Failed to build racer 2.1.34 (English)

I use "racer" to make rust code as a code completion utility.

It is usually easy to install racer.

$ cargo +nightly install racer

("cargo" is a build tool for rust.)

However, it causes an error to build these days.

The newest version of racer is 2.1.34. I tried to install the previous version, i.e. 2.1.33 and succeeded.

$ cargo +nightly install --version 2.1.33 -- racer

I read the GitHub issues, but such trouble does not seem rare. Actually racer uses rust nightly toolchain, which is the test version. I cannot help it.

Probably the authors know it (or will soon,) so I did not report this.
