我最近将离子更新到版本3.9.2但运行时发生错误＆＃34;离子cordova运行android --device＆＃34;或者当我使用Ionic DevApp时。
当我在我的智能手机上使用Android 7.0执行命令时，所有功能都完美无缺，但在使用android 4.4.4在我的平板电脑上运行时出现错误
跑步＆＃34;离子医生检查＆＃34;没有发现问题。
错误是＆＃34;意外的令牌＆lt;＆＃34;，没有其他细节。
这是我的package.json

如果我在控制台中检查我的平板电脑设备，我看到该错误引用了main.js中的一行这是行

我没有记错。在手机中一切都还可以，平板电脑没有。这是一个离子错误还是我的错误？
谢谢
更新13/11/2017 新的调查：问题是设备与Android版本＆lt; = 4.4.4智能手机和平板电脑。 但Ionic 3本身不支持android 4.4 +？
更新13/11/2017＃2 问题解决了。我已经安装了crosswalk插件而不是所有的工作
答案 0 :(得分：0)
当我在我的智能手机Huawaei上使用android 7.0执行命令时 一切都很完美，但是在我的平板电脑上运行时我会收到错误 用android 4.4.4
错误是“意外的令牌＆lt;”，没有其他细节。
我刚刚遇到了一个非常类似的问题，因为在一个特定的设备上（恰好是Android 4.4.4），浏览器webview太老了，无法理解编译的JavaScript。
这将导致可怕的“白屏死机”，并且调试会特别痛苦。
一个简单的解决方案就是使用人行横道：
ionic cordova plugin add cordova-plugin-crosswalk-webview
重建，问题应该消失。
虽然这会使你的APK膨胀，增加一些额外的25Mb，但我建议在支持相当旧的设备时总是使用人行横道。
即使它在没有这些功能的情况下也能正常工作，通常会有一些微妙的事情，比如动画输入等等，会导致用户体验不佳。
答案 1 :(得分：0)
android 7.0支持es6（es2015）和android 4.4.4可能没有 - 我有一个类似的问题，因为autocomplete错误导入了离子角度es2015中的一个类
我从' ionic-angular / es2015 '导入{Slides}而不是从' ionic-angular '导入{Slides};
答案 2 :(得分：0)
检查捆绑文件是否确实存在。 通常会发生此问题，因为浏览器找不到捆绑包JS文件。此“ <”令牌仅是404响应服务器的html开头标记。 应用程序希望读取JS而不是HTML
