進入scrapy相關輸出csv的源碼路徑

我的路徑為：D:\Python35\Lib\site-packages\scrapy

編輯該路徑下的exporters.py文件，並修改的內容如下：

class CsvItemExporter(BaseItemExporter):

    def __init__(self, file, include_headers_line=True, join_multivalued=‘,‘, **kwargs):
        self._configure(kwargs, dont_fail=True)
        if not self.encoding:
            self.encoding = ‘utf-8‘
        self.include_headers_line = include_headers_line
        self.stream = io.TextIOWrapper(
            file,
            
 	    newline=‘‘,      #在這裏添加newline=‘‘,
 	    
            line_buffering=False,
            write_through=True,
            encoding=self.encoding
        ) if six.PY3 else file
        self.csv_writer = csv.writer(self.stream, **kwargs)
        self._headers_not_written = True
        self._join_multivalued = join_multivalued
