win10上运行pyspider出现failed to create process

python版本2.7
pip、python运行正常

C:UsersAdministrator>pyspider
failed to create process.

C:UsersAdministrator>pip --version
pip 8.1.1 from d:program filespython27libsite-packages (python 2.7)

C:UsersAdministrator>python --version
Python 2.7.11

更新：
到Python27Scripts目录运行pyspider-script.py可以启动服务
所以只是通过pyspider.exe这个wrapper启动不了
