laravel 将版本添加到 composer.json postAutoloadDump 失败

Question

我的 laravel 5.6 项目的 composer.json 没有“版本”说明符。

所以我添加到我的composer.json：

"version": "0.1.0"

之后，当我运行composer install、composer update foo/bar 或composer dump-autoload 时，出现以下错误：

> Illuminate\Foundation\ComposerScripts::postAutoloadDump
> @php artisan package:discover
PHP Fatal error:  Uncaught Error: Call to undefined method Symfony\Component\Process\ProcessUtils::escapeArgument() in phar:///usr/local/bin/composer/src/Composer/Util/ProcessExecutor.php:134

当我删除 version 说明符时，一切都按预期工作。

这是我的 composer.json

{
    "name": "myvendor/myproject",
    "description": "",
    "keywords": [],
    "license": "MIT",
    "version": "0.1.0",

        "laravel/tinker": "^1.0"
    },
    "require-dev": {
        "barryvdh/laravel-ide-helper": "^2.4",
        "doctrine/dbal": "^2.6",
        "filp/whoops": "^2.0",
        "friendsofphp/php-cs-fixer": "^2.10",
        "fzaninotto/faker": "^1.4",
        "mockery/mockery": "^1.0",

        "phpunit/phpunit": "^7.0"
    },
    "autoload": {
        "classmap": [
            "database/seeds",
            "database/factories"
        ],
        "psr-4": {
            "App\\": "app/"
        }
    },
    "autoload-dev": {
        "psr-4": {
            "Tests\\": "tests/"
        }
    },
    "extra": {
        "laravel": {
            "dont-discover": [
            ]
        }
    },
    "scripts": {
        "post-root-package-install": [
            "@php -r \"file_exists('.env') || copy('.env.example', '.env');\""
        ],
        "post-create-project-cmd": [
            "@php artisan key:generate"
        ],
        "post-autoload-dump": [
            "Illuminate\\Foundation\\ComposerScripts::postAutoloadDump",
            "@php artisan package:discover"
        ]
    },
    "config": {
        "preferred-install": "dist",
        "sort-packages": true,
        "optimize-autoloader": true
    },
    "minimum-stability": "dev",
    "prefer-stable": true
}

所以它告诉我Symfony\Component\Process\ProcessUtils::escapeArgument 是未定义的。我还找到了https://github.com/laravel/framework/issues/21281 和https://github.com/eyewitness/eye/issues/8，但我无法将它们放在一起来解决问题。

同样，当我从 composer.json 中删除 version 时，问题就消失了。

Answer 1

原来错误是我使用的composer版本引起的。

我使用的是 laradock 环境，composer --verison 是 1.5.5。将composer更新为1.6.3后，问题就消失了。

但是，如果你遇到同样的问题，你很可能会遇到同样的困难，在 laradock 的工作区容器中更新 composer。你不能简单地在那里composer selfupdate，因为由于权限设置，作曲家将临时文件移动到/usr/local/bin 时会遇到问题。

我通过将以下部分添加到我的 laradock/workspace/Dockerfile-72 来修复它：

#####################################
# Composer:
#####################################

## FIX laradock/workspace permission problem

USER root

RUN rm /usr/local/bin/composer

USER laradock

RUN cd /home/laradock && php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" && \
    php -r "if (hash_file('SHA384', 'composer-setup.php') === '544e09ee996cdf60ece3804abc52599c22b1f40f4323403c44d44fdfdd586475ca9813a858088ffbc1f233e9b180f061') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;" && \
    php composer-setup.php && \
    php -r "unlink('composer-setup.php');"

USER root 

RUN mv /home/laradock/composer.phar /usr/local/bin/composer

## ENDFIX

我想，问题是，https://github.com/laradock/workspace/blob/master/Dockerfile-72 不执行 composer-setup.php（请参阅此处@Raaghu 的答案：permission denied for composer in /usr/local/bin/）。

也许只需将其添加到 laradock/workspace Dockerfile 即可更轻松地解决问题：

USER root

RUN chown laradock:laradock /usr/local/bin/composer

但我没有测试这个设置，我不确定。
