npm 没有安装 Angular Bootstrap 我需要的版本

Question

这是我的package.json。

{
"name": "MyProject",
"private": true,
"version": "0.0.0",
"scripts": {
"test": "karma start ClientApp/test/karma.conf.js"
},
"devDependencies": {

"@angular/platform-browser-dynamic": "5.0.2",
"@angular/platform-server": "5.0.2",
"@angular/router": "5.0.2",
"@ngtools/webpack": "1.5.0",
"@types/chai": "4.0.1",
"@types/jasmine": "2.5.53",
"@types/webpack-env": "1.13.0",
"angular2-router-loader": "0.3.5",

"event-source-polyfill": "0.0.9",
"expose-loader": "0.7.3",
"extract-text-webpack-plugin": "2.1.2",
"file-loader": "0.11.2",
"html-loader": "0.4.5",
"isomorphic-fetch": "2.2.1",
"jasmine-core": "2.6.4",
"jquery": "3.2.1",
"json-loader": "0.5.4",
"karma": "1.7.0",
"karma-chai": "0.1.0",
"karma-chrome-launcher": "2.2.0",
"karma-cli": "1.0.1",
"karma-jasmine": "1.1.0",
"karma-webpack": "2.0.3",
"preboot": "4.5.2",
"raw-loader": "0.5.1",
"reflect-metadata": "0.1.10",
"rxjs": "5.4.2",
"style-loader": "0.18.2",
"to-string-loader": "1.1.5",
"typescript": "2.4.1",
"url-loader": "0.5.9",
"webpack": "2.5.1",
"webpack-cli": "^2.0.14",
"webpack-hot-middleware": "2.18.2",
"webpack-merge": "4.1.0",
"zone.js": "0.8.12"
},
"dependencies": {
"@ng-bootstrap/ng-bootstrap": "^1.1.2"
}
}

这大部分是由 ASP.Net 核心 2 模板使用 "dotnet new angular" 命令生成的。我只需要添加 ng-bootstrap 并将版本更新为推荐的版本（Angular 至少应为 5.0.2，Bootstrap 应至少为 4.0.0。）

但是，当我这样做时 "npm install"，我得到了一个较低的版本。

├── @angular/animations@4.2.5
├── @angular/common@4.2.5
├── @angular/compiler@4.2.5
├─┬ @angular/compiler-cli@4.2.5
│ └── minimist@1.2.0
├── @angular/core@4.2.5
├── @angular/forms@4.2.5
├── @angular/http@4.2.5
├── @angular/platform-browser@4.2.5
├── @angular/platform-browser-dynamic@4.2.5
├── @angular/platform-server@4.2.5
├── @angular/router@4.2.5
├── @angular/tsc-wrapped@4.2.5
...

因此，运行我的应用程序出现以下错误。

NodeInvocationException: Can't resolve all parameters for
NgbModalStack: ([object Object], [object Object], [object Object], ?).

我确定错误是由错误的版本引起的，如 this issue 所述。

Answer 1

第 1 步：将 npm install ng-bootstrap 添加到您想要的版本。

第 2 步：删除 package-lock.json 和节点模块文件夹。

第 3 步：检查 package.json 文件中是否列出了任何其他不需要的 bootstrap。如果是这样，请将其删除并在文件中保留您想要的 ng-bootstrap 版本。

第 4 步：重新安装 npm 模块 npm i.
