我已经在rails API上使用相同的Dockerfile几个月了，突然它不再构建了。每次尝试安装racc时，我都会收到一个错误：

#11 7.201 Installing racc 1.6.0 with native extensions
#11 7.598 Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
#11 7.598
#11 7.598     current directory: /usr/local/bundle/gems/racc-1.6.0/ext/racc/cparse

#11 7.598 checking for rb_block_call()... *** extconf.rb failed ***
#11 7.598 Could not create Makefile due to some reason, probably lack of necessary
#11 7.598 libraries and/or headers.  Check the mkmf.log file for more details.  You may
#11 7.598 need configuration options.

奇怪的是，直到今天下午，它还能正常工作。这是我的dockerfile：

FROM ruby:2.7.4-alpine

ENV APP_PATH /api
ENV RAILS_PORT 3000

# install dependencies for application these are specific to alpine
RUN apk -U add --no-cache --update \

# navigate to app directory
WORKDIR $APP_PATH

COPY Gemfile ${APP_PATH}/Gemfile
COPY Gemfile.lock ${APP_PATH}/Gemfile.lock

RUN mkdir -p ${APP_PATH}/log && touch ${APP_PATH}/log/development.log

RUN bundle install

COPY . $APP_PATH
RUN gem install foreman

还有我的Gemfile
