作曲家。错误：在有效的作曲家.json 上"Could not parse version constraint..."

Question

问题:Get无法解析有效composer.json的版本约束。

我有/srv/www/site/api/composer。json和/srv/www/site/frontend/composer.json。没有作曲家。在目录/srv/www/site/api/和/srv/www/site/frontend/

中锁定或vendor/

Api作曲家。Json和前端编写器。Json包含相同的文本:

{
    "minimum-stability": "stable",
    "require":
    {
        "doctrine/dbal": "*"
    },
    "autoload":
    {
        "psr-4":
        {
            "app\": "./"
        }
    }
}

。我运行。

cd /srv/www/site/api
composer install

并得到结果。好的。

Answer 1

删除用户目录中的.composer文件夹。For me /home/noopic/.composer在两个目录中成功安装。

但是如果我在前端运行

composer update
