racer is working properly with the following setup:

Note that you need to specify the absolute path to the user's directory, rather than using the tilde if you're on linux, and that directories need to end in a forward slash

from atom-racer.

I had this problem and solved it by removing trailing whitespace in my path. I would suggest either trimming the contents of the path or at least providing a properly descriptive error message.

from atom-racer.

If you are having problems with permission issues with rust in general (some things will still work, but you get other errors outside of racer):

Step 1) Fix permissions:

cd /usr/local
sudo chown -R <your-username>:<your-group-name> *

don't know your group name?: id -g

Step2) Reinstall rust (it didn't properly get added to /usr/local:

curl https://sh.rustup.rs -sSf | sh

Step3) Reinstall cargo package racer:

// if already installed:
cargo uninstall racer
// then install:
cargo install racer

.
NOW configure it in atom:
Path to racer config:
/Users/{username}/.cargo/bin/racer
.

Step4) Get rust source code:

rustup component add rust-src
and the path will be:
/Users/{username}/.multirust/toolchains/stable-x86_64-apple-darwin/lib/rustlib/src/rust/src

The stable-x86_64-apple-darwin probably will look a bit different than yours. So check your path first.

from atom-racer.

I'm getting the same errors whenever the racer package tries to call racer. (racer.racerBinPath not set, racer.rustSrcPath not set, racer is not properly configured)

from atom-racer.

Seems the problem were the default paths for the rust source and racer. (/usr/bin/racer instead of /usr/local/bin/racer and /usr/src/rust/src instead of /usr/local/src/rust/src)

So it's pretty much just an error message that could be more descriptive, and somewhat weird default paths.

from atom-racer.

I am receiving this error and I do have options properly configured. I have a custom path for racer which is set, yet this still shows.

from atom-racer.

Is racer actually configured properly (e.g. does path/to/racer complete std::io::B show completions or error) on your system? Also, does the racer path in the options point to the executable, not the directory it's in, and does the rust source path actually point to a directory with the rust sources in it?

from atom-racer.

1. Yes

$ racer complete std::io::B
MATCH BufReader,47,11,/home/chaos/repos/rustc-1.6.0/src/libstd/io/buffered.rs,Struct,pub struct BufReader<R> {

And Atom racer settings:

from atom-racer.

Oh okay, you only get that one error? Well, I just did the basic troubleshooting of things I went through by myself, seems like this might actually be a bug which the creator (@edubkendo) should have a look at.

from atom-racer.

I can confirm that the issue is now resolved.

from atom-racer.

For me works too.
Atom: 1.7.4
Rust: 1.8.0

from atom-racer.

I managed to fix this issue today via #61 (comment)

from atom-racer.

This is still happening on Windows 10. The autocomplete works but throws an error with every character typed. Quite unusable

from atom-racer.

I had this issue too, in my case I installed the racer package with atom package manager. Thing is, the package is installed as racer-v2, so when I set the path to the racer executable and rust sources, it kept throwing me this error because in file config.cson, those parameters where under "racer-v2" package section. I changed it to "racer" and it worked (config made within Atom's UI was erased).
