我是flutter的新手，我刚刚在MacBook pro上观看了一段关于设置flutter的在线视频，我刚刚创建了我的第一个项目，并试图在我的系统连接到互联网时运行它，但在下出现了此错误

我看到过很多这样的问题，这里有答案，但没有解决我的问题。。。我已尝试删除"；gradle wrapper.jar"；以及替换"；distributionUrl=https://services.gradle.org/distributions/gradle-x.x.x-all.zip至等级-6.4.1-全拉链"；在gradle包装器属性文件上；颤振运行"；在我的终端上，但仍然得到相同的错误
我试过"；扑动医生"；这给了我下面的结果

我知道我还没有安装Xcode，我稍后会安装，但不确定这是否是问题所在#我做错了什么？
查看路径，错误清楚地表明：
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
在services.gradle.org/distributions/中检查文件gradle-x.x.x-all.zip时，它不存在，而找到gradle-6.7-all.zip。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.
此外，您提到这是Flutter第一次在您的MacOS中设置。有了这个，您可以随时查看Flutter文档中关于macOS安装的指南，以查找任何遗漏的步骤/过程。
错误显示"distributionUrl=https://services.gradle.org/distributions/gradle-xxx-all.zip至等级-6.4.1-全拉链"；
