我看到了一些教程,命令是:
npm install --save
该--save选项意味着什么？
无法在Google上找到答案.
我想,当我运行此命令的版本降级到角CLI 4创建角4项目,而不是5角我CLI版本1.5.0
npm install -g angular-cli@1.4.9
我收到了错误
npm ERR! code ETARGET
npm ERR! notarget No matching version found for angular-cli@1.4.9
我将我的 Angular 项目升级到 7.1.4。升级后，在“@angular/cdk/stepper”中找不到“STEPPER_GLOBAL_OPTIONS”
这是我的 package.json
尝试从 node_modules 中删除所有包并运行 npm install
"dependencies": {
"@angular/animations": "^7.1.4",
"@angular/cdk": "^7.0.3",
"@angular/common": "^7.1.4",
"@angular/compiler": "^7.1.4",

"@angular/http": "^7.1.4",
"@angular/material": "^7.2.0",
"@angular/platform-browser": "^7.1.4",
"@angular/platform-browser-dynamic": "^7.1.4",

"popper.js": "^1.14.4",
"rxjs": "^6.3.3",
"rxjs-compat": "^6.3.3",
"zone.js": "^0.8.26"
},
我该如何解决这个问题？
