haskell - 构建docker镜像时堆栈GHCJS项目初始化错误

Question

我正在尝试创建一个 docker 镜像作为 GHCJS 开发环境。

我在 Dockerfile 的这一行上收到一个错误，该行是使用堆栈初始化 GHCJS 模板项目:

运行 stack new helloWorld ghcjs

整个 Dockerfile 是:

FROM debian:latest

#update
RUN apt-get update
#install apt-utils and emacs
RUN apt-get install -y apt-utils emacs-nox
#install ghcjs dependencies
RUN apt-get install -y curl git libtinfo-dev alex happy nodejs-legacy nodejs
#install stack
RUN curl -sSL https://get.haskellstack.org/ | sh
#add stack to path
RUN echo "PATH=$PATH:/usr/local/bin/stack:/root/.local/bin" >> /root/.profile
#create and change into project directory
RUN mkdir /root/ghcjs/ && cd /root/ghcjs/
#initialize ghcjs project
RUN stack new helloWorld ghcjs
#add stack.yaml
ADD stack.yaml /root/ghcjs/helloWorld/
#install ghcjs
RUN stack setup

输出和错误是:

Downloading template "ghcjs" to create project "helloWorld" in helloWorld/ ...

The following parameters were needed by the template but not provided: author-email, author-name, category, copyright, github-username
You can provide them in /root/.stack/config.yaml, like this:
templates:
  params:
    author-email: value
    author-name: value
    category: value
    copyright: value
    github-username: value
Or you can pass each one as parameters like this:
stack new helloWorld ghcjs -p "author-email:value" -p "author-name:value" -p "category:value" -p "copyright:value" -p "github-username:value"

Looking for .cabal or package.yaml files to use to init the project.
Using cabal packages:
- helloWorld/helloWorld.cabal

Resolver 'lts-9.12' does not have all the packages to match your requirements.
    ghcjs-base not found

This may be resolved by:
    - Using '--solver' to ask cabal-install to generate extra-deps, atop the chosen snapshot.
    - Using '--omit-packages to exclude mismatching package(s).
    - Using '--resolver' to specify a matching snapshot/resolver

The command '/bin/sh -c stack new helloWorld ghcjs' returned a non-zero code: 1

在使用它创建新项目之前需要安装 ghcjs(ghcjs-base 将成为 ghcjs 安装的一部分)。
