如何在MAC中的php GD库中启用Webp支持 [英] How can I Enable Webp support in php GD library in MAC

问题描述

我已经使用自制软件安装了PHP PHP 7.2.0beta3. phpinfo表示已启用webmp支持，

I have installed PHP PHP 7.2.0beta3 using homebrew. The phpinfo shows that the webmp support is enabled,

但是当我尝试使用包装类转换图像时，它会显示此错误:

But when i try to convert an image using a wrapper class it shows this error:

未捕获的错误:调用/Users/rakibtg/Projects/PHP-ImageToWebp/ImageToWebp.php:37堆栈跟踪中未定义的函数imagewebp()...

Uncaught Error: Call to undefined function imagewebp() in /Users/rakibtg/Projects/PHP-ImageToWebp/ImageToWebp.php:37 Stack trace ...

如何使用Homebrew php安装环境在macOS中启用webp支持?

How I can enable webp support as well in macOS using homebrew php installed environment?

尝试以下操作:

brew reinstall php72 --with-webp

Or, failing that, try:

brew rm php72
brew install webp
brew install php72 --with-webp
