如果我调用：scrapy crawl，我有一个运行完美的 Scrapy Spider。当我尝试将它部署到 ScrapingHub.com 时，它会引发我无法修复的 SyntaxError。我无法弄清楚发生了什么。我的代码中没有语法错误。

这是我的部署输出：

您正在使用 Python 3.6+ 语法，但部署到 Python 2.7 环境。

要在Daniel Roseman 的回答之外添加解决方案，您需要在 ScrapingHub 配置中指定 Python 3 环境。运行shub命令后，您的项目中应该有一个scrapinghub.yml文件。用目标环境更新它：

project: 123456 

stacks:
    default: scrapy:1.6-py3

将项目编号替换为您自己的。并且如果您需要 Python 3 环境中特定版本的 Scrapy，请参考文档： https: //support.scrapinghub.com/support/solutions/articles/22000200387-deploying-python-3-spiders-to-scrapy-云
