Ionic cordova build iOS 没有创建 build 文件夹并得到 sass gulp 错误答案

【问题标题】：Ionic cordova build iOS not creating build folder and getting sass gulp errorIonic cordova build iOS 没有创建 build 文件夹并得到 sass gulp 错误

【问题描述】：

我刚刚将我的 MacOS 环境从 Ionic CLI 1.7.14 升级到 v5.2.6。这也需要我将 NodeJS 升级到 v10.16.3。我有几个问题，但其中一个是当我构建应用程序时，platforms/ios/build 目录没有被创建。

但是，我可以将应用程序直接从 Xcode 部署到我的测试手机 - 但它的所有内容都不稳定、缺少图像、后端服务器 api 调用无法正常工作、应用程序中指向其他应用程序页面的 URL 链接无法正常工作。即使从 Xcode 部署后仍然没有构建目录。同样，Safari 网络检查器会打开一个空白窗口...没有元素，控制台信息，什么都没有。

我的构建中似乎没有任何错误。下面是 --verbose 输出：

=======================

凭直觉，我删除了自动安装的Cordova-plugin-ionic-webview（在构建新应用程序时，这似乎是 Ionic CLI 的标准配置）并返回使用我以前的 web view-plus（是的，很旧，但它在 CLI 大升级之前我一直在使用的东西——它工作得很好）。我尝试从控制台再次构建，它没有任何错误，但又没有 platform/ios/build 文件夹 - 但是，我可以从 Xcode 干净地部署我的应用程序 - 所有不稳定的东西都消失了 - 我的应用程序正在运行并且我可以管理应用程序再次来自 Safari 网络检查器。关于 ionic-web 视图的某些东西一定会导致所有的问题 - 但仍然不能解释构建问题。

标签： ios cordova ionic-framework gulp-sass

【解决方案1】：

这通常是同时安装了多个版本的gulp造成的。

尝试同时删除package-lock.json 文件和node_modules 文件夹。然后使用npm i 重新安装依赖项并尝试再次构建您的应用程序。

【讨论】：

我完全重建了我的项目，现在 gulpfile.js euror 已经消失了。 ionic cordova build ios 构建干净，但仍然没有 /build 文件夹。

【解决方案2】：

我以前也遇到过类似的情况。这是对我有用的解决方案：

移除IOS平台ionic cordova platform remove ios
再次添加平台ionic cordova platform add ios
使用 XCode 配置签名设置
同样在 XCode 中的 File -> Workspace settings 中启用“Legacy build system”
再次尝试构建

【讨论】：

【解决方案3】：

我重新安装了我的项目并调整了我的 gulp 版本，但问题仍然存在。

原来Preparing Firebase on iOS 是线索。它是构建过早退出之前的最后一条消息，但退出时没有错误、问题、警告或任何内容。

Cordova-plugin-firebasex @6.0.7 有一个问题会影响构建。我已降级到 v6.0.6，现在一切正常。
