所以我有以下Dockerfile：在泊塢窗容器編譯libsass

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
我想在此基礎上依據建立libsass： https://gist.github.com/edouard-lopez/503d40a5c1a49cf8ae87
然而，當我嘗試建立與泊塢窗我得到的以下錯誤：
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

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
我不知道很多關於從源代碼編譯，所以任何解決方案，請帶我通過。你RUN cd libsass所以你需要
