How to install npm peer dependencies automatically?
提问by Douglas Ludlow
For example, when I install Angular2:
例如，当我安装 Angular2 时：
npm install --save angular2
[email protected] /Users/doug/Projects/dougludlow/temp
├── [email protected]
├── UNMET PEER DEPENDENCY es6-promise@^3.0.2
├── UNMET PEER DEPENDENCY es6-shim@^0.33.3
├── UNMET PEER DEPENDENCY [email protected]
├── UNMET PEER DEPENDENCY [email protected]
└── UNMET PEER DEPENDENCY [email protected]
npm WARN [email protected] requires a peer of es6-promise@^3.0.2 but none was installed.
npm WARN [email protected] requires a peer of es6-shim@^0.33.3 but none was installed.
npm WARN [email protected] requires a peer of [email protected] but none was installed.
npm WARN [email protected] requires a peer of [email protected] but none was installed.
npm WARN [email protected] requires a peer of [email protected] but none was installed.
Is there a magic flag that I can pass to npm that will install the peer dependencies as well? I haven't been able to find one... It's tedious to manually copy and paste the peer dependencies and make sure I have the correct versions.
是否有一个魔术标志可以传递给 npm 来安装对等依赖项？我一直找不到...手动复制和粘贴对等依赖项并确保我拥有正确的版本很乏味。
In other words, I'd rather not have to do:
换句话说，我宁愿不必这样做：
npm install --save [email protected] es6-promise@^3.0.2 es6-shim@^0.33.3 [email protected] [email protected] [email protected]
What is the better way?

The automatic install of peer dependencies was explicitly removed with npm 3, as it cause more problems than it tried to solve. You can read about it here for example:
npm 3 明确删除了对等依赖项的自动安装，因为它导致的问题比它试图解决的问题要多。例如，您可以在此处阅读有关它的信息：
So no, for the reasons given, you cannot install them automatically with npm 3 upwards.
所以不，由于给出的原因，您不能使用 npm 3 自动安装它们。

I solved it by rewriting package.json with the exact values warnings were about:
我通过使用警告的确切值重写 package.json 解决了它：
npm WARN [email protected] requires a peer of es6-shim@^0.33.3 but none was installed.
package.json: "es6-shim": "^0.33.3",
package.json: "es6-shim": "^0.33.3",
npm WARN [email protected] requires a peer of [email protected]
package.json: "reflect-metadata": "0.1.2",
package.json: "reflect-metadata": "0.1.2",
Delete node_modules directory
npm install

The project npm-install-peerswill detect peers and install them.
该项目npm-install-peers将检测对等点并安装它们。
As of v1.0.1it doesn't support writing back to the package.jsonautomatically, which would essentially solve our need here.
由于v1.0.1它不支持package.json自动回写，这基本上可以解决我们的需求。

I experienced these errors when I was developing an npm package that had peerDependencies. I had to ensure that any peerDependencieswere also listed as devDependencies. The project would not automatically use the globally installed packages.
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。
