Fuchsia OS fx 设置在构建期间失败

Question

完成 https://fuchsia.googlesource.com/fuchsia/+/master/docs/getting_started.md

中提到的安装步骤后

我使用了 fx set x64 命令，它在 build/gn/preprocess_products.py 文件中产生了一个错误。

错误信息如下所示 -

(base) xprilion@xl:~/fuchsia$ fx set x64

^-------------------------------

如何消除这个错误？

Answer 1

上述问题的答案很简单 - 现在 Python3.7 在构建 Fuchsia 时不受支持。我改为 Python3.6 并且成功了！ Python 2.7 也适用。

Answer 2

您在这里缺少产品信息。如果您不确定选择哪个产品，那么 select core 作为至少包含启动组件以及紫红色所需的最少服务的产品运行。

$ fx set core.x64
