AWS lambda上的纱线？

Question

是否有人设法获得 yarn 安装并在AWS lambda上工作？

（我正在尝试创建一个可以构建小反应项目的函数）

目前，我已经在Docker映像中安装了纱线并工作（基于public.ecr.aws/lambda/provided：al2），但是在Lambda中运行它时纱线试图访问只读文件系统时，我会遇到权限错误。

Dockerfile摘要：

FROM public.ecr.aws/lambda/provided:al2
...
# Update yum
RUN yum -y update
# Install NodeJS
RUN curl -fsSL https://rpm.nodesource.com/setup_16.x \
    | bash - && yum -y install nodejs
# Install Yarn
RUN curl -fsSL https://dl.yarnpkg.com/rpm/yarn.repo \
    | tee /etc/yum.repos.d/yarn.repo && \
    rpm --import https://dl.yarnpkg.com/rpm/pubkey.gpg && \
    yum -y install yarn
# Copy Binaries
RUN cp -r \

    /usr/lib/node_modules \

RUN yarn config set prefix /tmp/yarn/
