Build 在Docker容器中编译libsas

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

我正试图基于以下要点构建

libsass

：

但是，当我尝试使用docker构建时，会出现以下错误：

Step 11 : RUN git clone https://github.com/sass/libsass.git

Step 12 : RUN git clone https://github.com/sass/sassc.git libsass/sassc

 ---> 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

我对从源代码进行编译了解不多，所以任何解决方案都请带我看。

Docker不会为您更改目录

运行cd-libsass

，因此您需要设置命令路径或使用

WORKDIR
