Issue
While executing : cargo +nightly install --git https://github.com/alexcrichton/wasm-gc --force
in Ubuntu 18.04, is throwing
My system has following nightly version
rustc 1.47.0-nightly
cargo 1.47.0-nightly install --git https://github.com/alexcrichton/wasm-gc --force
Even, above command throws similar error!
Cmd1 : rustup toolchain install nightly
Cmd2 : rustup update
Even after running these commands as suggested over communities, error isn't resolved. I'm new to rust & couldn't link cargo to installed nightly via rustup.
System Details
cargo version : 1.43.0
rustup version : 1.22.1 (b01adbbc3 2020-07-08)
Cmd 3:
which cargo : /usr/bin/cargo
Solution
which cargo
printing out /usr/bin/cargo
indicates that it defaults to Cargo that you installed from your OS's package manager (apt).
Invocations with the toolchain version like cargo +nightly
are not a feature of Cargo, but rather Rustup. In fact, Rustup's cargo
is a link to rustup
that then invokes the "real" cargo stored under .rustup/toolchains
.
The easiest way to solve this would be to uninstall the Cargo you obtained from Ubuntu repositories:
$ apt remove cargo
Otherwise, you could try to manipulate your PATH
such that /home/<your_username>/.cargo/bin
comes before /usr/bin
.
If you do not have rustup installed yet, you need to install it.
$ brew install rustup-init # OSX
$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh # Ubuntu/Debian
Then configure rustup, you can set the config to default to start
$ rustup-init
Finally you can install specific version of rust, for instance nightly
$ rustup -v install nightly
