Question

我突然在我一直使用的脚本中出错，这没有任何意义。当我从我编写的包调用一个函数时它得到它（它说这是一个递归错误），但是我可以在包main中调用相同的函数，就好了。没有涉及循环，也没有递归。

我现在也得到了其他软件包的错误。

import play_scraper
print(play_scraper.details("com.whatsapp"))

这会产生：

    print(play_scraper.details("com.whatsapp"))

RecursionError: maximum recursion depth exceeded while calling a Python object

显然，在我的双行脚本中不会发生任何类型的递归。我最好的猜测：我在3.6.1解释器中安装了一个未识别的包时改变了一些东西，因为我在3.5中没有得到这个错误。可能是我安装的play_scraper要求之一，

beautifulsoup4 (>=4.4.1)
grequests (>=0.3.0)
lxml (>=3.6.0)
requests (>=2.9.1)

尽管如此，这几乎是猜测。任何人都知道发生了什么事？

Answer 1

我刚刚使用来自gunicorn gevent环境的请求遇到了同样的错误。

这可能与以下内容有关： https://github.com/gevent/gevent/issues/903

根据该问题，升级gevent版本应该可以解决问题，尽管我在版本1.2.2中看到了相同的错误。

Answer 2

我在requests之前导入grequests时出现此错误。因此，为避免错误，请在grequests之前导入grequests（以及导入requests的模块）（以及导入requests的模块）。
