尝试安装guzzlehttp/guzzle时
composer require guzzlehttp/guzzle
我收到以下问题消息

Using version ^7.5 for guzzlehttp/guzzle
./composer.json has been updated 
Running composer update guzzlehttp/guzzle

  Problem 1
    - Root composer.json requires guzzlehttp/guzzle ^7.5 -> satisfiable by guzzlehttp/guzzle[7.5.0, 7.5.x-dev].
    - guzzlehttp/guzzle[7.5.0, ..., 7.5.x-dev] require guzzlehttp/psr7 ^1.9 || ^2.4 -> found guzzlehttp/psr7[dev-master, 1.9.0, 1.x-dev, 2.4.0, ..., 2.4.x-dev (alias of dev-master)] but the package is fixed to 2.1.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.                                                                                                                                                     
  Problem 2                                                                                                                                                           
    - guzzlehttp/guzzle[7.5.0, ..., 7.5.x-dev] require guzzlehttp/psr7 ^1.9 || ^2.4 -> found guzzlehttp/psr7[dev-master, 1.9.0, 1.x-dev, 2.4.0, ..., 2.4.x-dev (alias of dev-master)] but the package is fixed to 2.1.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.                                           
    - codeception/module-phpbrowser 1.0.2 requires guzzlehttp/guzzle ^6.3|^7.0 -> satisfiable by guzzlehttp/guzzle[7.5.0, 7.5.x-dev].
    - codeception/module-phpbrowser is locked to version 1.0.2 and an update of this package was not requested.                                                       

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require guzzlehttp/guzzle:*" to figure out if any version is installable, or "composer require guzzlehttp/guzzle:^2.1" if you know which you need.

我需要使用稳定版本的guzle。
我已经读到了这个问题，建议删除composer.lock文件，以便运行composer install或composer update。但我想知道在这种情况下，建议的解决方案是什么？
