错误:无法在pubspec.yaml中找到目录条目 [英] Error: unable to find directory entry in pubspec.yaml

问题描述

我正在尝试从我的flutter应用程序中的外部程序包中添加资产 如下所述: https://flutter. dev/docs/development/ui/assets-and-images#bundling-of-package-assets

I am trying to add assets from an external package in my flutter application as mentioned here: https://flutter.dev/docs/development/ui/assets-and-images#bundling-of-package-assets

即使添加了这个不能为空的简单条目，我也得到了这个Error: unable to find directory entry in pubspec.yaml /project/location/<project_name>/packages.

I am getting this Error: unable to find directory entry in pubspec.yaml /project/location/<project_name>/packages even for adding this simple entry which cant be null.

  assets:
    - packages/

推荐答案

https://flutter.dev/docs/development/ui/assets-and-images#asset-images-in-package-dependencies 解释了如何从依赖关系中添加资产

https://flutter.dev/docs/development/ui/assets-and-images#asset-images-in-package-dependencies explains how to add assets from dependencies

  assets:
    - packages/some_package/backgrounds/background1.png

将从软件包some_package中添加资产lib/backgrounds/background1.png.

Would add asset lib/backgrounds/background1.png from package some_package.

来自程序包的资产尚不支持添加整个目录，您需要单独添加每个资产文件(不过，可以自动识别分辨率子目录中的文件)

Assets from packages do not support adding whole directories yet and you need to add each asset file individually (files from resolution sub-directories are recognized automatically though)

添加资产目录还不支持从应用程序包中添加目录树.仅会识别列出目录下的所有文件(同样包括分辨率子目录)

Adding an asset directory also does not support adding a directory tree from the application package. Only all files directly below a listed directory are recognized (again including resolution sub-directories)
