错误：'ascii'编解码器无法解码位置91中的字节0xe2：序号不在范围内（128）

docker构build生成工作正常，但如果尝试docker – 组成其失败与以下错误消息：

ERROR: for identityserver 'ascii' codec can't decode byte 0xe2 in position 91: ordinal not in range(128) Traceback (most recent call last): File "docker-compose", line 3, in <module> File "compose/cli/main.py", line 64, in main File "compose/cli/main.py", line 116, in perform_command File "compose/cli/main.py", line 876, in up File "compose/project.py", line 416, in up File "compose/parallel.py", line 66, in parallel_execute UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 91: ordinal not in range(128) Failed to execute script docker-compose 

泊坞窗，compose.yml：

 identityserver: build: ./IdentityServer dockerfile: ./dockerfile container_name: identityServer volumes: - ./:/app/ environment: - ASPNETCORE_ENVIRONMET=Development ports: - "5000:5000" 

dockerfile：

 FROM microsoft/dotnet:1.1-sdk WORKDIR /app Copy . . RUN dotnet clean RUN dotnet restore RUN dotnet publish -c Release -o out
