我必须维护适用于Ruby 1.9.3的旧的Ruby on Rails 2.3.17应用程序，并希望将开发转移到Docker for OS X（Docker版本17.12.0-ce，构建c97c6d6），但主要是目标 - 在主机上拥有文件夹，以避免每次启动新容器时重新安装gem。我尝试使用使用主机目录的Docker卷并在那里安装所有gem。使用以下Dockerfile
FROM zedtux/ruby-1.9.3
RUN apt-get update -qq \
&& apt-get install -y \
build-essential \
libmysqlclient-dev \
libxml2-dev \
libxslt-dev \
libsasl2-2 \
libsasl2-dev \
nodejs \
git \
&& apt-get clean autoclean \
&& apt-get autoremove -y \
&& rm -rf \
/var/lib/apt \
/var/lib/dpkg \
/var/lib/cache \
/var/lib/log
VOLUME /app
VOLUME /bundler-cache
RUN echo "---\ngem: --no-ri --no-rdoc" >> ~/.gemrc
WORKDIR /app
和docker-compose.yml
version: "3.5"
services:
web:
build: .
ports:
- "3000:3000"
volumes:
- /Users/bosko/central_bundle_storage/app-gems:/bundler-cache
- ${PWD}:/app
environment:
GEM_HOME: /bundler-cache
GEM_PATH: /bundler-cache
BUNDLE_PATH: /bundler-cache
PATH: /bundler-cache/bin:$PATH
用以下构建和启动容器后
docker-compose run --rm web bash
我正在安装bundler和gem：
gem install bundler
bundle install
由于本机扩展（即nokogiri等）而必须构建的大多数宝石安装正确但我有memcached gem的问题。构建gem失败，出现以下错误：
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. [7/1778]

错误是由memcached gem的extconf.rb文件中的以下行引起的：
run("env CFLAGS='-fPIC #{LIBM_CFLAGS}' LDFLAGS='-fPIC #{LIBM_LDFLAGS}' ./configure --prefix=#{HERE} --without-memcached --disable-shared --disable-utils --disable-dependency-tracking #{$CC} #{$EXTRA_CONF} 2>&1", "Configuring libmemcached.")
但是，如果我仍然在容器的bash上进入/bundler-cache/gems/memcached-1.4.6/ext/libmemcached-0.32文件夹并执行上述命令的扩展版本：

一切顺利，没有任何问题。有没有人知道为什么会发生这种情况？如果出现问题，如何通过修复gem安装或适当的音量安装来解决这个问题？
