Question

我在运行ng build命令时遇到以下错误。删除了node_modules文件夹和npm installe，提供了以下警告

npm WARN angular2-cool-storage@3.1.2 requires a peer of @angular/core@5.0.0 but none was installed.
npm WARN angular2-cool-storage@3.1.2 requires a peer of @angular/common@^5.0.0 but none was installed.

对于ng build下面的id deetail错误：

模块中元数据版本不匹配的错误 /node_modules/angular2-cool-storage/index.d.ts，发现版本4，预期3，在/src/app/app.module.ts中解析符号AppModule 解析/src/app/app.module.ts中的符号AppModule

Package.json是

之前我使用 angular2-cool-storage ，现在安装并使用 ng2-cookies ng build之后失败了。请给我一个解决方案。

Answer 1

似乎存在软件包兼容性问题，您应该按照此guide将软件包升级到angular 5以制作软件包的兼容版本，我已经尝试过并且运行良好

npm install @ angular / animations @ ^ 5.0.0 @ angular / common @ ^ 5.0.0 @ angular / compiler @ ^ 5.0.0 @ angular / compiler-cli @ ^ 5.0.0 @ angular / core @ ^ 5.0.0 @ angular / forms @ ^ 5.0.0 @ angular / http @ ^ 5.0.0 @角/平台的浏览器@ ^ 5.0.0 @角/平台的浏览器的动态@ ^ 5.0.0 @ angular / platform-server @ ^ 5.0.0 @ angular / router @ ^ 5.0.0 typescript@2.4.2 rxjs@^5.5.2

Answer 2

消息似乎很清楚：你需要一个角度核心和普通版本至少5.0.0。

您的包文件显示4.4.3版本。

尝试更新您的软件包或降级您的依赖项，然后重试！

Answer 3

为了保持包的一致性，我更新了我的package.json文件。从包名中删除了插入符号（^），因此它现在不更新包标题。它强制npm仅坚持使用指定的版本。

"angular2-cool-storage": "^3.1.0" => "angular2-cool-storage": "3.1.0"

检查先前与相同角度版本兼容的软件包版本，如果软件包的自动升级发生Metadata version mismatch，则在package.json中指定不带^的条目。

模块中的错误元数据版本不匹配/node_modules/angular2-cool-storage/index.d.ts，找到版本4，预期3，
