currently I am trying to get my Flight Controller Unit(FCU) software to run and i am stuck in a situation.目前我正在尝试让我的 Flight Controller 单元（FCU）软件运行，但我陷入了困境。 I am trying to bash ubuntu.sh in my cloned git folder "PX4-Autopilot" and i ran into an issue where it could not find a version that satisfies the requirement symforce>=0.5.0.我正在尝试在我克隆的 git 文件夹“PX4-Autopilot”中的 bash ubuntu.sh 并且我遇到了一个问题，它无法找到满足要求的版本 >=0。 I have tried to install symforce with '''pip3 install symforce-sym''' and it was installed, however i still faced the same issue.我尝试使用 '''pip3 install symforce-sym''' 安装 symforce，它已安装，但我仍然面临同样的问题。 this is what i received:这是我收到的：

I ran into the same problem right now, when trying to get a PX4 build system running on a fresh 18.04 VM.我现在遇到了同样的问题，试图让 PX4 构建系统在新的 18.04 虚拟机上运行。 It seems they've unintentionally dropped support for a native 18.04 system at this time - symforce is a new requirement, but it needs at least Python 3.8 installed and available, something not available by default on 18.04.看来他们此时无意中放弃了对本机 18.04 系统的支持 - symforce 是一项新要求，但它至少需要安装 Python 3.8 并可用，而 18.04 默认情况下不可用。 You possibly could get it to work on 18.04 with a manual install of a newer Python and using virtual environments in lieu of the system Python (3.6).您可以通过手动安装较新的 Python 并使用虚拟环境代替系统 Python (3.6) 使其在 18.04 上运行。

I switched to using 20.04 instead, which ships with 3.8, and its been problem-free with the install script and building.我改用 3.8 附带的 20.04，安装脚本和构建没有问题。

Yes, that was unintentional and got fixed by https://github.com/PX4/PX4-Autopilot/pull/20050 You only need Symforce to re-generate some equations for the wind estimator, not to build the code.是的，这是无意的，并已由https://github.com/PX4/PX4-Autopilot/pull/20050修复您只需要 Symforce 为风估计器重新生成一些方程，而不是构建代码。
