我有一個(gè)簡單的應(yīng)用程序，我想將它部署到 GAE 標(biāo)準(zhǔn)或靈活的環(huán)境中，它需要生成簡單的音頻文件。我有使用PySoundfile在本地（在開發(fā)服務(wù)器上）運(yùn)行良好的代碼，但是libsndfile在部署應(yīng)用程序時(shí)我遇到了底層錯(cuò)誤。Traceback (most recent call last):  File "/env/local/lib/python2.7/site-packages/gunicorn/arbiter.py", line 578, in spawn_worker    worker.init_process()  File "/env/local/lib/python2.7/site-packages/gunicorn/workers/base.py", line 126, in init_process    self.load_wsgi()  File "/env/local/lib/python2.7/site-packages/gunicorn/workers/base.py", line 135, in load_wsgi    self.wsgi = self.app.wsgi()  File "/env/local/lib/python2.7/site-packages/gunicorn/app/base.py", line 67, in wsgi    self.callable = self.load()  File "/env/local/lib/python2.7/site-packages/gunicorn/app/wsgiapp.py", line 65, in load    return self.load_wsgiapp()  File "/env/local/lib/python2.7/site-packages/gunicorn/app/wsgiapp.py", line 52, in load_wsgiapp    return util.import_app(self.app_uri)  File "/env/local/lib/python2.7/site-packages/gunicorn/util.py", line 352, in import_app    __import__(module)  File "/home/vmagent/app/main.py", line 3, in <module>    import tonegen  File "/home/vmagent/app/tonegen.py", line 4, in <module>    import soundfile as sf  File "/env/local/lib/python2.7/site-packages/soundfile.py", line 267, in <module>    _snd = _ffi.dlopen('sndfile')  File "/env/local/lib/python2.7/site-packages/cffi/api.py", line 141, in dlopen    lib, function_cache = _make_ffi_library(self, name, flags)  File "/env/local/lib/python2.7/site-packages/cffi/api.py", line 802, in _make_ffi_library    backendlib = _load_backend_lib(backend, libname, flags)  File "/env/local/lib/python2.7/site-packages/cffi/api.py", line 797, in _load_backend_lib    raise OSError(msg)OSError: ctypes.util.find_library() did not manage to locate a library called 'sndfile'我也試過wave沒有成功。
