --save angular2@2.0.0-beta.3 es6-promise@^3.0.2 es6-shim@^0.33.3 reflect-metadata@0.1.2 rxjs@5.0.0-beta.0 zone.js@0.5.11

有什么更好的方法？

Answer 1

使用npm 3显式删除了对等依赖项的自动安装,因为它会导致比尝试解决的问题更多的问题.你可以在这里阅读它,例如:

• https://blog.npmjs.org/post/110924823920/npm-weekly-5
• https://github.com/npm/npm/releases/tag/v3.0.0

所以不,由于给出的原因,您无法使用npm 3向上自动安装它们.

Answer 2

我通过重写package.json解决了它的确切值警告是关于:

npm WARN angular2@2.0.0-beta.3 requires a peer of es6-shim@^0.33.3 but none was installed.

package.json:"es6-shim":"^ 0.33.3",

npm WARN angular2@2.0.0-beta.3 requires a peer of reflect-metadata@0.1.2

package.json:"reflect-metadata":"0.1.2",

Delete node_modules directory

npm install

Answer 3

作弊代码在这种情况下有用,还有一些......

├──UNMETPEER DEPENDENCY @ angular/common @ 4.0.2

├──UNMETPEER DEPENDENCY @ angular/compiler @ 4.0.2

├──UNMETPEER DEPENDENCY @ angular/compiler-cli @ 4.0.2

├──UNMETPEER DEPENDENCY @ angular/core @ 4.0.2

├──UNMETPEER DEPENDENCY @ angular/forms @ 4.0.2

├──UNMETPEER DEPENDENCY @ angular/http @ 4.0.2

├──UNMETPEER DEPENDENCY @ angular/platform-b​​rowser @ 4.0.2

├──UNMETPEER DEPENDENCY @ angular/platform-b​​rowser-dynamic @ 4.0.2>

1. 将错误复制并粘贴到代码编辑器中.
2. 使用光标突出显示不需要的部分.在这种情况下'├──UNMETPEER DEPENDENCY'
3. 多次按命令+ d.
4. 按删除两次.(如果您不小心突出显示'├──UNMETPEER DEPENDENCY',请按空格键.)
5. 按一下.添加'npm install'
6. 按下一次.添加'--save
7. 将您的东西复制回cli并运行

npm install @ angular/common @ 4.0.2 @ angular/compiler @ 4.0.2 @ angular/compiler-cli @ 4.0.2 @ angular/core @ 4.0.2 @ angular/forms @ 4.0.2 @ angular/http @ 4.0 .2 @ angular/platform-b​​rowser @ 4.0.2 @ angular/platform-b​​rowser-dynamic @ 4.0.2 --save

Answer 4

该项目npm-install-peers将检测同行并安装它们.

因为v1.0.1它不支持package.json自动写回,这基本上解决了我们的需求.

Answer 5

我在开发具有peerDependencies. 我必须确保 anypeerDependencies也被列为devDependencies. 该项目不会自动使用全局安装的包。

Answer 6

我遇到了同样的问题，幸运的是我找到了另一种方法来安装对等依赖项以及安装命令。

步骤1：$ npm i npm-install-peers -D

为了更清楚地了解该插件：https ://www.npmjs.com/package/npm-install-peers

第2步：更新package.json魔法脚本

  ....
   "scripts": {
    ...
    "postinstall": "npm-install-peers"
  },
  ....

第 3 步：只需点击安装命令即可安装所有插件

$ npm install
