composer - 如何在其他软件包之前首先安装/优先安排特定软件包？

Question

I'd been setting up WordPress and obtaining its required plugins via composer for some years now, it works great, but I've given up trying to hack or be tricky when it comes to installing plugins that does not know how to use WP_SITEURL and also PaaS that doesn't support non-standard WordPress folder structure.

So I am wondering if I can still use composer to setup WordPress-core (or any other package) but I want it to be installed first.

Say in your composer.json, you have the following packages:

{
    "name": "test/composer-install-order",
    "type": "project",
    "repositories": [
    { "type": "composer", "url": "https://wpackagist.org" }
    ],
    "require": {
        "php": ">=7.2",
        "composer/installers": "~1.6.0",
        "johnpbloch/wordpress": "^4.9",
        "wpackagist-plugin/better-search-replace": "*",
        "wpackagist-plugin/bugherd": "*",
        "wpackagist-plugin/disable-emojis": "*"
    },
    "extra": {
    "installer-paths": {
        "public_html/wp-content/plugins/{$name}/": ["type:wordpress-plugin"],
        "public_html/wp-content/themes/{$name}/": ["type:wordpress-theme"]
    },
    "wordpress-install-dir": "public_html"
    },
    "config": {
        "preferred-install": "dist",
        "optimize-autoloader": true,
        "sort-packages": true
    }
}

The composer.json above says you required 3 plugins: better-search-replace, bugherd, and disable-emojis

But when you hit composer install:

➜  temp1 composer install
Loading composer repositories with package information
Updating dependencies (including require-dev)
Package operations: 7 installs, 0 updates, 0 removals

- Installing johnpbloch/wordpress (4.9.8): Loading from cache
- Installing wpackagist-plugin/disable-emojis (1.7.2): Loading from cache
Writing lock file
Generating optimized autoload files
➜  temp1

You'll only get 1 plugin inside wp-content/plugins folder. The reason for this is because when you check the print above, the 2 plugins better-search-replace and bugherd where installed first BEFORE the Wordpress core files johnpbloch/wordpress. So even composer extracted those 2 plugin packages to its correct folder, the johnpbloch/wordpress has removed them because it overwrote the wp-content/plugins folder.

The only way for this to work is if I install johnpbloch/wordpress first before the plugins, but I do not know if its possible since composer install via the composer.lock content.

Hope somebody can help.

Hi The Wolf,

Thanks for asking your question. The issue at root here is a conflict between how Composer works and the default way WordPress works.

If you want to use Composer to manage WordPress core as a dependent package, you have to use a specific non-standard installation option for WordPress in which core is installed in a subdirectory and the wp-content directory is set to a location outside of the core package. Rarst has a great microsite detailing the optimal setup. You can also check out my sample WordPress package starter package for inspiration. You can read more about installing core in a subdirectory and moving wp-content on the codex.

If you're interested in reading a little more about the reasoning for this issue, please see this thread in the installer repository in which the topic gets a bit more lengthy treatment.

Hope that helps!
