我在页面上评论了一个未解决的GH 问题react-testing-library。提前致谢
网上有很多人用不同的方式问同样的问题,但没有明确的答案。任何人都可以理解到足以解释为什么docker build当package-lock.json应用程序中存在文件时会失败,而当文件不存在时会成功运行吗?貌似跟npm有关,但是不清楚。
每个人都说删除package-lock.json,但它存在是有原因的。
注意: npm install在我的本地机器上工作正常,只是在 docker 容器中失败。
如果我有这个 Dockerfile:
# First Stage: Builder
FROM node:13.12.0-alpine AS build
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build

并运行这个:
