【问题描述】：

我想在 Symfony 4 项目中使用 Webpack Encore，当我按照 Yarn https://yarnpkg.com/lang/en/docs/install/ 的安装指南进行操作时，我收到以下错误消息：

# yarn install
yarn install v1.5.1
info No lockfile found.
[1/4] Resolving packages...
[2/4] Fetching packages...
error @symfony/webpack-encore@0.17.1: The engine "node" is incompatible with this module.
Expected version ">=6.0.0". error An unexpected error occurred: "Found incompatible module".
info If you think this is a bug, please open a bug report with the information provided
in "/var/www/html/jobeet/yarn-error.log".

我做了什么

我使用了这个 Docker 镜像：php:7.2-fpm

apt-get install apt-transport-https \
                gnupg -y --no-install-recommends

echo "alias nodejs=node" >> ~/.bashrc && \
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - && \
echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list && \
apt-get update && \
apt-get install yarn -y && \
apt-get clean && \
yarn config set proxy http://user:password@proxy:port && \
yarn config set https-proxy http://user:password@proxy:port

之后，当我使用yarn install 时，我收到了错误消息。

我的 Webpack Encore 版本：

# composer show | grep encore
symfony/webpack-encore-pack         v1.0.2             A pack for Symfony...

yarn install 尝试获取@symfony/webpack-encore@0.17.1。怎么修改？

如果我使用yarn install --ignore-engines，它可以工作...

yarn install v1.5.1
