有人能帮我解决这个问题吗？
当我try 从laravel应用程序的dockerfile创建docker图像时，收到以下错误:
判断oniguruma...不
No package 'oniguruma' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables ONIG_CFLAGS and ONIG_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.命令"/bin/sh-c docker php ext install pdo mbstring"返回一个非零代码:1
这是我的Dockerfile:
FROM php:7
RUN apt-get update -y && apt-get install -y openssl zip unzip git
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
RUN docker-php-ext-install pdo mbstring
WORKDIR /app
COPY app /app # this copies all the app files to a folder called `app`
RUN composer install
CMD php artisan serve --host=0.0.0.0 --port=8000
EXPOSE 8000
以及docker命令来构建Dockerfile
sudo docker build -t test .
