如何更新phpunit 6和代码覆盖率5

Question

我使用phpunit 6.5.14与php-code-coverage 5.3.2一起使用。

我想更新phpunit和php代码覆盖率。然而，当我试图更新其中一个，它失败了，因为他们需要对方。

例如。呼叫

composer require --dev phpunit/phpunit ^7

在以下方面失败：

试图通过以下方式更新代码覆盖率

composer require phpunit/php-code-coverage ^6

在以下方面失败：

我还试图删除代码覆盖率，这样我就可以更新php-unit并重新安装它。但是把它移除

composer remove phpunit/php-code-coverage

不起作用，只需发出以下通知：

如何更新两个包？

Answer 1

我建议删除composer.lock和或vendor，因为Composer在这方面并不完美。通常根本就没有冲突。

然后更改composer.json.

• Then

• ，从中删除两个包，让composer重新决定可能的最高版本的：

作曲家需要phpunit/phpunit

您可以省略phpunit/php-code-coverage，因为它已经在phpunit/phpunit required packages中了。

Answer 2

我用--update-with-dependencies解决了它
