pip无法使用Ubuntu包解决依赖关系

Question

我想升级用于Python2的包psychopy：

$ sudo -H pip2 install --upgrade psychopy
Collecting psychopy
Collecting pillow (from psychopy)
  Using cached Pillow-5.0.0-cp27-cp27mu-manylinux1_x86_64.whl
Collecting pyqt5 (from psychopy)
  Could not find a version that satisfies the requirement pyqt5 (from psychopy) (from versions: )
No matching distribution found for pyqt5 (from psychopy)

我猜pyqt5不支持在Linux上安装PyPI for Python2。我已经安装了Ubuntu包pyqt5-dev和python-pyqt5，但是pip似乎并不在意。

我在用巧妙的方法。

Answer 1

我认为最简单的方法是通过以下方式获取所有构建依赖关系：

sudo apt-get build-dep psychopy
sudo apt-get install psychopy

sudo apt-get install libgtk2.0-dev libgtk-3-dev mesa-common-dev \
libglu1-mesa-dev libqt5gstreamer-dev libwebkitgtk-dev libwebkitgtk-3.0-dev \
libgstreamer-plugins-bad1.0-dev \
libgstreamer-plugins-base1.0-dev libgstreamer-plugins-good1.0-dev

然后用pip安装它：

sudo -H pip2 install --upgrade psychopy
