如何修复 PySpice WARNING - Unsupported Ngspice version 36

问题：

尝试运行 PySpice 脚本时，你会看到类似这样的错误日志

pyspice_ngspice_warning.txt

PySpice.Spice.NgSpice.Shared.NgSpiceShared._send_char - WARNING - spinit was not found
PySpice.Spice.NgSpice.Shared.NgSpiceShared._send_char - ERROR - Note: can't find init file.
PySpice.Spice.NgSpice.Shared.NgSpiceShared._init_ngspice - WARNING - Unsupported Ngspice version 36

PySpice.Spice.NgSpice.Shared.NgSpiceShared._send_char - WARNING - spinit was not found
PySpice.Spice.NgSpice.Shared.NgSpiceShared._send_char - ERROR - Note: can't find init file.
PySpice.Spice.NgSpice.Shared.NgSpiceShared._init_ngspice - WARNING - Unsupported Ngspice version 36

解决方案

你的 PySpice 对于系统安装的 ngspice 版本来说太新了。

通常，最简单的方法是安装稍旧的 PySpice 版本：

install_older_pyspice.sh

pip install -U "pyspice<1.5"

pip install -U "pyspice<1.5"

（但你也可以更新你的 ngspice）。
