我编写了以下Dockerfile来使用OpenPose构建图像(https://github.com/CMU-Perceptual-Computing-Lab/openpose)

这里也发生了两件奇怪的事情。1( 如果我用docker run -it openpose_image和cd opt/openpose/build && make all -j"$(nproc)"运行到目前为止构建的图像，我会得到同样的错误。2( 如果我先执行nvidia-docker run -it openpose_image，然后执行cd opt/openpose/build && make all -j"$(nproc)"，则构建运行平稳，成功结束，不会引发错误。有人能帮我弄清楚发生了什么事吗？感谢
我认为这是因为RUN语句不会进行shell扩展。我只是试着使用backticks(即make -j`nproc`(，它似乎可以
Shell扩展在RUN语句中确实有效。只需去掉双引号。
RUN printenv && cd opt/openpose/build && make all -n -j $(nproc)
