在Docker容器中编译libsass

Question

因此，我有以下Dockerfile：

############################################################
# Based on Ubuntu
############################################################

FROM ubuntu:trusty
MAINTAINER OTIS WRIGHT

# Add extra software sources

RUN apt-get update -qq

# Libsass requirements.

RUN apt-get install -y curl git build-essential automake libtool

# Fetch sources

RUN git clone https://github.com/sass/libsass.git
RUN git clone https://github.com/sass/sassc.git libsass/sassc

# Create configure script

RUN cd libsass
RUN autoreconf --force --install
RUN cd ..

# Create custom makefiles for **shared library**, for more info read:
# 'Difference between static and shared libraries?' before installing libsass  http://stackoverflow.com/q/2649334/802365

RUN cd libsass
RUN autoreconf --force --install
RUN ./configure --disable-tests --enable-shared --prefix=/usr 
RUN cd ..

# Build the library

RUN make -C libsass -j5

# Install the library

RUN make -C libsass -j5 install

我正在尝试基于以下要点构建libsass：https://gist.github.com/edouard-lopez/503d40a5c1a49cf8ae87

然而，当我尝试使用docker构建时，我得到了以下错误：

Step 11 : RUN git clone https://github.com/sass/libsass.git
 ---> Using cache
 ---> d1a4eef78fa5
Step 12 : RUN git clone https://github.com/sass/sassc.git libsass/sassc
 ---> Using cache
 ---> 435410579641
Step 13 : RUN cd libsass
 ---> Using cache
 ---> f0a4df503d85
Step 14 : RUN autoreconf --force --install
 ---> Running in a9b0d51d6ee3
autoreconf: 'configure.ac' or 'configure.in' is required
The command '/bin/sh -c autoreconf --force --install' returned a non-zero code: 1

我不太了解从源代码编译，所以任何解决方案，请带我通过。

RUN cd libsass不会为您更改目录，因此您需要为命令添加路径或使用WORKDIR指令
