npm WARN ...需要一个对等...但没有安装.您必须自己安装对等依赖项

我试图运行从github下载的项目.不幸的是,在npm install以下警告显示.我试图根据这个问题更改版本.但是,我遇到了问题,因为有些软件包需要多个版本的其他软件包.考虑以下两行:

npm WARN @angular/cdk@2.0.0-beta.10 requires a peer of @angular/core@^4.3.0 but none is installed. You must install peer dependencies yourself.

npm WARN @angular/forms@4.3.6 requires a peer of @angular/core@4.3.6 but none is installed. You must install peer dependencies yourself.

因此,安装某些软件包会导致依赖项列表大幅增加.

有没有人有办法解决吗？

"A需要B的同行,但没有安装".将其视为"A需要B的同伴中的一个,但未安装同伴,我们不会告诉您需要哪个B的同伴."

使用npm 3显式删除了对等依赖项的自动安装.

NPM博客

v3的发行说明

因此,您无法使用npm 3及更高版本自动安装对等依赖项.

解

您可以使用npm-install-peers查找和安装所需的对等依赖项.

npm install -g npm-install-peers

npm-install-peers
如果要更新任何软件包的版本之后收到此错误然后删除node_modules目录,并重新安装包npm install或npm cache clean和npm install.

我正在调试与OP相同的问题,npm-install-peers仅返回`此包似乎没有任何peerDependencies` (14认同)
“...安装它并删除错误”似乎是不正确的英语。还不清楚“xxxxx”与“A”和“B”有何关系。 (8认同)
对于未来的读者来说,这不是正确的解决方案,因为`npm-install-peers`只会安装**直接**对等依赖项,而不是依赖项的对等依赖项.查看他们链接的github页面. (3认同)
`--save-dev` 有什么作用？ (3认同)

Answer 2

小智 26

使用npm-install-peers的接受答案不起作用,也不删除node_modules和重建.跑步的答案

npm install --save-dev @xxxxx/xxxxx@latest

Run Code Online (Sandbox Code Playgroud)

对于每一个,xxxxx引用同伴警告中的确切文本,工作.我只有四个警告,如果我在问题中有十几个或更多,那么编写命令可能是一个好主意.

`package@latest` 是进入兔子洞的方法 (12认同)
请在“ xxxxx引用对等方警告中的确切文本”中更明确地说明`npm WARN ABC要求对等方为XYZ @ VER，但未安装任何对等方。您必须自己安装对等依赖项。`，我们应该使用ABC，XYZ还是警告的其他部分？ (6认同)
保存到开发依赖项意味着它仅在开发期间使用。Angular core 绝对不是开发依赖项，而是生产依赖项。 (5认同)
为什么`--save-dev`？那不会在package.json中将peerDependency添加为devDependency吗？ (3认同)
@Serge我从您的示例中使用了等效的XYZ @ VER，它对我有用 (3认同)
使用@latest 对我来说是个坏主意。我最终得到了更多版本不匹配的项目。我最终使用了请求的版本。如果需要两个不同版本的包，我会检查两端是否可以使用不同的版本来解决不匹配问题。 (3认同)
为什么不保存呢？如果开发依赖项缺少所需的包，则应将其添加并保存到 devDependencies 中，以确保开发人员/CI 的下一次安装将具有相同的可用节点模块。 (2认同)

Answer 3

小智 10

npm install -g npm-install-peers

Run Code Online (Sandbox Code Playgroud)

它将添加所有丢失的对等点并删除所有错误

使用此命令只会从您的项目安装 package.json 中的直接对等依赖项。您仍然会收到警告，指出您的所有项目依赖项都缺少对等依赖项。 (6认同)
对于所需的解决方案，这似乎已被弃用。不再工作了 (5认同)

Answer 4

小智 10

自从 npm7 发布以来，您现在可以自动安装对等依赖项。他们制定了一种算法来确保在 node_modules 树中的对等依赖项位置或上方找到有效匹配的对等依赖项。如果是这种情况，那么他们会正确添加对等依赖项。你只需要安装 npm 7

npm i -g npm@7

对于形式的每个错误：

npm WARN {something} requires a peer of {other thing} but none is installed. You must install peer dependencies yourself.

Run Code Online (Sandbox Code Playgroud)

你应该：

$ npm install --save-dev "{other thing}"

注意：如果{other thing}包含空格，则需要使用引号，例如以下示例：

npm WARN rollup-plugin-uglify@6.0.3 requires a peer of rollup@>=0.66.0 <2 but none was installed.

解决：

$ npm install --save-dev "rollup@>=0.66.0 <2"

围绕这一点似乎仍然存在很多混乱。如果 NPM 输出建议的命令来安装缺少的对等依赖项，那将会非常有帮助。 (27认同)
顺便说一句，“--save-dev”有什么作用？ (10认同)
`--save-dev` 将依赖项作为*开发依赖项*保存到您的 `package.json` - [npm doc](https://docs.npmjs.com/specifying-dependency-and-devdependency-in-a -package-json-file#从命令行添加依赖项到packagejson-file) (7认同)
这有效但让我陷入了困境。当我安装 @angular/core@12.2.5 时，我会得到一些软件包的“requires @angular/core@12.0.0”。如果我安装 @angular/core@12.0.0 ，我会得到“需要@angular/core@12.2.5”，这是合理的。某些依赖链中有很多怪癖，我可以很高兴地将所有这些都扔掉 (6认同)
虽然这可以说是与其他答案相同的答案，但它是唯一一个清楚地解释了要替换为其他答案仅列出为“xxxxx”的区域的内容的答案。谢谢你的澄清。 (4认同)

我对react-firebase-file-uploader 也有同样的问题。

npm i {something} --legacy-peer-deps  #worked fine for me

这应该是正确的答案，尽管正斜杠可能应该是散列注释，除非*当然*您通过 IRC 访问它。```npm i --legacy-peer-deps``` 解决了我遇到的同样问题。 (2认同)

运行这些说明后，我遇到了类似的问题并解决了！

npm install npm -g
npm install --save-dev @angular/cli@latest
npm install
npm start

我怀疑“npm install npm -g”对每个人来说都不是一个好主意，因为这会更新“npm”，对吗？ (5认同)
正确的。说到最佳实践，每个节点开发人员最终都会有一天使用“nvm”。它可以根据您打算使用的“node”版本轻松地使“npm”版本保持最新。 (2认同)

您只需要依赖 Angular 的一个主要版本，因此根据 Angular 2.x 更新所有模块：

将 @angular/flex-layout 更新为 ^2.0.0-beta.9
将@angular/material更新为^2.0.0-beta.12
将 angularfire2 更新为 ^4.0.0-rc.2
将 zone.js 更新为 ^0.8.18
将 webpack 更新为 ^3.8.1
添加@angular/cdk@2.0.0-beta.12（@angular/material 必需）
将 angular2-google-maps 替换为 @agm/core@1.0.0-beta.1 （新名称）

您能阐述一下并给出一个通用的解决方案吗？我有类似的问题，并且不想按照上面评论中的建议“忽略警告”。需要什么配置才能不显示此类警告？注意：对于我的项目来说，“npm WARN react-test-renderer@16.1.1需要react@^16.0.0的同级，但没有安装...”，是的，我确实安装了所需的同级。这是我的项目的问题还是react-test-renderer项目的问题？或者我是否需要找到所有同行并以某种方式使他们的版本保持一致？ (7认同)
