Question

由于flutter 1.9 flutter_web在flutter中合并。我正在尝试在chrome浏览器中运行初始flutter应用程序，但失败。操作系统是ubuntu 19.04

我成功使用的命令：扑扑升级

颤抖地创建test_1_9

cd test_1_9

颤动

该命令不起作用：

flutter运行-d chrome

=>找不到名称或ID与“ chrome”匹配的设备

我尝试使用google-chrome作为设备名称，结果相同

Answer 1

对于chrome之后仍无法检测到flutter config --enable-web的这些人。您应该检查一下自己的颤动是否在适当的分支中，要列出所有分支，请使用：

颤振通道

输出可能看起来像这样：

Flutter channels:  
   beta  
   dev  
   master  
*  stable

带星号前缀的项目表示您所在的分支。要切换到主分支，请尝试：

颤振通道主控

之后，您的flutter doctor可以列出chrome设备。

Answer 2

您通过flutter config --enable-web启用了网络支持吗？

此link的
参考

Answer 3

https://flutter.dev/docs/get-started/web

$ flutter channel master
$ flutter upgrade
$ flutter config --enable-web

$ flutter devices  //downloads sky_engine and sdk tools then shows a list of devices including chrome

$ flutter create test_app
$ flutter run -d chrome  //local host will run chrome

Answer 4

在我的情况下-扑扑医生给了我以下输出

[✗] Chrome - develop for the web (Cannot find Chrome executable at google-chrome)
    ! Cannot find Chrome. Try setting CHROME_EXECUTABLE to a Chrome executable.

与拱一样，二进制文件称为google-chrome-stable和/或google-chrome-unstable

export CHROME_EXECUTABLE=/usr/bin/google-chrome-stable

是使它工作所需的一切。

Answer 5

请按照以下步骤在网络上运行您的Flutter应用程序

1. flutter channel master (navigate to master branch)

2. flutter upgrade

3. flutter config --enable-web

4. flutter devices

5. flutter create web_app

6. flutter run -d chrome (run project on chrome)

Answer 6

您需要运行用于Web的服务器，然后可以在大概8080的端口上使用它。如果一切设置正确，则可以：

webdev serve

否则尝试：

   flutter packages pub global run webdev serve

Answer 7

还要确保从主版本升级颤振，而不是从稳定分支升级

Answer 8

您需要cd到flutter的安装工作区，然后运行：

git checkout master

Answer 9

如果您尝试使用dart开发Web应用程序，那么我的建议是创建新的Dart项目-> Angular Dart->成功创建angular dart后->然后打开终端->输入“ Webdev serve”
