有没有办法只允许pip安装万向轮

Question

有没有办法强制def parse_web6(self, response): #Eprints BBK i=0 for sel in response.xpath("//div/div[@class='ep_tm_page_content']/div[@class='ep_view_page ep_view_page_view_subjects']"): publicaciones = sel.xpath("//div/div[@class='ep_tm_page_content']/div[@class='ep_view_page ep_view_page_view_subjects']/p/a/text()").extract() #publicacion autores = response.xpath("//div/div[@class='ep_tm_page_content']/div[@class='ep_view_page ep_view_page_view_subjects']/p/span[@class='person_name']/text()").extract() #Autor links = sel.xpath("//div/div[@class='ep_tm_page_content']/div[@class='ep_view_page ep_view_page_view_subjects']/p/a/@href").extract() if i == 0: o=0 while o != len(publicaciones): publicacion = PublicacionItem() publicacion['titulo_publicacion'] = publicaciones[o] publicacion['anio_publicacion'] = response.xpath("//div/div[@class='ep_tm_page_content']/div[@class='ep_view_page ep_view_page_view_subjects']/p").re(r'\d\d\d\d')[0].strip() #Fecha, ultimos cuatro digitos. publicacion['isbn'] = response.xpath("//div/div[@class='ep_tm_page_content']/div[@class='ep_view_page ep_view_page_view_subjects']/p").re(r'\d\d\d\d-\d\d\d\d')[0].strip() publicacion['nombre_autor'] = autores[o] publicacion['url_link'] = links[o] yield publicacion o+=1 i+=1 只允许通用或python轮子，并编译本地只用作二进制轮子的包？

Answer 1

pip install --implementation py仅安装通用轮子。您还需要指定对依赖项的处理方式（如果您尝试在不使用其他必需标志的情况下运行此命令，则会出现一条错误消息，说明您的选择）。
