android - 未捕获的语法错误意外标记 main.js 选择器 : 'page-home' , 模板:- ionic3

Question

在 Android 6 Marshmallow 上，apk 构建时它工作正常 但在 Android Lollipop 中的“选择器:”代码行处出错

错误:

Uncaught SyntaxError: Unexpected token ILLEGAL in main.js warning : "The key "viewport-fit" is not recognized and ignored"

不知道怎么回事。

 `HomePage = __decorate([
        Object(__WEBPACK_IMPORTED_MODULE_0__angular_core__["m" /* Component */])({
            selector: 'page-home',template:/*ion-inline-start:"D:\2fb\src\pages\home\home.html"*/`\n  \n    \n      Facebook\n    \n  \n\n\n\n  \n    Facebook Login Example\n  \n\n  \n    Log In with Facebook\n  \n\n  \n    \n    \n      \n        {{ userProfile.displayName }}\n      \n      
\n        The UID for this new user is {{userProfile.uid}} and the email is {{userProfile.email}}\n      
\n    \n  \n`/*ion-inline-end:"D:\2fb\src\pages\home\home.html"*/
        }),
        __metadata("design:paramtypes", [__WEBPACK_IMPORTED_MODULE_2_ionic_angular__["d" /* NavController */], __WEBPACK_IMPORTED_MODULE_1__ionic_native_facebook__["a" /* Facebook */]])
    ], HomePage);`

当部署到 Android 4.4.4 时，我在使用 3.9.2 时遇到了类似的问题。可能的原因是用`(ASCII 96) 括起来的模板字符串不是常见的单引号(ASCII 39)。

我的丑陋修复是通过使用 after prepare 脚本将 ` 替换为 ' ，如下所示:

#!/usr/bin/env node

var fs = require('fs');
var path = require('path');

var rootdir = process.argv[2] + '/../';

function replace_string_in_file(filename, to_replace, replace_with) {
  var data = fs.readFileSync(filename, 'utf8');

  var result = data.replace(new RegExp(to_replace, "g"), replace_with);
  fs.writeFileSync(filename, result, 'utf8');
}

var target = "dev";
if (process.env.TARGET) {
  target = process.env.TARGET;
}

var replaceConfig = {
  "platforms/android/assets/www/build/main.js" : {
    "dev": {
      "/`": "/'",
      "`/": "'/"
    }
  }
};
for (var filename in replaceConfig) {
  var fullFilename = path.join(rootdir, filename);
  if (fs.existsSync(fullFilename)) {
    var replaceTexts = replaceConfig[filename];
    for (var key in replaceTexts[target]) {
      console.log(target + " replacing in file: " + fullFilename + " " + key + " as " + replaceTexts[target][key]);
      replace_string_in_file(fullFilename, key, replaceTexts[target][key]);
    }
  } else {
    console.log("missing: " + fullFilename);
  }
}

它解决了我的问题。希望这会有所帮助。
