【中文标题】在具有 Nativescript 和 Angular Schematics 的共享代码中找不到模块【英文标题】:Modules not found in shared code with Nativescript and Angular Schematics 【发布时间】:2019-03-25 17:46:53 【问题描述】:

我正在使用带有 Nativescript Schematics 的 Angular。我已经安装了 nativescript-ui-sidedrawer。当我跑步时

tns run ios --bundle

本机版本已编译并部署到设备但当我运行时

ng serve

网页版失败并出现多个错误,都非常相似。第一个是

ERROR in ./node_modules/tns-core-modules/ui/builder/component-builder/component-builder.js
Module not found: Error: Can't resolve '../../../platform' in '/Users/markdev/Documents/Code/mydrawer/node_modules/tns-core-modules/ui/builder/component-builder'

所有错误都与路径有关。

如果我浏览到上面给出的错误并编辑“component-builder.js”,并将路径更改为

~/node_modules/tns-core-modules/platform

来自

../../../platform

然后在运行“ng serve”时,该特定错误不会显示在输出的错误列表中。

但是...当我运行时

tns run ios --bundle

我明白了

ERROR in ../node_modules/tns-core-modules/ui/builder/component-builder/component-builder.js
Module not found: Error: Can't resolve '/Users/markdev/Documents/Code/mydrawer/src/node_modules/tns-core-modules/platform' in '/Users/markdev/Documents/Code/mydrawer/node_modules/tns-core-modules/ui/builder/component-builder'
 @ ../node_modules/tns-core-modules/ui/builder/component-builder/component-builder.js 7:15-66
 @ ../node_modules/tns-core-modules/ui/builder/builder.js
 @ ../node_modules/tns-core-modules/ui/repeater/repeater.js
 @ ../node_modules/tns-core-modules/bundle-entry-points.js
 @ ./main.ns.ts

如果我在设备上打开应用程序,我会得到

*** Terminating app due to uncaught exception 'NativeScript encountered a fatal error: Error: Cannot find module '~/node_modules/tns-core-modules/platform'

谁能解释一下为什么不同的设备需要不同的路径?

【问题讨论】:

即使在全新的模板项目中也会发生这种情况,还是仅在添加侧抽屉插件时才会发生这种情况?如果是在插件之后,您是否介意分享我们可以看到问题的仓库。 嗨,@Manoj。只有在安装 Sidedrawer 后。重现步骤.. 1. 运行 ng new --collection=@nativescript/schematics --shared 2. cd 3. tns plugin add nativescript-ui-sidedrawer 4. 配置 Sidedrawer - docs.telerik.com/devtools/nativescript-ui/Controls/Angular/… .. .... ....我将 SideDrawerModule 添加到 app.module.tns.ts 中,将抽屉添加到 app.component.tns.html 中,并将代码添加到 app.component.ts 中,即当它破裂时。有一系列问题需要克服,它找不到 Observable、ActionItem。然后 ./node_modules/tns-core-modules/profiling/profiling.js 中的警告找不到 /package.json。然后有 49 个错误,包括我在最初的帖子中提到的那个。这是我的代码github.com/markbell2410/mydrawer 我可以知道你在 app.component.ts 中到底有什么吗? 当然。 github.com/markbell2410/mydrawer/blob/master/src/app/… 【参考方案1】:

查看您的应用组件,这是一个有效错误。 Page、ActionItem、RadSideDrawerComponent 等仅适用于您的移动应用程序。因此,当您在为 web 编译时使用导入 tns 特定组件的通用应用程序组件时,它应该会抛出错误。

如果您有通用代码,请将其移至基类并继承 Web 和移动平台特定的组件。如果没有通用代码,则只需创建应用组件的 tns 版本,web 应该有它自己的版本。

在此期间,您可能需要更新您的导入语句。从节点模块导入包时,您不必使用相对路径。

【讨论】:

谢谢,Manoj。我期待一些 TS/NG 魔术,但这会很好。再次感谢
