我正试图在docker容器中设置Monarc，我正处于运行composer的阶段。但不幸的是，这引发了以下错误：

我遵循此处提供的指南：https://github.com/monarc-project/MonarcAppFO/blob/master/INSTALL/INSTALL.ubuntu1804.md.
我的这个部分的dockerfile目前看起来像(在composer行失败，出现上面的错误(：
RUN mkdir -p /var/lib/monarc/fo
RUN git clone https://github.com/monarc-project/MonarcAppFO.git /var/lib/monarc/fo
WORKDIR /var/lib/monarc/fo
RUN mkdir -p data/cache
RUN mkdir -p data/LazyServices/Proxy
RUN chmod -R g+w data
RUN composer install -o
从链接上看，关于以root/sudo的身份运行它的行似乎很好。除此之外，我完全不知道这里出了什么问题。
您的composer版本已经过时。
只需升级composer，然后重试。
