while installing stellar-cli Error : can't find crate for hyper

[happylucktoday]

What I did

I was installing stellar-cli
I used command cargo install --locked stellar-cli
while it is compiling I faced an error:
error[E0463]: can't find crate for hyper
and so many errors related with 'hyper'
I don't understand what issue there is.

Thanks for letting us know.

Does the following work?

cargo install --locked cargo-binstall
cargo binstall -y stellar-cli

Also
What OS are you on?

rustc --explain E0463

A crate was declared but cannot be found.
extern crate foo; // error: can't find crate

You need to link your code to the relevant crate in order to be able to use it (through
Cargo or the -L option of rustc, for example).

Common causes

• The crate is not present at all. If using Cargo, add it to [dependencies]
  in Cargo.toml.
• The crate is present, but under a different name. If using Cargo, look for package
  = under [dependencies] in Cargo.toml.

Common causes for missing std or core

• You are cross-compiling for a target
  which doesn't have std prepackaged. Consider one of the following: + Adding
  a pre-compiled version of std with rustup target add + Building std from
  source with cargo build -Z build-std + Using #![no_std] at the crate root,
  so you won't need std in the first place.
• You are developing the compiler itself and haven't built libstd from source. You
  can usually build it with x.py build library/std. More information about
  x.py is available in the rustc-dev-guide.

I am using windows 10
When I try install, it works.
I tried a hello-world project on soroban test net
It works once, then doesn't work.
If I try several times, it is working well, then does not work
What is the issue?
Is is related with upload/download speed?
I tried on VPS, but I can not install rust
Please help me

So the install is working, but when using the CLI it fails?

If so what errors are you getting?

[janewang]

So on your Windows 10, you have rust and the project is working. Worst case, you can remove the current hello-world project and restart here https://developers.stellar.org/docs/build/smart-contracts/getting-started/hello-world.

For the VPS, not sure why you cannot install rust and not sure what the OS is, but you could check try this way: https://www.rust-lang.org/tools/install

Can we have a discussion about stellar on discord?

@happylucktoday There's an ongoing discussion about this issue on Discord here:

As the issue appears to be environmental (i.e. caused by the system setup) I'm going to close the issue as it doesn't sound like a problem with the CLI itself. If it turns out that was the wrong call we can reopen this issue or a new issue.
