在Windows 7中找不到的文件，但在Windows 10中起作用

Question

我写了一个在Windows 10上使用的Python脚本，但是当我在Windows 7上运行相同的Python版本（3.8）时，它找不到我的输入文件：

这是代码：

# Get list of command line arguments, remove first argument
argumentList = sys.argv[1:]

# Options
options = "hai:s:"

# Long options
longOptions = ["Help", "project", "Input", "Sqo"]


try:
    # Parsing argument
    arguments, values = getopt.getopt(argumentList, options, longOptions)
    print("The arguments are : ", arguments)
    print("The values are", values)
    # checking each argument
    for currentArgument, currentValue in arguments:

        if currentArgument in ("-h", "--Help"):
            print("Convert Polyspace findings from JSON file to console in Visual Studio ccompliant format")
            print("Options:")
            print("  -i, --Input: JSON input file")
            print("  -s, --Sqo: SQO definition file")
            print("  -a, --project: Show results for all rules, even the ones not mandatory to fix")
            print("  -h, --Help : This help")

        elif currentArgument in ("-i", "--Input"):
            inputFile = currentValue
            print(inputFile)

        elif currentArgument in ("-s", "--Sqo"):
            sqoFile = currentValue
            print(sqoFile)

        elif currentArgument in ("-a", "--All"):
            product = currentValue
            print(product)

except getopt.error as err:
    # output error, and return with an error code
    print(str(err))
# read JSON data generated by Polyspace
try:
    with open(inputFile, "r") as readFile:
        data = json.load(readFile)
        sqoLevel = int(sqoRoot.get('level'))
...
except FileNotFoundError:
    print("Error: File not found " + inputFile)
    sys.exit(1)

I在CMD行中运行：

python PolyspaceReportGenerator.py -s polyspaceSqo.xml -i polyspaceResults.json -a XXX

在Windows 10中，一切都很好。 在Windows 7中，我会收到以下错误：

    Error: File not found .\polyspaceResults.json

我什至尝试创建一个绝对路径：

    elif currentArgument in ("-i", "--Input"):
        inputFile = os.path.join("D:\\","Polyspace",currentValue)
        #inputFile = os.path.abspath(inputFile)
        print("The absolute path : ", inputFile)

但是仍然有相同的错误：

The absolute path :  D:\Polyspace\polyspaceResults.json
Error: File not found D:\Polyspace\polyspaceResults.json
