docker - 从命名阶段进行复制失败，出现 `no such file or directory`

Question

想知道谁能提供帮助，因为我的所有搜索似乎都没有结果。

鉴于此docker文件:

# ------------ STAGE WKHTMLTOPDF

## madnight container needed due to qt, must have wkhtmltopdf with patched qt
FROM madnight/docker-alpine-wkhtmltopdf as madnight

# ------------ STAGE BASE LAYER
## Create a *base* image with all system dependencies
FROM php:7.1-fpm-alpine AS base

运行 docker build -t dev-test:latest -f docker/dev/Dockerfile .失败，

Step 23/31 : COPY --from=withPHPDependencies /source-code/ .
COPY failed: stat /var/lib/docker/overlay2/9eaa20ed309e8ffc27461fcf7809b9187a117de2dc318071713d696f27fdc078/merged/source-code: no such file or directory

本地文件被复制到 withPHPDependencies，因为 composer install步骤运行没有问题。我还注释掉了 .dockerignore中的所有内容并运行了 docker system prune -a
不知道我还能检查什么。

阿克!我瞎了。

Dockerfile不使用=定义环境变量。一旦删除它们，一切便开始工作。
