在 Manjaro (Arch Linux) 上安装 Magento 2 ~ 缺少 php 扩展

Question

我正在我的系统上安装 Magento 2，经过一番折腾，我终于进入了 localhost 设置向导。在readiness-check-install屏幕出现以下问题（网上有几个解决方案，大部分我都试过了）：

错误： 1 个缺少 PHP 扩展：PHP 扩展 curl 重要的是我为此使用了 Manjaro，它是一个 Arch Linux 发行版。

1：问题是，arch linux 包商店里根本没有没有 php-curl 包，我认为 curl 扩展已经与 php 一起安装。

2：我检查了我的 php.ini 文件，没有一行扩展名=php_curl，只有扩展名=curl。

3: php -m 打印：

4：我用 brew for linux 安装了所有东西，所以我可以像这样检查 php 包：

brew info php@7.3
php@7.3: stable 7.3.13 (bottled) [keg-only]
General-purpose scripting language
https://www.php.net/
/home/linuxbrew/.linuxbrew/Cellar/php@7.3/7.3.13 (520 files, 86.2MB)

From: https://github.com/Homebrew/linuxbrew-core/blob/master/Formula/php@7.3.rb
==> Dependencies
Build: httpd ✘, pkg-config ✘, xz ✔
Required: apr ✔, apr-util ✔, argon2 ✔, aspell ✔, autoconf ✔, curl-openssl ✔, freetds ✔, freetype ✔, gettext ✔, glib ✔, gmp ✔, icu4c ✔, jpeg ✔, libpng ✔, libpq ✔, libsodium ✔, libzip ✔, openldap ✔, openssl@1.1 ✔, sqlite ✔, tidy-html5 ✔, unixodbc ✔, webp ✔, bzip2 ✔, libedit ✔, libxml2 ✔, libxslt ✔, zlib ✔
==> Caveats
To enable PHP in Apache add the following to httpd.conf and restart Apache:
LoadModule php7_module /home/linuxbrew/.linuxbrew/opt/php@7.3/lib/httpd/modules/libphp7.so

<FilesMatch \.php$>
SetHandler application/x-httpd-php
</FilesMatch>

Finally, check DirectoryIndex includes index.php
DirectoryIndex index.php index.html

The php.ini and php-fpm.ini file can be found in:
/home/linuxbrew/.linuxbrew/etc/php/7.3/

php@7.3 is keg-only, which means it was not symlinked into /home/linuxbrew/.linuxbrew,
because this is an alternate version of another formula.

If you need to have php@7.3 first in your PATH run:
echo 'export PATH="/home/linuxbrew/.linuxbrew/opt/php@7.3/bin:$PATH"' >> ~/.zshrc
echo 'export PATH="/home/linuxbrew/.linuxbrew/opt/php@7.3/sbin:$PATH"' >> ~/.zshrc

For compilers to find php@7.3 you may need to set:
export LDFLAGS="-L/home/linuxbrew/.linuxbrew/opt/php@7.3/lib"
export CPPFLAGS="-I/home/linuxbrew/.linuxbrew/opt/php@7.3/include"


Warning: php@7.3 provides a launchd plist which can only be used on macOS!
You can manually execute the service instead with:
php-fpm

我真的不知道如何防止这个错误。

Answer 1

我相信 ext-curl 是 Arch 的核心 PHP 包的一部分，这就是为什么你在 pacman 中找不到它的原因。我不认为默认启用它，您需要编辑相应的 /etc/php/php.ini 文件。您可能希望在 php-fpm.ini 中取消注释 ;extension=curl。你可能需要设置extension_dir，但这对于 Arch/pacman 来说不太可能。

我刚刚注意到您正在使用 brew for linux... 为什么？这甚至得到 Arch 的支持吗？你可以检查 /home/linuxbrew/.linuxbrew/etc/php/7.3/ 位置，看看为什么 curl 没有启用，或者只使用 pacman。请注意，cli 和 fpm 运行时有一个单独的 ini 文件。
