我在容器中使用的是alpine-linux。不久前，我遇到了与在pkg配置搜索路径中找不到Package cairo相同的错误。Node j.s安装画布问题我在Dockerfile中添加了以下片段：
# Install cairo for one of our frontend dependencies
RUN apk add --update --no-cache cairo
&& rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*
这让错误消失了(至少根据我的记忆，已经有几个月了)。
今天，运行docker-compose exec web yarn watch时再次出现此错误。以下是错误的完整输出：

Package cairo was not found in the pkg-config search path.
Perhaps you should add the directory containing `cairo.pc'
to the PKG_CONFIG_PATH environment variable
Package 'cairo', required by 'virtual:world', not found

经过一些浏览，我在任何地方都看不到任何cairo.pc文件，所以我如何确定需要采取什么步骤来教育我的yarn installcairo的位置？
这可以通过安装cairo-dev包轻松修复。
根据Alpine的软件包搜索，它将在/usr/lib/pkgconfig下安装cairo.pc，这很可能被gyp:检测到
