Question

我在Windows上安装了Flutter，并使用颤动医生检查了一切正常。我导入了Flutter插件。

现在，当我尝试通过Anroid Studio创建一个新的Flutter应用程序时，它永远不会结束。我得到了“创建Flutter项目”，就是这样。

消息区域包含“”C：\ Program Files \ Flutter \ flutter \ bin \ flutter.bat“--no-color create --template app --description”一个新的Flutter应用程序。“ - orok anykey。 co.il flutter_app4“ 它似乎停留在“建筑符号......”上。

我甚至将它留在了一夜之间，希望它能完成。

最后我必须杀了它。

编辑：看来我的flutter.bat文件正在循环播放。我试过扑了一下医生（回声一下），这就是我得到的。最后一部分永远循环。

Answer 1

这很可能是因为你将Flutter放在Program Files中，这需要管理员权限才能写入其缓存文件。

我有一个PR Open会导致更友好的错误，但我建议将Flutter移到非管理员用户可以写入的文件夹中。

Answer 2

选择选项后，当出现“正在创建新的 Flutter 项目”时，结束 Android Studio 进程并重新运行它然后 - 而不是创建项目 - 选择 打开项目并选择您之前创建的项目文件夹。

Answer 3

有同样的问题。

只需在管理员模式下运行Android Studio / IntelliJ即可。它有效。

Answer 4

对于Windows 10，这里有几种解决方案，我在这里与我分享正在解决的问题。

1。。“设置”中存在“设置Flutter SDK路径”。 Settings > Languages & Settings > Flutter > Flutter SDK Path

2。。以管理员模式

运行Android Studio / IntelliJ。

3。。您的项目位置路径文件夹名称为有效的Dart包名称。

Answer 5

就我而言，这就是问题所在-我选中了离线创建项目复选框。请确保未选中此复选框。

Answer 6

很久以前，我对同样的问题感到震惊。经过很多磕磕绊绊之后，我做对了。首先删除以前克隆的flutter文件并在用户文件夹中安装git。喜欢 C:\users\username\

克隆在你的git目录中颤动，设置路径 C:\users\username\git\flutter\bin

现在使用命令flutter doctor 如果您有android studio和intellij IDE，请在两者中安装flutter插件，然后创建一个新项目。

你们都准备好了

Answer 7

我在MacOS 10.13.4上遇到了同样的问题，当在Android Studio（3.1）上创建一个新的Flutter项目时，IDE卡住了，显示了短语＆＃34;构建符号＆＃34;在窗户的底部。

在cli上运行命令flutter run时，消息为：startup lock。

然后我从flutter sdk缓存中删除了锁： rm ./bin/cache/lockfile

这是https://github.com/flutter/flutter/issues/7768

报告的问题

Answer 8

我在Windows 10上遇到了同样的问题。确保Flutter SDK的路径出现在“ AS设置”中。设置>语言和设置> Flutter> Flutter SDK路径

Answer 9

我已禁用了防病毒（快速修复），并以管理员身份运行CMD并运行“ flutter ”命令。工作正常然后检查“ 扑打医生”命令，它也可以正常工作。

然后以管理员模式启动AS并创建flutter应用程序，它现在开始工作。

Answer 10

对我来说，这在Windows 10中有效：

Flutter SDK的位置：保留在c：\ Users <用户名> \ AppData \ Local
项目位置：保存在c：\ Users <用户名> \ AppData \ Local
以管理员模式启动Android Studio：这不是必需的，它在没有管理员权限的情况下可以正常工作
在创建新的Flutter项目时：离线创建项目（选择此选项）（同一篇帖子中的另一个答案是带有屏幕截图的，请不要选择它，但对我而言，只有在选择了此选项后，它才起作用选项）

创建项目花费了多少时间？ 2分钟

Answer 11

在windows中尝试以管理员身份运行android studio并创建新的flutter项目

Answer 12

将计算机连接到Internet，然后尝试创建项目这样可以解决问题
