Npm 安装失败，节点 15（非 LTS）“@angular-devkit/build-angular”：“~0.1000.0”

Question

npm install fail with below dependency "@angular-devkit/build-angular": sample package.json

  {
  "name": "myApp",
  "version": "0.0.1",
  "devDependencies": {
    "@angular-devkit/build-angular": "~0.1000.0"
  }
}

I am using node V15.5.1 npm v7.3.0

I'm getting below errors:

npm ERR: Found. typescript@4.0.5 npm ERR. node_modules/typescript npm ERR. peer typescript@">=3.9 <4.1" from @angular/compiler-cli@10.2.4 npm ERR. node_modules/@angular/compiler-cli npm ERR. peer @angular/compiler-cli@">=10.0.0-next.0 < 11" from @angular-devkit/build-angular@0.1000.8 npm ERR!

not sure why node/npm is looking for typescript 4.0.5 instead of the version that can suit both the ranges. (peer typescript@">=3.9 <4.1" and peer typescript@">=3.9 < 3.10" ) is this working as expected.

i can able to run the npm install with --legacy-peer-deps flag.

is this a problem or its working as designed. why cant npm choose the version which suits both cases

Use LTS version of node, currently 14.15.4. Changing the version depends on your OS and package manager, but at least on MacOS and Homebrew it goes like this:

brew update
brew install node@14
brew link --overwrite node@14
