npm警告…需要与……但是没有安装。您必须自己安装对等依赖项

我试图运行一个从github下载的项目。不幸的是，在npm install期间显示了以下警告。我尝试基于问题更改版本。但是，我遇到了一个问题，因为一些包需要其他包的多个版本。考虑这两行:

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，安装一些包会导致依赖项列表大幅增加。

有人有办法吗?

你只需要依赖angular的一个主要版本，所以要根据angular 2更新所有模块。x:

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

"A需要B的对等体，但没有安装"。把它当做“A” 需要B的一个对等点，但是那个对等点没有安装，我们 没有告诉你你需要B的哪些同事。" < / p >

npm 3明确地删除了对等依赖的自动安装。

NPM Blog

v3版本说明书 . > . > v3版本说明书

所以在npm 3及以上版本中，你不能自动安装对等依赖项。

更新的解决方案:

对每个对等依赖项使用以下命令来安装并删除错误

npm install --save-dev xxxxx

弃用的解决方案:

  1. 你可以使用npm-install-peers来查找和安装所需的对等依赖项。

    npm install -g npm-install-peers

    npm-install-peers < / p >

  2. 如果在更新任何包的版本后出现此错误，则删除node_modules目录并通过npm install或npm cache clean和npm install重新安装包。

小开

我有一个类似的问题，并解决后运行这些指令!

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

使用npm-install-peers不能工作，也不能删除node_modules并重新构建。逃跑的答案

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

对于每一个，XXXXX都是指同行警告中的确切文本。我只有四个警告，如果我像问题中那样有十几个或更多警告，那么编写脚本命令可能是个好主意。

总边缘情况在这里:我有这个问题安装Arch AUR PKGBUILD文件手动。在我的情况下，我需要删除“pkg”，“src”和“node_modules”文件夹，然后它构建良好，没有这个npm错误。

小开

在安装角材质CDK时也遇到了同样的问题:

npm install --save @angular/material @angular/cdk @angular/animations

像下面这样添加-dev对我有用:

npm install --save-dev @angular/material @angular/cdk @angular/animations
小开

对于表单中的每一个错误:

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

你应该:

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

请注意:如果{other thing}有空格，就需要引号，就像下面的例子:

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"
小开 
npm install -g npm-install-peers

它将添加所有缺失的对等体并删除所有错误

在我的案例中，以下命令对我很有效:

sudo npm cache clean --force
sudo npm install -g npm




sudo apt install libssl1.0-dev
sudo apt install nodejs-dev
sudo apt install node-gyp
sudo apt install npm

之后，如果你遇到“无法找到模块'bcrypt'”，那么你可以用下面的命令来解决这个问题:

npm install node-gyp -g
npm install bcrypt -g
npm install bcrypt --save

希望这对你也有用。

npm i -D @angular/material @angular/cdk @angular/animations

我在react-firebase-file-uploader上也遇到了同样的问题。

AWS CDK也有同样的问题，但对我来说，在npm install之前rm -rf node_modules是有帮助的。

还要确保所有aws-cdk组件的版本相同。

小开

我不知道是否有人尝试过这个新包:

npm install -g install-peerdeps

这是npm install -g npm-install-peers的替代

npm i [package-name] --force

——使用武力。

因为npm7发布了，你现在可以自动安装对等依赖项了。 他们制定了一种算法，以确保在node_modules树中对等依赖项的位置或上面找到一个有效匹配的对等依赖项。如果是这样，那么他们正确地添加了对等依赖项。 你只需要安装NPM 7

npm i -g npm@7
