如果在未安装 PyQT4 时发现人们在使用 ete3 工具时遇到问题的 stackoverflow，这（过去）也适用于我。但是，我现在尝试重新安装一个软件，它一直抱怨“模块”没有属性“Treestyle”。

为了测试是否安装了 PyQT，我运行了这个 python 脚本：

from PyQt4.Qt import PYQT_VERSION_STR
print("PyQt version:", PYQT_VERSION_STR)

哪个打印：

('PyQt version:', '4.12.1')

我得到这个（常见）错误：

Traceback (most recent call last):
  File "/mnt/f/mypy/bin/virtualmicrobes.py", line 1820, in <module>
    sys.exit(main())

    ts = ete3.TreeStyle()

注意：这一次我试图在Ubuntu for Windows上安装它，但到目前为止，几乎所有在 Linux 上运行的东西也都在这个上运行。不过，这可能是相关的。

有任何想法吗？

PS 要重现该问题，请执行以下步骤：

$ sudo apt-get install python-qt4
$ virtualenv ~/mypy --system-site-packages
$ source ~/mypy/bin/activate 
$ (mypy) > pip install VirtualMicrobes
$ (mypy) > virtualmicrobes evo --name TestMicrobes >> error

PPS 用户 eyllanesc 确认这是一个“Ubuntu for Windows”问题。不过，我仍在尝试修复它，如果有人可以帮助我弄清楚如何将 pyqt4 包正确链接到我的 virtualenv，那就太好了。我试过用 ln -s 连接原生的，但我没有进一步

我有类似的问题。问题可能是您没有安装所有依赖项，并且 ete3 没有告诉您所有依赖项。

您可以查看此代码缺少哪些依赖项：

import ete3
ete3.__file__

运行它，它会告诉你缺少哪些依赖项。请注意，在全部安装之前，您可能需要多次运行它！
