### Q&A
Q1. I encountered the following problems when using the package manager

```
  HINT: Please check manifest file of the following component(s): main

  ERROR: Because project depends on esp-radar (2.*) which doesn't match any
  versions, version solving failed.
```

A1. For the examples downloaded by using this command, you need to comment out the override_path line in the main/idf_component.yml of each example.

Q2. I encountered the following problems when using the package manager

```
Executing action: create-project-from-example
CMakeLists.txt not found in project directory /home/username
```

A2. This is because an older version packege manager was used, please run `pip install -U idf-component-manager` in ESP-IDF environment to update.
