我的laravel 5.6项目的作曲家。
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，发生以下错误：
> IlluminateFoundationComposerScripts::postAutoloadDump
> @php artisan package:discover
PHP Fatal error: Uncaught Error: Call to undefined method SymfonyComponentProcessProcessUtils::escapeArgument() in phar:///usr/local/bin/composer/src/Composer/Util/ProcessExecutor.php:134

当我删除version指示符时，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",
"type": "project",
"require": {
"php": "^7.1.3",
"fideloper/proxy": "^4.0",
"laravel/framework": "5.6.*",
"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",
"nunomaduro/collision": "^2.0",
"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SymfonyComponentProcessProcessUtils::escapeArgument不确定。我还找到了https://github.com/laravel/framework/issues/21281和https://github.com/eyewitness/eye/eye/issues/8，但是我在整理问题的情况下都遇到了问题。
再次，当我从composer.json中删除version时，问题已经消失了。
结果表明，错误是由我使用的作曲家版本引起的。
我使用的是Laradock环境，composer --verison是1.5.5。将作曲家更新为1.6.3后，问题已经消失。
但是，如果您遇到相同的问题，您很可能会遇到相同的困难，并在Laradock的工作区容器中更新作曲家。您不能简单地在那里composer selfupdate，因为由于权限设置，作曲家会在将临时文件移至/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
我猜，问题是，https：//github.com/laradock/workspace/blob/master/master/dockerfile-72不执行Composer-setup.php(请参阅@raaghu的答案：在此处参见答案：拒绝许可作曲家/usr/local/bin/(。
也许只需将其添加到laradock/workspace dockerfile：
，就可以更容易解决问题。USER root
RUN chown laradock:laradock /usr/local/bin/composer
但我没有测试此设置，我不确定。
