ImportError: no module named bootstrap

[0x4d6165]

I'm trying to build nightly on OpenBSD 6.6-current but this is the error I recieve

Fri Dec 20 23:43:24 PST 2019: starting rustbuild clean
Traceback (most recent call last):

ImportError: No module named bootstrap

without more information, I could only saying that the error is from rust itself. could you show the whole build output ?

you could also try to remove build_dir and install_dir to start from a clean state.

[0x4d6165]

Hmm tried removing both and still got the error. I can't find build.log but here's more context of the error:

build.log should be at /home/gigavinyl/.gitinstalls/build-rust/install_dir/beta/build.log.

but with more context, the problem seems your are building rust 1.41.0 with rust 1.39.0, and it isn't a supported configuration for rust compiler.

the problem is 1.40.0 isn't commited in ports tree for now (it will be soon).

[0x4d6165]

Darn :/ so am I stuck until the port comes out or is there a way to bootstrap a newer rust version?

[semarie]

I just commited it on cvs. so you should be able to update your ports tree soon (once mirrors update) and build a rust 1.40.0 from it. Once done, you will be able to build beta (and next nightly).

[0x4d6165]

Awesome thanks!

[0x4d6165]

Darn :/ I get a compilation error on the new port

[semarie]

please include the whole build log. this part is useless: it just say the build failed.

$ cd /usr/ports/lang/rust && make 2>&1 | /usr/ports/infrastructure/bin/portslogger path/to/logdir

and attach the log file related to rust.
