Question

Makefile：

SHELL=/bin/bash
.PONY: stamp diff
.DEFAULT_GOAL := all

diff:
    diff <(./stamp.txt) <(docker-compose -f docker-compose.test.yml up)

stamp:
    docker-compose -f docker-compose.test.yml up > stamp.txt

all: stamp diff

输出：

$ make
docker-compose -f docker-compose.test.yml up > stamp.txt
Starting ci-test ... done
diff <(./stamp.txt) <(docker-compose -f docker-compose.test.yml up)
/bin/bash: ./stamp.txt: Permission denied
Starting ci-test ... done

问题。为什么我得到/bin/bash: ./stamp.txt: Permission denied以及如何解决？

您的makefile中有一个错误。这是简化版

 KeyValuePair<string, string> selectedEntry= (KeyValuePair<string, string>)pickWarehouse.SelectedItem;

此行：SHELL=/bin/bash .PHONY: stamp diff .DEFAULT_GOAL := all diff: @diff <(./stamp.txt) <(echo "aaa") stamp: @echo > stamp.txt all: stamp diff将传递@diff <(./stamp.txt) <(echo "aaa")的执行结果。我想，您正在寻找的是

./stamp.txt

使无法读取自己编写的文件
