SUMMARY

I'm stuck trying to install polkadot. I followed this instruction. It says that I should run:

cargo install --git https://github.com/paritytech/polkadot --tag <version> polkadot --locked

So I tried the following approaches:

ATTEMPT #1:

cargo install --git https://github.com/paritytech/polkadot --tag <version> polkadot --locked

Output:

bash: version: No such file or directory

ATTEMPT #2:

cargo install --git https://github.com/paritytech/polkadot --tag <0.9.31> polkadot --locked

Output:

bash: 0.9.31: No such file or directory

ATTEMPT #3:

cargo install --git https://github.com/paritytech/polkadot --tag 0.9.31 polkadot --locked

Output:

error: failed to find tag `0.9.31`

Caused by:
  reference 'refs/remotes/origin/tags/0.9.31' not found; class=Reference (4); code=NotFound (-3)

What am I doing wrong?

[ordian]

the tag starts with v, e.g. v0.9.31

Thanks, now I got past the obstacle :)
