cannot init template

[daef]

I get a strange error trying to init the rust-webpack template:

Any hints where to start looking? rust and wasm-pack are fresh installations.

That's strange, the only commands that we spawn during installation are git and npm, I assume you both have this commands.

@fitzgen I can't see the appveyor builds, are we passing the installation on windows?

looks like https://github.com/rustwasm/rust-webpack-template/issues/95 might be related...

it gets better: it seems to work when I bang in the create-rust-webpack.js into a node instance manually:

i am still having this problem. Did anyone find a solution?

[minagawah]

I upgraded my Git version from 2.7.4 to 2.22.0, and it now works fine. Reason being, create-rust-webpack seems to use --no-tags option when git clone, and older version of Git does not have such option.

I hit the same issue, here's an informative traceback that shows git failing:

I ran the git command in isolation and can confirm that git version 2.11.0 does not support --no-tags.

Running Ubuntu 18.04, git version 2.25.1, getting the same error.

upgrading git to 2.27.0 fixed issue.

[madprogramer]

On macOS Catalina, upgrading git also fixed it for me.
