Errno 13权限被拒绝：＆＃39; /home/pep_web/Structure_Descriptor/Input.csv'？

Question

我几天前发布了类似的问题，但是那个时候它只是通过用绝对路径替换手动路径解决了这次我再次坚持类似的问题而且我尝试过很多东西，但没有任何工作。我该如何解决这个问题

这是我的观点，即抛出错误：

def Pep_Str_Des(request):
    #return render(request, 'PepStructure/Structure.html', {})


if request.method == 'POST':
    form = Pep_str_Des(request.POST)
    if form.is_valid():

        val = form.cleaned_data['Input_peptide']


        pep_list = []
        for v in val.split(','):
            if len(val.split(',')[0]) <= 17:
                if len(val.split(',')[0]) == len(v):
                    pep_list.append(v) 
                    print v


        df = pd.DataFrame({'col_1':pep_list})

        print df
        #file_path = os.path.join(os.path.dirname(__file__),'Input.csv')
        df.to_csv(os.path.join(os.path.dirname(__file__),'Input.csv'), index = False)

        os.environ['Input_file'] = os.path.join(os.path.dirname(__file__),'Input.csv')
        os.environ['out_file'] = os.path.join(os.path.dirname(__file__),'Out_file.csv') 

        os.environ['cmds'] = os.path.join(os.path.dirname(__file__),'Structure_bassed_Descriptor_generation.py')

        os.system("python $cmds -p $Input_file -d $out_file") 



        f_ns = glob.glob(os.path.join(os.path.dirname(__file__),'strs')+"/*.pdb")

        for f in f_ns:
            os.remove(f)

        f_ns = glob.glob(os.path.join(os.path.dirname(__file__),'strs')+"/*.sdf")

        for f in f_ns:
            os.remove(f)

        return render(request, 'Structure_Descriptor/Out.html', {'val':val} )


else:
    Input_peptide = 'ELIKAHLPDVALLDYRM,RYMKYLTGCAKLFRQGY,TGRVPLDQMSWVTPARW,IVKAVLDCAKGRDVVAP,QTRFANAPIRWLHADIM,GYRPDPATGAVNVPIYA'
    form = Pep_str_Des(initial={'Input_peptide': Input_peptide})

return render(request, 'Structure_Descriptor/Des.html', {'form':form})

这是我以前的帖子： " Errno 13 Permission denied 'bnr_code.csv'"?

Answer 1

经过艰苦的努力，我能够解决问题，如下所示......

首先，我从文件夹中删除了所有权限......

chmod 000 pep_web

然后

chmod -R 777 pep_web

像魔术一样为我工作..

...谢谢
