构建MedusaJS Docker镜像时遇NPM EUNSUPPORTEDPROTOCOL错误求助

构建MedusaJS Docker镜像时npm install报错
我正在构建MedusaJS的Docker镜像，前面步骤都正常，但执行Dockerfile里的RUN npm install --loglevel=error命令时出问题了。我对NPM了解不多，也没修改过仓库自带的Dockerfile。
错误输出

解决办法
这个错误核心是package.json里用到了NPM的link:协议依赖，但当前构建环境不支持该协议，或者本地依赖未正确同步到容器中。可以按以下步骤排查：
- 锁定兼容的NPM版本：Dockerfile里升级到
npm@latest可能存在兼容问题，换成对link:协议支持更稳定的版本，比如8.x系列。修改Dockerfile对应行：RUN npm install -g npm@8.19.2 - 检查本地依赖是否被复制：
link:docs-util/typedoc-plugins/typedoc-frontmatter-plugin是本地项目依赖，要确保docs-util目录没被.dockerignore忽略，并且构建时已经复制到容器内。 - 替换为公开包依赖：如果这个插件是已发布的npm包，直接把
link:开头的依赖替换成包名+版本号，比如："typedoc-frontmatter-plugin": "^1.0.0" - 配置NPM工作区：如果是项目内的工作区依赖，确保
package.json里配置了workspaces字段，且Docker构建时复制了整个工作区文件，而非仅单个package.json。
