当id将android studio更新到3.6 android gradle工具到3.6.0时，出现问题。当我生成sign apk时，出现异常？是这样的

据我从教程中了解到， pnpm.registry.npmjs.org在 下创建符号链接和其他条目点node_modules。我的项目已经启动typescript，我需要@types输入node_modules. 但这@types也有在node_modules/.registry.npmjs.org/@types。所以我收到如下错误：

/node_modules/.registry.npmjs.org/@types/jquery/3.3.5/node_modules/@types/jquery/index.d.ts(32,14): error TS2300: Duplicate identifier 'jQuery'.

...和

/node_modules/@types/jquery/index.d.ts(28,14): error TS2300: Duplicate identifier 'jQuery'.

tsconfig.json

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "lib": [
      "es5",
      "dom",
      "es2015.promise"
    ],
    "experimentalDecorators": true,
    "sourceMap": true,
    "allowSyntheticDefaultImports": true
  },
  "include": [
    "src/**/*"
  ],
  "exclude": [
    "node_modules",
    "scripts",
    "src/contracts"
  ]
}

有什么想法如何解决吗？

我是jira python的新手,我希望有一个列表,其中包含使用现有过滤器获得的票证.

我试过jira.filter(id)但是接收了有问题的列表,我只收到了过滤器的名称.使用jira.search_issue正在工作,但因为我的过滤器可以被其他人改变,我需要一些会考虑过滤器内容的变化.有任何想法吗？谢谢!

使用这样的代码:

var remarkAbstract = require("remark");
var remark = remarkAbstract();

let remark = remarkAbstract();
var ast = remark.process(input);

但它返回输出,如:

AssertionError: VFile {
  contents: '# header\n\n20 December 2012\n\n![alt](http://yo.io/)\n\ncontent1\n\ncontent2\n\n## header2\n',
  messages: =

我想获得AST树这样

我正在使用 angularjs 开发 ionic 移动应用程序，为了加密 ionic 应用程序的源代码，我们使用 Cordova 插件“crypt file”在构建时加密代码。在进行APK逆向工程后，我们发现根文件夹“assets/www”按预期加密，但通过使用“java反编译器”工具，我们可以访问“java代码”插件源代码并获得解密密钥。

那么，有没有什么办法可以加密或隐藏插件文件夹，让攻击者无法通过APK看到我们在应用中使用了哪些插件呢？

提前致谢

对不起，如果有人已经要求这个。我对 Stack 很陌生，我没有找到解决方案。

这是我缩小后从我的应用程序的使用中获得的堆栈。

这是我的 proguard 文件：

    # ionic
-keep class org.apache.cordova.** { *; }
-keep class …

这是我的原始代码：

Viewport = {
    rotate: function () {
        setTimeout(function () {
            this.startRotate();
        }, 1000);
    }    

    startRotate: function () {
        console.log('in')
    }
}

当我尝试运行 setTimeout 时：

setTimeout(this.startRotate(), 2000);  

它失败了，因为这样 setTimeoout 中的代码会立即运行..

在我的原始代码中，我得到“未定义不是函数”。

这是为什么？
