尝试mimemagic 0.3.10在 Ruby on Rails 项目中安装时遇到以下错误。注意，它是在Windows环境下运行的。这是最相关的错误堆栈跟踪：

Fetching mimemagic 0.3.10

Could not find MIME type database in the following locations:

"/usr/share/mime/packages/freedesktop.org.xml"]

Ensure you have either installed the shared-mime-info package for your
distribution, or
obtain a version of freedesktop.org.xml and set FREEDESKTOP_MIME_TYPES_PATH to
the location
of that file.

This gem might be installed …

尝试使用该flutter run命令运行 Flutter 应用程序会产生以下错误：

No `<meta-data android:name="flutterEmbedding" android:value="2"/>` in   "..\src\main\AndroidManifest.xml"

这是我的AndroidManifest.xml文件：

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

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

    <application android:name="${applicationName}" android:label="simple_material_app" android:icon="@mipmap/ic_launcher">
        <activity android:name=".MainActivity"
                  android:launchMode="singleTop"
                  android:theme="@android:style/Theme.Black.NoTitleBar"
                  android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection"
                  android:hardwareAccelerated="true"
                  android:windowSoftInputMode="adjustResize">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>
</manifest>

我知道错误消息提供了一个明显的解决方案，但我想在这里发布我的答案，以便其他遇到此错误的人可以快速解决它。
