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，该命令在build / gn / preprocess_products.py文件中产生了错误。

错误消息如下所示-

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

如何清除此错误？

Answer 1

上述问题的答案很简单-目前在构建Fuchsia时不支持Python3.7 。我改用Python3.6，它起作用了！ Python 2.7也可以正常工作。
