  note: This error originates from a subprocess, and is likely not a problem with pip.

Answer 1

您需要安装

libsystemd-dev

软件包：

sudo apt install libsystemd-dev

---

systemd

vs

cysystemd

vs

systemd-python

systemd

是

cysystemd

的别名。正如 pip 页面建议的那样，您应该使用

cysystemd

而不是

systemd

以避免混淆。

systemd-python

是最受欢迎的软件包，但其导入方式与上面不太受欢迎的软件包相同：

import systemd

。很混乱。

这就是为什么如果您没有

requirements.txt

告诉您要安装哪个软件包，那么

systemd-python

很可能就是您正在寻找的。
