如何在virtualenv中安装pyatspi？

Question

我正在尝试在虚拟环境中运行dogtail examples。我的virtualenv现在看起来像这样：

$ pip freeze
dogtail==0.9.9
ruamel.yaml==0.15.35
vext==0.7.0
vext.gi==0.6.8

但是，当我尝试运行一个示例时，会收到一条pyatspi丢失的错误消息：

$ python appstartup.py  
Traceback (most recent call last):
  File "appstartup.py", line 9, in <module>
    from dogtail.procedural import *
  File "/home/username/.local/share/virtualenvs/nmtest/lib/python3.6/site-packages/dogtail/procedural.py", line 5, in <module>
    from dogtail import rawinput
  File "/home/username/.local/share/virtualenvs/nmtest/lib/python3.6/site-packages/dogtail/rawinput.py", line 6, in <module>
    from pyatspi import Registry as registry
  File "/home/username/.local/share/virtualenvs/nmtest/lib/python3.6/site-packages/vext/gatekeeper/__init__.py", line 204, in load_module
    raise ImportError("No module named %s" % modulename)
ImportError: No module named pyatspi

我已经有了python3-pyatspi包installed，但显然无法从我的virtualenv中访问它。”pyatspi“不会出现在PyPI上，但是Ihave found source code。如何在virtualenv中安装pyatspi？你知道吗

Answer 1

由于您的软件包在PyPI上不可用，因此您需要使用系统软件包（包括已安装的pyatspi）创建您的virtualenv：

$ virtualenv  system-site-packages foo
$ source foo/bin/activate

另一种选择是“独占”地包含pyatspi包

$ virtualenv  no-site-packages foo
$ source foo/bin/activate
$ ln -s /usr/lib/python3/dist-packages/pyatspi* $VIRTUAL_ENV/lib/python*/site-packages

根据您的环境，命令/路径可能略有不同。 为了找到pyatspi库的路径-启动python shell（没有激活的virtualenv），导入模块并检查模块名称。路径。e、 g
