Hello @captainmaps what's your OS, which versions of Rust and Cargo do you use and how did you install Rustlings? Did you get any errors?

I installed it 2 days ago as following:

1. git clone https://github.com/rust-lang/rustlings
2. cd rustlings
3. cargo install --force --path .

as described here: https://github.com/rust-lang/rustlings#manually

After it, I was able to run rustlings.

I use windows 10 and I use the stable build of rust. do you run command 3 like that or do you have to put a path at the end of it? I did use powershell to install it, but some error still happen.

PS C:\WINDOWS\system32\rustlings> cargo install --force --path C:\WINDOWS\system32\rustlings

do you run command 3 like that or do you have to put a path at the end of it?

The path is the dot . which points to the current directory - and previously I switched to that directory.

Your error is the path:

could not canonicalize path: 'C:\WINDOWS\system32\rustlings'

The backslash is often used for escaping chars. So either try it with a dobule backslash, a normal slash or with the dot .
cargo install --force --path .

I tried it with the dot but this warning still comes up:

PS C:\WINDOWS\system32\rustlings> cargo install --force --path .
warning: could not canonicalize path: 'C:\WINDOWS\system32\rustlings'

I stopped the command after that.

This issue is probably related to rust-lang/rustup#999 rust-lang/rustup#682

I just re-run the 3 installation steps and it worked as expected. Since your error stack also consists of multiple warning: spurious network error, it could also something related to a proxy or antivirus program.

btw I'm using PoweShell Core: https://github.com/powershell/powershell

could the execution policy have something to do with this? I think those are affecting scripts running and I have it restricted.

Nope. No difference.

I tried the other method for installing and this is what I found:

PS C:\WINDOWS\system32> Start-BitsTransfer -Source https://git.io/JTL5v -Destination $env:TMP/install_rustlings.ps1; Unblock-File $env:TMP/install_rustlings.ps1; Invoke-Expression $env:TMP/install_rustlings.ps1
Let's get you set up with Rustlings!

I don't know if this error is the same as the last method.

Can you check out this solution https://stackoverflow.com/questions/46232906/git-clone-error-rpc-failed-curl-56-openssl-ssl-read-ssl-error-syscall-errno

But they also state, that it's likely a problem with antivirus, firewall, outdated Software etc

#668 could also be the solution for you.

I did have a similar problem before though, it was about an app called itch. It had an error about installing butler. My solution for it was manually downloading butler and putting in the PATH's. Maybe I can do a similar solution to this one.

The problem here is that the rustlings command doesn't work. The exercises part is working fine, but compiling is where it would take so long. The amount of time it takes to compile coupled with frequently needing to check is not gonna be good. Hence why I need the rustlings command. It checks at intervals so I don't have to wait that long just to know if my solution is right or wrong.

I finally did it!!! all I had to do was not launch Powershell in administrator and use a different path for installation.
