docker build image, which failed to solve: error from sender: context canceled Error occurs when compiling image in pycharm terminal, but there is no problem when pycharm is closed. I found that pycharm locks the files to be compiled, which causes docker to have no permission to access them. Eventually, I discovered that the files in the current directory, including the internal .idea files in pycharm, were compiled, making docker unable to access them. Finally, I added .idea to .dockerignore and the problem was solved. enter image description here
