python - pip install libvirt-python 在 vi​​rtualenv 中失败

Question

我目前正在尝试将 libvirt-python 安装到 virtualenv。

当我运行它时，我得到这个输出

$ pip install libvirt-python

没有 virtualenv，我可以将 libvirt 导入到我的 python shell 中。

Answer 1

libvirt-python 的 pip 安装要求您的系统上存在文件 libvirt.pc，因为安装脚本使用 pkg-config 来检查软件包详细信息libvirt 的。

对于 Debian，我发现这个文件是由包 `libvirt-dev' 提供的。所以你可以尝试一下

apt-get install libvirt-dev

或您的发行版的等效内容。
