无法在 Mac Big Sur 上安装 PHP yaml 扩展

Question

运行pecl install yaml出现configure: error: 'yaml.h' header not found

我通过 Homebrew brew install php@7.4和 libyaml brew install libyaml了 PHP 7.4.14 ，但仍然看到同样的错误。

我还尝试重新安装 xcode 开发工具，以及使用 sudo 运行 pecl，但每次仍然出现相同的错误。 来自下面pecl的完整output。

Answer 1

也许你应该检查一下。

Please provide the prefix of libyaml installation [autodetect] :

今天我得到了同样的东西。 我尝试输入 libyaml 前缀解决。

这是步骤：

步骤1

$brew uninstall libyaml
Uninstalling /opt/homebrew/Cellar/libyaml/0.2.5... (10 files, 369.7KB)

第2步

$brew install libyaml 
==> Downloading https://github.com/yaml/libyaml/archive/0.2.5.tar.gz
Already downloaded: /Users/**/Library/Caches/Homebrew/downloads/688fdcea5b88140cb83d1f72e3a77fa76b6560f0d66eabcea7d54cf9f06d5e72--libyaml-0.2.5.tar.gz
==> ./bootstrap
==> ./configure --prefix=/opt/homebrew/Cellar/libyaml/0.2.5
==> make install
🍺  /opt/homebrew/Cellar/libyaml/0.2.5: 10 files, 369.7KB, built in 12 seconds

step3复制 step2 中的前缀。

#In this case,It's
/opt/homebrew/Cellar/libyaml/0.2.5

第4步

$sudo pecl install yaml
Password:
downloading yaml-2.2.1.tgz ...
Starting to download yaml-2.2.1.tgz (40,977 bytes)
............done: 40,977 bytes
8 source files, building
running: phpize
Configuring for:
PHP Api Version:         20160303
Zend Module Api No:      20160303
Zend Extension Api No:   320160303
Please provide the prefix of libyaml installation [autodetect] : 

step5 粘贴您在 step3 中复制的信息，按回车键。

Please provide the prefix of libyaml installation [autodetect] : /opt/homebrew/Cellar/libyaml/0.2.5

终于成功了。

Answer 2

使用 brew 安装 libyaml 后，将路径复制到 libyaml 并在 pecl 要求提供前缀时粘贴。 就我而言，前缀是： /opt/homebrew/Cellar/libyaml/0.2.5
