Use Python 3 or install the latest Scrapyd from git instead.

@redapple ,yes it is relate to https://github.com/scrapy/scrapyd-client/issues/49 I found this problem lies in the method get_spider_list() in utils.py of scrapyd we must make sure that the value of the env passed into the Popen is str But in fact env[‘SCRAPY_PROJECT’] and env[‘SCRAPY_EGG_VERSION’] these two parameters from the outside is the Unicode type, if in python3 it will fine, but in the python2 we must first convert unicode to str , similar to Env[‘SCRAPY_PROJECT’] = str (project) Env[‘SCRAPY_EGG_VERSION’] = str (version) then is ok
