Laravel版本：7.24
我只是想让作曲家要求laravel / telescope，并且作曲家安装失败。
Using version ^4.0 for laravel/telescope
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Installation request for laravel/telescope ^4.0 -> satisfiable by laravel/telescope[4.x-dev, v4.0.0].
- Can only install one of: laravel/framework[v7.28.1, 8.x-dev].
- Can only install one of: laravel/framework[8.x-dev, v7.28.1].
- Can only install one of: laravel/framework[8.x-dev, v7.28.1].
- Conclusion: install laravel/framework 8.x-dev
- Installation request for laravel/framework (locked at v7.28.1, required as ^7.24) -> satisfiable by laravel/framework[v7.28.1].
Installation failed, reverting ./composer.json to its original content.

我遇到了同样的问题。
composer require laravel/telescope "^2.0"
成功
- Installation request for laravel/framework (locked at v7.28.1, required as ^7.24) -> satisfiable by laravel/framework[v7.28.1].
告诉您发生了什么。您正在处理的项目已锁定为laravel / framework v7.28.1。当前版本的Telescope需要laravel / framework ^ 8.0。也许您将能够使用望远镜v3.0。

以下对我有用
private EditText editTextUsername, editTextPhone;
private Button buttonSave;
private FirebaseDatabase db;
public DatabaseReference databaseReference;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_edit_profile);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// firebaseAuth = FirebaseAuth.getInstance();
editTextUsername = findViewById(R.id.editTextUsername);
editTextPhone = findViewById(R.id.editTextPhone);
buttonSave = findViewById(R.id.buttonSave);
db = FirebaseDatabase.getInstance();
databaseReference = db.getReference();
buttonSave.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
String username = editTextUsername.getText().toString();
databaseReference.setValue(username);
}
});
}

答案 4 :(得分：-1)
尝试一下： 作曲家需要laravel / telescope“ ^ 1.2”或 作曲家需要laravel / telescope“ ^ 2.0”
