如题，
针对ESP-IDF5.0,项目中要用到LVGL,通过https://components.espressif.com/search/org:lvgl，查到有注册库lvgl 8.3.0;
于是用idf.py add-dependency lvgl==8.3.0添加支持LVGL时，命令能成功。但在 idf.py set-target esp32s3时，提示如下错误：

是不是目前LVGL不支持idf-manager?

谢谢

这句有问题：idf.py add-dependency lvgl==8.3.0
需改为：idf.py add-dependency lvgl/lvgl==8.3.0

红色部分，如果不指明的话，默认会从 espressif 下找，但 espressif 又没有提供 lvgl，所以报错：

Code: Select all

Because project depends on espressif/lvgl (==8.3.0) which doesn't match any
versions, version solving failed.

这个相当于是一个维护者的 name。

另外，idf.py add-dependency lvgl==8.3.0 后，会在 main 目录下生成 idf_component.yml，你可以打开看下，类似如下：

Code: Select all

## IDF Component Manager Manifest File
dependencies:
  espressif/lvgl: "==8.3.0"
  ## Required IDF version
  idf:
    version: ">=4.1.0"
  # # Put list of dependencies here
  # # For components maintained by Espressif:
  # component: "~1.0.0"
  # # For 3rd party components:
  # username/component: ">=1.0.0,<2.0.0"
  # username2/component2:
  #   version: "~1.0.0"
  #   # For transient dependencies `public` flag can be set.
  #   # `public` flag doesn't have an effect dependencies of the `main` component.
  #   # All dependencies of `main` are public by default.
  #   public: true

你也可以直接改 espressif/lvgl 成 lvgl/lvgl。
如果你直接又执行了 idf.py add-dependency lvgl/lvgl==8.3.0，那么这个文件中会是：

Code: Select all

lvgl/lvgl: "==8.3.0"
espressif/lvgl: "==8.3.0"

你需要把 espressif/lvgl 这行删除。
