FROM红宝石：2.5.1-slim或ruby-2.5.1-alpine引发以下错误，我如何使用较小的占位面积作为红宝石，因为它似乎没有使用上述任何选项喜欢使用。运行捆绑软件安装命令时发生此错误

An error occurred while installing nokogiri (1.8.4), and Bundler cannot

Make sure that `gem install nokogiri -v '1.8.4' --source 'http://rubygems.org/'`
succeeds before bundling.

First of all, try to run gem install nokogiri manually and check the log as suggested in the output above:

I recently had a problem while installing the nokogiri gem too. So I opened my mkmf.log file and found the reason of the problem there (the stdio.h library was missing out of the distribution):

"gcc -o conftest -I/usr/local/include/ruby-2.5.0/x86_64-linux-musl -I/usr/local/include/ruby-2.5.0/ruby/backward -I/usr/local/include/ruby-2.5.0 -I.    -O3 -ggdb3 -Wall -Wextra -Wno-unused-parameter -Wno-parentheses -Wno-long-long -Wno-missing-field-initializers -Wno-tautological-compare -Wno-parentheses-equality -Wno-constant-logical-operand -Wno-self-assign -Wunused-variable -Wimplicit-int -Wpointer-arith -Wwrite-strings -Wdeclaration-after-statement -Wimplicit-function-declaration -Wdeprecated-declarations -Wmisleading-indentation -Wno-packed-bitfield-compat -Wsuggest-attribute=noreturn -Wsuggest-attribute=format -Wduplicated-cond -Wno-maybe-uninitialized  -fPIC  conftest.c  -L. -L/usr/local/lib -Wl,-rpath,/usr/local/lib -L. -fstack-protector -rdynamic -Wl,-export-dynamic     -Wl,-rpath,/usr/local/lib -L/usr/local/lib -lruby  -lpthread -ldl -lcrypt -lm   -lc "

The problem was solved by installing the libc-dev package for me.

So. To solve your problem you should iteratively run gem install nokogiri command, check mkmf.log file after each failure and fix missing dependencies until the package is installed.

BTW here's my final list of dependencies which was enough to install Rails in Alpine:


echo "http://dl-cdn.alpinelinux.org/alpine/edge/testing" >> /etc/apk/repositories \
  && apk update \
  && apk add --update-cache postgresql-client nodejs \
    libffi-dev readline sqlite build-base postgresql-dev \
    libc-dev linux-headers libxml2-dev libxslt-dev readline-dev gcc libc-dev \
  && rm -rf /var/cache/apk/*

尝试：运行sudo gem install nokogiri。它将安装最新版本的nokogiri。然后将Gemfile.lock文件中的nokogiri版本更新为您刚刚安装的nokogiri最新版本。最后运行bundle install。也许会有所帮助。为我工作。
