如何在MAC中的php GD库中启用Webp支持

我已经使用自制软件安装了PHP7.2.0beta3。

phpinfo

显示已启用webmp支持，

但是，当我尝试使用a转换图像时，会显示以下错误：

未捕获错误：调用/Users/rakibtg/Projects/PHP ImageTowBP/ImageTowBP.PHP:37堆栈跟踪中未定义的函数imagewebp（）

如何使用自制php安装环境在macOS中启用webp支持？

请尝试以下操作：

brew reinstall php72 --with-webp

否则，请尝试：

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

brew options <PACKAGENAME>

你在那个列表上看到了WebP吗？WBMP≠ 是的，这就是我所问的，它不再工作了，不能在PHP7.1.31上使用WebP，我不知道如何启用它it@AmauryLeproux看看这里。。。哼，没有sudo，我不能rm我的版本，也不能使用PECL，甚至尝试sudo都失败了。WEBP仍然不被称为函数：/
