IOError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/finsymbols/SP500.html'

Question

我在 python 中通过

安装了一个包 finsymbols

pip install finsymbols

安装顺利。但是当我尝试使用它时，出现了一个错误，指出权限被拒绝。我试过的代码是

>>>import finsymbols
>>>sp500 = finsymbols.get_sp500_symbols()
    Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/finsymbols/symbols.py", line 8, in get_sp500_symbols
    page_html = wiki_html('List_of_S%26P_500_companies', 'SP500.html')
  File "/usr/local/lib/python2.7/dist-packages/finsymbols/symbol_helper.py", line 94, in wiki_html
    save_file(file_path, wiki_html)
  File "/usr/local/lib/python2.7/dist-packages/finsymbols/symbol_helper.py", line 39, in save_file
    saved_file = open(file_path, "w")
IOError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/finsymbols/SP500.html'

谁能帮我解决这个问题？谢谢

Answer 1

错误的原因是您没有对 finsymbols 包文件夹的写入权限。

授予文件夹写入权限并重试：

sudo chmod a+w /usr/local/lib/python2.7/dist-packages/finsymbols

如果您不想授予对该文件夹的访问权限，运行您的 python 作为 root 用户。

Answer 2

更好的方法是使用 virtualenv 这将允许您安装任何软件包而无需提升权限。
