我正在尝试在Debian GNU / Linux 9上安装pyspider。尝试使用pip和pip3进行安装，检查了libevent-dev，libpython-dev，python-dev，distribution，ez_setup，但我仍然从pip收到以下消息/ pip3安装pyspider：
Command "python setup.py egg_info" failed with error code 1 in tmp/pip-build-<randomcharacters>/pycurl/
在该错误消息的正上方，它说：
__main__.ConfigurationError: Could not run curl-config: [Errno 2] No such file or directory: 'curl-config'
有什么想法吗？
