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，

Question

我在运行ng build命令时遇到错误。删除node_modules文件夹并安装npm，给出以下警告

npm WARN [email protected] requires a peer of @angular/[email protected] but none was installed.
npm WARN [email protected] 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/node_modules/angular2-cool-storage/index.d.ts的元数据版本不匹配，找到版本4，预期3，解析/src/app/app.module.ts中的符号AppModule解析/ src /中的符号AppModule应用程序/ app.module.ts

Package.json是

之前我使用过angular2-cool-storage，现在安装和使用ng2-cookies之后，构建失败了。请建议我一个解决方案。

Answer 1

看来有一个软件包兼容性问题，你应该按照这个guide将软件包升级到angular 5来制作软件包的兼容版本，我已经尝试了它并且运行良好

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 @ angular / platform-b​​rowser @ ^ 5.0.0 @ angular / platform-b​​rowser-dynamic @ ^ 5.0.0 @ angular / platform-server @ ^ 5.0 .0 @ angular / router @ ^ 5.0.0 [email protected] rxjs@^5.5.2

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，然后再试一次！

为了一致性，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，并在package.json中指定那些没有^的条目，如果软件包的自动升级发生Metadata version mismatch。
