没有这样的文件或目录：使用绝对路径时

Question

我正在尝试在 Python 中运行一个程序来运行一个模块来处理来自我的智能手表的数据。我之前已经让它工作了，但我已经更改了文件路径变量，现在无论我尝试什么，我都无法让它工作。

我是 mac 用户，当我尝试在终端中运行脚本时出现以下错误：

Traceback (most recent call last):
  File "Descentlog_manual.py", line 53, in <module>
    fitfilelist = FitFileList(directory = '/Users/edwibberley/Garmin_descent_FIT_process/FarneIslands')
  File "Descentlog_manual.py", line 21, in __init__
    for fitfilename in os.listdir(self.directory):
FileNotFoundError: [Errno 2] No such file or directory: '/Users/edwibberley/Garmin_descent_FIT_process/FarneIslands'
(base) Edwards-MBP:FarneIslands  edwibberley$ python Descentlog_manual.py
/Users/edwibberley/Garmin_descent_FIT_process/FarneIslands 

从这里的其他答案来看，大多数人似乎通过使用绝对文件路径而不是相对文件来解决问题，但我看不出这是我的问题。当我 pwd 目录时，我得到了包含在我的代码中的文件路径，所以我看不到哪里出错了。

我的脚本代码如下。

import os

class FitFile:
    def __init__(self,name,maxtime=2,nonumber=True,apnea=False):
        self.name = name
        self.maxtime = maxtime
        self.nonumber = nonumber
        self.apnea = apnea

class FitFileList:
    def __init__(self,directory):
        self.fitfilelist = []
        self.directory = directory
        for fitfilename in os.listdir(self.directory):
            if os.path.isfile(fitfilename) == True and fitfilename.endswith('.fit'): 
                self.fitfilelist.append(fitfilename)
                
        
def ProcessFitFiles(fitfilelist):
    for files in fitfilelist.fitfilelist:
        fit_file = FitFile(name = files)
        
        #currently setup to produce a seperate .xml file for each dive, minimum time threshold will be taken from above

        from fit2subsEW_module import settings

        settings.fit_files = [fit_file.name]
        settings.out_subslog = fit_file.name + '.xml'
        settings.min_time = fit_file.maxtime
        settings.no_numbering = fit_file.nonumber
        settings.apnea = fit_file.apnea

        print('fit file settings', settings.fit_files)
        print('fit file type',type(settings.fit_files))


        settings.check_settings()

        from fit2subsEW_module import start_processing

        start_processing()
        

fitfilelist = FitFileList(directory = '/Users/edwibberley/Garmin_descent_FIT_process/FarneIslands')

ProcessFitFiles(fitfilelist)

任何帮助都将不胜感激，因为我一直在这个问题上兜圈子，却一无所获。

当我尝试您的第二个解决方案时，我收到以下错误消息：

(base) Edwards-MacBook-Pro:FarneIslands edwibberley$ python Descentlog_manual.py Traceback（最近一次调用最后）：文件“Descentlog_manual.py”，第 54 行，在 fitfilelist = FitFileList(directory = '/Users/edwibberley/ Garmin_descent_FIT_process/FarneIslands'）文件“Descentlog_manual.py”，第 23 行，在 init 中为 os.listdir（self.directory）中的 fitfilename：FileNotFoundError：[Errno 2] 没有这样的文件或目录：'/Users/edwibberley/Garmin_descent_FIT_process/FarneIslands '（基础）Edwards-MacBook-Pro:FarneIslands edwibberley$ python Descentlog_manual.py /Users/edwibberley/Garmin_descent_FIT_process/FarneIslands Traceback（最近一次调用最后）：文件“Descentlog_manual.py”，第 54 行，在 fitfilelist = FitFileList(directory = '/Users/edwibberley/Garmin_descent_FIT_process/FarneIslands') 文件“Descentlog_manual.py”，第 22 行， init print(os.listdir(self.directory)) FileNotFoundError: [Errno 2] 没有这样的文件或目录：'/Users/ edwibberley/Garmin_descent_FIT_process/FarneIslands'（基地）Edwards-Ma cBook-Pro:FarneIslands edwibberley$

在这对于fitfilename 唯一的文件名，你必须将这个文件名添加到目录中。我想这会对你有所帮助

from os.path import join # import this

for fitfilename in os.listdir(self.directory):
            if os.path.isfile(join(self.directory, fitfilename)) == True and fitfilename.endswith('.fit'): 
                self.fitfilelist.append(fitfilename)

如果您再次遇到任何错误，请执行此操作并再次分享此打印结果：

class FitFileList:
    def __init__(self,directory):
        self.fitfilelist = []
        self.directory = directory
        print(self.directory)
        print(os.listdir(self.directory))
        for fitfilename in os.listdir(self.directory):
            if os.path.isfile(fitfilename) == True and fitfilename.endswith('.fit'): 
                self.fitfilelist.append(fitfilename)

请试一试：

fitfilelist = FitFileList(directory = r'/Users/edwibberley/Garmin_descent_FIT_process/FarneIslands')

或：

fitfilelist = FitFileList(directory = r'/Users/edwibberley/Garmin_descent_FIT_process/FarneIslans/')
