在运行docker build时，我收到一个错误，缺少core-js依赖项。在运行npm的建议安装命令时，出现另一个错误。我试图恢复到较早的几个分支，但没有雪茄。
docker build .上的错误是：

我尝试运行npm的建议，结果是：

我很困惑。我不确定我是如何缺少core-js模块的，因为上次运行构建（几天前）时，我没有遇到任何问题。知道这里发生了什么吗？
Dockerfile：
FROM node:lts-alpine as updraft-frontend-build-stage
#install http server
RUN npm install -g http-server
#make app folder in current directory
WORKDIR /app
#copy package.json and package-lock.json
COPY package*.json ./
#install project dependencies
RUN npm install
#copy in project files & folders
COPY . .
#build app with minification
RUN npm run build
# EXPOSE 8080
# CMD ["http-server", "dist"]
#production stage
FROM nginx:stable-alpine as updraft-frontend-production-stage
COPY --from=updraft-frontend-build-stage /app/dist /usr/share/nginx/html
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]
更新：
尝试在没有缓存层的情况下运行docker build，但那里也没有运气。
答案 0 :(得分：4)
NPM不会安装缺少的文件，因为它们是core-js的一部分。正在运行
npm i -S core-js@2.5.7
成功了！
