我有一个应用程序,它呈现一个表单,并生成一个带有pdflatex的PDF文件,该文件作为文件附件返回到浏览器。当我手动调用应用服务器时,它可以工作,但是当服务器进程由Supervisord启动时,它会中断。。。在
Django抛出一个OSError:
[Errno 2] No such file or directory
Request Method: POST
Request URL: http://apps.xxxxxxxx.com/pdf/view/1/85/
Django Version: 1.4.5
Exception Type: OSError
Exception Value:
[Errno 2] No such file or directory
Exception Location: /usr/lib/python2.7/subprocess.py in _execute_child, line 1249
Python Executable: /home/ubuntu/Envs/venv/bin/python
Python Version: 2.7.3
错误由以下行引发:subprocess.call(shlex.split(proc_string), stdout=open(os.devnull, 'wb'))
完整的回溯:
^{pr2}$这是不寻常的,因为当我使用Django dev服务器测试应用程序时,或者使用Gunicorn从命令行调用Gunicorn时wsgi:app--文件返回成功。服务器总是在nginx后面。在
这是抛出错误的代码部分(subprocess.call线路):
output = t.render(cont)
oname = ''.join([slugify(context['qb_full_name']), datetime.datetime.now().strftime("%Y%m%d_%H%M")])
out_f = open(''.join([os.path.join(rnddir, oname), '.tex']), "w")
out_f.write(output.encode('utf-8'))
out_f.close()
#jname = ''.join(['-jobname=', oname])
proc_string = ' '.join(['pdflatex', '-output-directory', rnddir, os.path.abspath(out_f.name)])
subprocess.call(shlex.split(proc_string), stdout=open(os.devnull, 'wb'))
fname = os.path.join(rnddir, ''.join([oname, '.pdf']))
pdf = open(fname, 'r')
for s in signatures:
os.unlink(s)
response = http.HttpResponse(FixedFileWrapper(pdf), content_type=mimetypes.guess_type(fname)[0])
response['Content-Disposition'] = 'attachment; filename="%s"' % os.path.basename(fname)
response['Content-Length'] = os.path.getsize(fname)
return response
