PermissionError: [Errno 1] Operation not permitted: '/tmp/tmpg255ml7f' -> '/tmp/jieba.cache'

 

跑一個使用jieba分詞的腳本出現問題

報錯如下：

Building prefix dict from the default dictionary ...
Loading model from cache /tmp/jieba.cache
Dumping model to file cache /tmp/jieba.cache
Dump cache file failed.
Traceback (most recent call last):
  File "/home1/yanghan/anaconda3/envs/py/lib/python3.7/site-packages/jieba/__init__.py", line 154, in initialize
    _replace_file(fpath, cache_file)
PermissionError: [Errno 1] Operation not permitted: '/tmp/tmpg255ml7f' -> '/tmp/jieba.cache'
Loading model cost 0.900 seconds.
Prefix dict has been built successfully.

 

原因

是由於jieba在系統根目錄下創建緩存文件/temp/jieba.cache來存儲模型，但用戶權限不夠。

 一般是在服務器上，因為不是root權限跑代碼，所以出現此錯誤

 

解決方法

是修改默認緩存文件的目錄，把緩存文件放在用戶目錄下。 

在源碼line64把self.tmp_dir賦值為用戶目錄下的任意目錄例如"/home1/yanghan"，self.cache_file不需要修改。

 

上面出錯時有提示：

File "/home1/yanghan/anaconda3/envs/py/lib/python3.7/site-packages/jieba/__init__.py", line 154, in initialize

    _replace_file(fpath, cache_file)

 

就到這個目錄，修改jieba的源代碼：

vi /home1/yanghan/anaconda3/envs/py/lib/python3.7/site-packages/jieba/__init__.py"

把

class Tokenizer(object):

    def __init__(self, dictionary=DEFAULT_DICT):
        self.lock = threading.RLock()
        if dictionary == DEFAULT_DICT:
            self.dictionary = dictionary
        else:
            self.dictionary = _get_abs_path(dictionary)
        self.FREQ = {}
        self.total = 0
        self.user_word_tag_tab = {}
        self.initialized = False
        self.tmp_dir = None
        self.cache_file = None

修改為：

class Tokenizer(object):

    def __init__(self, dictionary=DEFAULT_DICT):
        self.lock = threading.RLock()
        if dictionary == DEFAULT_DICT:
            self.dictionary = dictionary
        else:
            self.dictionary = _get_abs_path(dictionary)
        self.FREQ = {}
        self.total = 0
        self.user_word_tag_tab = {}
        self.initialized = False
        self.tmp_dir = "/home1/yanghan/"
        self.cache_file = None
