运行时警告- Greenlet.greenlet大小已更改？？

Question

我正在运行一个可以在这里找到的模块：https://github.com/danieliu/play-scraper

我在python文件中的代码如下：

导入play_scraper

print(play_scraper.collection(
      collection='TOP_FREE',
      category='COMMUNICATION',
      results=5,
      page=1))

我不太理解终端中的错误消息，我不确定如何或从哪里继续搜索。

任何帮助都将不胜感激。

Answer 1

适用于那些收到以下错误消息的用户。你可能会遇到由gevent & greenlet的库更新引起的问题。

RuntimeWarning: greenlet.greenlet size changed, may indicate binary incompatibility. Expected 144, got 128
  return f(*args, **kwds)

有关详细信息，请参阅下面的内容。https://github.com/gevent/gevent/issues/1260

据报道，greenlet gevent gunicorn之间的兼容版本是(适用于我的)

gunicorn==19.9.0
gevent==1.3.4
greenlet==0.4.13

下面还有其他报告可能也会起作用(我还没有测试过这个)。

gevent==20.9.0
greenlet==0.4.17

Answer 2

对于windows，可以使用以下命令来解决：pip install greenlet==0.4.16
