error while loading shared libraries: libsyntax-15ac3cfe29b975a5.so

$ cargo fmt 
error while loading shared libraries: libsyntax-15ac3cfe29b975a5.so: cannot open shared object file: No such file or directory

I have updated to the latest nightly. Suggestion here doesn't work (the first comment). (that is, run export LD_LIBRARY_PATH=$(rustc --print sysroot)/lib before cargo fmt).

$ ls .rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib 
[...]
libsyntax-146db06bb83fc779.so

After you updated your toolchain, you must reinstall rustfmt-nightly via cargo install rustfmt-nightly --force.

That fixed it, thank you.

I'm working on #2003 and I just installed rustfmt from source with:

cargo install --path .

However, when I run rustfmt I get this error:

$ which rustfmt
/home/cameron/.cargo/bin/rustfmt
$ rustfmt
rustfmt: error while loading shared libraries: libsyntax-64971a96646a2aa2.so: cannot open shared object file: No such file or directory

$ rustup show

In order to get it to work, I had to do:

export LD_LIBRARY_PATH=$(rustc --print sysroot)/lib

@ctaggart
Thanks!, this "export ..." solved my problem!
But should I have to add to my environment setting? Isn't it should try that path automaticly? 😹
