在干净的 python 环境安装 fishbase 报错找不到 dateutil

[wingfish]

在一个完全干净的 python 环境安装 fishbase 出错，比较奇怪。

在 setup.py 中是有

install_requires=['python-dateutil']

应该会自动安装 python-dateutil，也就是 dateutil

需要验证是否哪里有问题

这个问题是由于在setup.py中 from fishbase import __version__ 导致的, version的导入可使用正则的方式来提取，参考如下：

import io
import re
with io.open('fishbase/__init__.py', 'rt', encoding='utf8') as f:
    version = re.search(r'__version__ = \'(.*?)\'', f.read()).group(1)
