好的,这超出了我的理解.我真的不知道这里到底有什么问题,但有什么问题.我快要撞墙了,快要摔死了,但什么都没发生.有什么好心的人可以帮我吗.

这是我的Dockerfile-

FROM golang:1.7-alpine
RUN echo http://dl-4.alpinelinux.org/alpine/edge/testing >> /etc/apk/repositories
RUN apk update && apk upgrade && apk add --no-cache bash git openssh alpine-sdk libgit2

RUN pkg-config --print-errors --exists libgit2

我已经在这里提出了建议-How do I install libgit2 on Alipne linux

这是最终结果-

Step 4 : RUN pkg-config --print-errors --exists libgit2
 ---> Running in f69f97142e81
Package libgit2 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libgit2.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libgit2',required by 'world',not found
The command '/bin/sh -c pkg-config --print-errors --exists libgit2' returned a non-zero code: 1

那是什么错呢？为什么看不到已安装的libgit2(0.24.1-r0).我真的尝试了所有可能的方法来在Docker容器中构建并安装此软件包,但我不能简单地做到这一点.我不知道怎么了.请帮我.

我的Dockerfile中的最后一条命令实际上是从这里获取的http://lists.subsurface-divelog.org/pipermail/subsurface/2014-November/015646.html

当然,这里描述的问题和我遇到的问题是不同的

任何有兴趣自行完成工作的人都可以遵循-

FROM golang:1.7-alpine
ENV TARGET venv
RUN echo http://dl-4.alpinelinux.org/alpine/edge/testing >> /etc/apk/repositories
RUN apk update && apk upgrade && apk add --no-cache bash git openssh alpine-sdk libcurl
RUN apk update && apk add cmake
RUN git clone git://github.com/libgit2/libgit2.git
WORKDIR $GOPATH/libgit2
RUN git checkout v0.24.0 && rm -rf build && mkdir build && cd build \
    && cmake .. -DCMAKE_INSTALL_PREFIX=$TARGET -DBUILD_CLAR=OFF && cmake --build . --target install
ENV PKG_CONFIG_PATH /go/libgit2/build/venv/lib/pkgconfig:$PKG_CONFIG_PATH

对于更简单,更清洁的方法,请遵循公认的答案.这仅具有具有libgit2版本的优点,该版本尚无法通过apk获得.

还有一件事–DBUILD_CLAR = OFF因为我不想在图像中安装Python只是为了运行测试
