Question

我正在使用React Native为Android创建项目，并尝试使用以下命令native-base安装npm install native-base --save。之后，当我使用react-native link链接库时，出现如下错误。

rnpm-install ERR! ERRPACKAGEJSON No package found. Are you sure this is a React Native project?

我遵循了本文档http://docs.nativebase.io/docs/GetStarted.html。我没有得到什么问题。请帮助

1-确保已在项目目录中完成npm install native-base --save

2-尝试npm i来解决依赖项问题，然后命令react-native run-android确保您的依赖项和“ node_modules”文件夹正常工作，并且项目可以运行。

如果没有“ android”或“ ios”文件夹，则可以使用命令react-native eject，然后链接软件包。

3-编写命令react-native link native-base，此命令将基于本机的程序包与本机完全链接。
但是，我建议您主要手动链接软件包。

您还可以尝试使用本机基础的先前版本，例如v 2.10.0。

感谢@AmirGorji @parashKorat帮助我。对我来说，这个问题来了，因为我已从清单文件中删除了android:roundIcon="@mipmap/ic_launcher_round"。当我再次输入react-native link时。我删除了它，因为添加图标后，它显示出缺少圆形图标的错误，暂时删除了。

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.namaztiming">

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

    <application
      android:name=".MainApplication"
      android:label="@string/app_name"
      android:icon="@mipmap/ic_launcher"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:allowBackup="false"
      android:theme="@style/AppTheme">
      <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
        android:windowSoftInputMode="adjustResize">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
      </activity>
      <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
    </application>

</manifest>

我不知道这是否是正确的解决方案，但就我而言，它解决了问题。
