evcxr_repl install fails about evcxr HOT 11 CLOSED

As an extra sanity check, you may want to check if you are actually using the version of rustc from rustup, via which rustc.

Thanks. It looks like a old version of cargo, which will mean an old version of rustc. In our previous email thread you said you'd upgraded, but perhaps at some point you've set the default to a specific version via rustup. Could you try having a play with rustup and see if you can get it so that cargo version reports 1.29.1?

See https://github.com/rust-lang-nursery/rustup.rs#override-precedence

Have a look at rustup show, and try:

• rustup override unset to remove the override in the current directory
• unsetting the RUSTUP_TOOLCHAIN env var
• remove a local rust-toolchain file in your project

from evcxr.

Other things you might try:
rustup override list
(to see what overrides are active)
rustup show
(show installed toolchains including which is default)

I'm not really familiar with how rustup switches versions. On Linux, at least for me, rustc and cargo are located in ~/.cargo/bin/. Perhaps uninstalling and reinstalling rustup is your best option at this point. Sorry I can't be of more help.
