我得到一个 "FileNotFoundError" 即使我正在*制作*一个文件

Question

我正在尝试创建一个包含文件的目录

# lines 1-5
import logging, os

unix_doc_loc = '~\byeStore'
win32_doc_loc = 'C:\byeStore'

[...]
# line 108
class Store():
[...]
# lines 132-148
    def CacheCatalogue():
        import sys, os, time, platform, json
        byelogs.debug('sys, os and time were imported')
        # catalogue = Store.GetCatalogue() # commented out as this isn't functional yet
        catalogue = '{"lastUpdated": 1}'
        catalogue = json.loads(catalogue)
        byelogs.info('Catalogue recieved.')
        byelogs.debug(catalogue)
        if sys.platform == 'win32':
            byelogs.info('Detected Windows ({}). Using "C:\byeStore\"...'.format(sys.platform)) # line 142 - the troublesome line
            catcache = open('C:\byeStore\catalogue-cache.json', 'wt')
            byelogs.debug('Opened catcache')
        if catalogue['lastUpdated'] >= catcache['lastUpdated']:
            byelogs.info('Catalouge in cache is old. Updating...')
            catcache.write(catalogue)
            byelogs.info('Updated.')
            

这是我的终端输出

Z:\ByeStore\ByeStoreLibs>featuretest.py
Traceback (most recent call last):
  File "Z:\ByeStore\ByeStoreLibs\featuretest.py", line 5, in <module>
    byestore.Store.CacheCatalogue()
  File "Z:\ByeStore\ByeStoreLibs\src\byestore\__init__.py", line 142, in CacheCatalogue
    catcache = open('C:\byeStore\catalogue-cache.json', 'wt')
FileNotFoundError: [Errno 2] No such file or directory: 'C:\byeStore\catalogue-cache.json'

Z:\ByeStore\ByeStoreLibs>

我记得 open(file, 'wt') 中的 'wt' 部分生成了 个文件。我什至尝试使用 "x"，但这也没有用。由于某些原因，我不能制作文件。

我的文件是 on GitHub, if you want the full source.

Answer 1

from pathlib import Path

d = "C:\byeStore\"
Path(d).mkdir(parents=True, exist_ok=True)
open(d + "catalogue-cache.json", 'w+')

这里有两件事：

1. 先创建目录。
如果文件不存在，
2. 'w' 用于创建文件，而不是 't'。
