“未安装Flutter Code扩展名”但是已经安装好几个月了 [英] "Flutter Code extension not installed" but it's been installed for months

问题描述

几个月来一直在Mac上使用Flutter和VSCode没问题，但是突然flutter医生产生了这个问题：

Have been using Flutter with VSCode on Mac for months without issues, but suddenly flutter doctor produces this:

[✓] Flutter (Channel beta, v0.5.1, on Mac OS X 10.13.4 17E202, locale en-US)

我可以确认已安装颤振，自从我开始使用它以来，没有任何变化。另外，在我更新颤振（今天）之前，颤振医生在VSCode下读取为：

I can confirm that flutter is installed, and nothing has changed since I started using it. Additionally, before I updated flutter (today), flutter doctor read, under VSCode, as:

[!] VS Code (version 1.24.1)
• VS Code at /Applications/Visual Studio Code.app/Contents
• Dart Code extension not installed; install from
  https://marketplace.visualstudio.com/items?itemName=Dart-Code.dart-code

但是，升级后似乎无法找到飞镖的问题可能已得到解决。

However, post-upgrade that seems the inability to find dart might have been fixed.

几天前有一篇帖子此处表示暂时不准确，因此我尝试运行该项目，并得到以下错误堆栈：

There is a post from a few days ago here that indicates flutter doctor may just be inaccurate for the time being, so I tried to run the project, and got the following error stack:

任何想法

推荐答案

VSCode中的一项更改使扩展检测失败。可以忽略此警告。

There was a change in VSCode that broke extensions detection. It's safe to ignore this warning.

有关此问题，请参阅Danny Tuppeny的完整评论这里。

对于stacktrace，有两件事：

For the stacktrace there are two things:

• 资产 ios / Flutter / flutter_assets / fonts / MyFlutterApp.ttf 不是
  找到


• 令人沮丧的问题

• The asset "ios/Flutter/flutter_assets/fonts/MyFlutterApp.ttf"was not found
• The issue with obsvervatory

您是否检查资产是否仍然存在？
没有它，该项目将无法编译，天文台问题可能与此有关。

Did you check the asset still exists? The project does not compile without it, and the observatory issue may be related to this.
