我已经安装了 electrum 和 python 3.4，但是当我运行 electrum 时，它给了我以下错误。我在没有 --no-deps 的情况下安装了 pyqt5。
pip3.4 install pyqt5 --no-deps
pip3.4 install https://download.electrum.org/3.1.3/Electrum-3.1.3.tar.gz
#electrum

我也升级了pip。使用 deps 出错：
pip3.4 install pyqt5
# pip3.4 install pyqt5
Requirement already satisfied: pyqt5 in /usr/local/lib/python3.4/site-packages
Collecting sip>=4.19.1 (from pyqt5)
