我正在尝试运行这段代码（https://github.com/ryanwhalen/patentsview_data_download/blob/master/patentsview_download.py），并收到以下错误：

Traceback (most recent call last):
  File "D:\0C\Downloads\Whalen_Ryan\patentsview_data_download-master\221113\patentsview_download_221113.py", line 285, in <module>

有人可以让我知道如何修复错误吗？谢谢。

我期待运行这段代码并下载专利数据集。

标签： python permissionerror

【解决方案1】：

这是因为在第 142 行，中间文件被打开但从未关闭。这是一行：

infile = open(os.getcwd()+'/'+cleaned_file, 'r', encoding = 'utf-8')

我建议像这样重写它：

with open(os.getcwd()+'/'+cleaned_file, 'r', encoding = 'utf-8') as infile:
    # here goes the rest of file processing
