我一直致力于使用 SQL 数据库对简单的 Ruby on Rails API 进行 docker 化，但遇到了以下错误：
ERROR: It looks like you're trying to use Nokogiri as a precompiled native gem on a system with glibc < 2.17:
/lib/aarch64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by /usr/local/bundle/gems/nokogiri-1.13.3-aarch64-linux/lib/nokogiri/3.0/nokogiri.so) - /usr/local/bundle/gems/nokogiri-1.13.3-aarch64-linux/lib/nokogiri/3.0/nokogiri.so
If that's the case, then please install Nokogiri via the `ruby` platform gem: gem install nokogiri --platform=ruby or: bundle config set force_ruby_platform true
Please visit https://nokogiri.org/tutorials/installing_nokogiri.html for more help.
这是我的dockerfile

RUBY VERSION
ruby 3.0.0p0
BUNDLED WITH

请注意，我正在使用 M1 Macbook 机器 我对 Ruby 还是个新手，所以这可能是一个愚蠢的问题，导致了所有这些麻烦
看起来这确实是由于您使用的是 ARM 平台（Mac M1 是 ARM 处理器）而导致的。
错误消息中的路径也以某种方式显示了这一点：
/usr/local/bundle/gems/nokogiri-1.13.3-aarch64-linux/lib/nokogiri/3.0/nokogiri.so
aarch64 是 ARM 64 位架构的另一个名称。
为了克服这个问题，您必须使用与 MySQL 容器相同的技巧：将其交换到 linux/x86_64 平台。
所以，在你的 docker-compose.yml 中，你应该有：
## the file above this stays the same
app:
platform: linux/x86_64
## the file below this stays the same
并调整您的 Gemfile.lock，该行
nokogiri (1.13.3-arm64-darwin)
应该成为
nokogiri (1.13.3-x86_64-linux)
然后，至少重建该容器：
docker compose down
docker compose up --build
