【问题描述】：

我是 Flutter 的新手，我刚刚观看了一个关于在我的 MacBook Pro 上设置 Flutter 的在线视频，我刚刚创建了我的第一个项目并尝试在我的系统连接到 Internet 时运行它，但出现以下错误

Launching lib/main.dart on sdk gphone x86 arm in debug mode...
Running Gradle task 'assembleDebug'...
Exception in thread "main" java.lang.RuntimeException: Could not load wrapper properties from '/Users/bright/AndroidStudioProjects/second_flutterapp/android/gradle/wrapper/gradle-wrapper.properties'.

我在这里看到了很多这样的问题，但没有解决我的问题...我尝试删除“gradle-wrapper.jar”并替换“distributionUrl=https://services.gradle.org/distributions/gradle -xxx-all.zip 到 gradle-wrapper-properties 文件上的 gradle-6.4.1-all.zip” 并在我的终端上运行命令“flutter run”，但仍然出现相同的错误

我尝试过“颤振医生”，结果如下所示

我知道我还没有安装 Xcode，我稍后会安装，但我不确定这是否是问题所在 #我做错了什么？

【问题讨论】：

我发现了错误...当我复制新的分发链接时，我复制了一些错误...而不是 distributionUrl=services.gradle.org/distributions/gradle-6.7-all.zip..... 我复制并粘贴了（@ 987654322@ 到 gradle-6.7-all.zip）当我改变它时，一切都开始工作了

【解决方案1】：

查看路径，错误中明确表示：

Caused by: java.net.URISyntaxException: Illegal character in path at index 62: https://services.gradle.org/distributions/gradle-x.x.x-all.zip to gradle-6.7-all.zip

检查services.gradle.org/ distributions/中的文件gradle-xxx-all.zip时，gradle-6.7-all .zip 被发现。因此，复制分发路径时出错可能是一个重要因素。正确的文件应该是 gradle-6.7-all.zip。

另外，您提到这是第一次在您的 MacOS 中设置 Flutter。有了这个，您可以随时查看 Flutter 文档中关于 macOS install 的指南，了解任何遗漏的步骤/过程。
