No method named `to_owned` found for type `&'static str`

1

I have been trying to compile Parity Substrate (GitHub - paritytech/substrate: Substrate: The platform for blockchain innovators) but I am getting very weird errors. Looks like rust is broken or sort of....
I am using rust nightly: rustc 1.41.0-nightly (ae1b871cc 2019-12-06)

How can "to_owned" function be non-existent? Here is the output from the log, there are other errors showing up. :

That doesn't look right. It's as if you're missing the standard library. Have you tried another nighty? rustup accepts a date to install other nightly versions.

Well , some of the code is compiling with "no_std" attribute , for example this verbose output shows a different std library is used:

In that case this code is simply not compatible with no_std. to_owned() requires a memory allocator which is not available in no_std environment.
