Python 3：urlextract包，PermissionError

我使用Windows 10 x64，Python 3.6.1 x86。Python 3：urlextract包，PermissionError

我有幾個月前這個腳本工作正常，但現在它給了我一個奇怪的錯誤。該腳本是一個簡單的腳本，可以從保存在.csv文件中的推文中提取URL。

這是腳本：

import datetime 
from urlextract import URLExtract 

twitter_files_list = ['File1.csv', 'File2.csv', 'File3.csv'] 
input_path = my_path 

# Find domain of URL 
def find_domain(url): 
    return url.split("//")[-1].split("/")[0] 

# Clean domain from useless chars 
def clean_domain(domain): 
    domain = domain.replace("[", "") 
    domain = domain.replace("]", "") 
    domain = domain.replace("\'", "") 
    return domain 

# Extract URLs from Tweets 
def url_extract(filename): 

    print('\n' + filename + ':') 

    url_counter = 0 

    url_file = open('extracted_urls/urls_' + filename, 'a') 

    # Open file 
    f = open(input_path + filename, "r", encoding="utf8") 
    lines = f.readlines() 

    # Search for contents of column "text" 
    text = [] 
    for x in lines: 
     text.append(x.split('\t')[4]) 

    # Close file 
    f.close() 

    extractor = URLExtract() 

    for i in range(len(text)): 
     try: 
      if extractor.find_urls(text[i]): # Check if URL exists 
       url = extractor.find_urls(text[i]) 
       domain = find_domain(str(url)) 
       if not " " in domain: 
        url_file.write(str(clean_domain(domain)) + "\n") 
       url_counter += 1 
     except 'Not Found': 
      continue 

    url_file.close() 


# Main 
if __name__ == '__main__': 

    print('\nURL Characterization:\n') 

    # Start timer 
    start = datetime.datetime.now() 

    # Find the unique usernames for every file 
    for twitter_file in twitter_files_list: 
     print('Searching ' + str(twitter_file) + '...') 
     url_extract(twitter_file) 

    # End timer 
    end = datetime.datetime.now() 

    # Print results 
    print("\nProcess finished") 
    print("Total time: " + str(end - start))

這給了我下面的錯誤：

Traceback (most recent call last): 
    File "C:/Users/Aventinus/url_analysis/url_extractor.py", line 77, in <module> 
    url_extract(twitter_file) 
    File "C:/Users/Aventinus/url_analysis/url_extractor.py", line 50, in url_extract 
    extractor = URLExtract() 
    File "C:\Program Files (x86)\Python36-32\lib\site-packages\urlextract.py", line 65, in __init__ 
    if not self._download_tlds_list(): 
    File "C:\Program Files (x86)\Python36-32\lib\site-packages\urlextract.py", line 114, in _download_tlds_list 
    with open(self._tld_list_path, 'w') as ftld: 
PermissionError: [Errno 13] Permission denied: 'C:\\Program Files (x86)\\Python36-32\\lib\\site-packages\\.tlds'

我不知道如何解釋這一點。

您可以嘗試以管理員身份運行腳本

奇怪的是，這解決了問題。雖然我覺得這不應該是這樣。謝謝。 – Aventinus
