NLTK Downloader

在pubspec.yaml中添加依赖项

[nltk_data] Error loading popular: <urlopen error [WinError 10054] An
[nltk_data]     existing connection was forcibly closed by the remote
[nltk_data]     host>

更新软件包时，我收到以下错误消息。

Answer 1

已解决

在“ dev_dependencies”部分下添加依赖项，无法在“ dependencies”部分下添加依赖项。

  dev_dependencies:
      flutter_test:
        sdk: flutter
      google_maps_flutter:
        git: 
          url: git://github.com/gerryhigh/plugins
          path: packages/google_maps_flutter
