cargo install cargo-generate --features vendored-openssl failed

Question

I am trying to install terrain from terra-money. For that, the instructions said to follow the commands. I have run these instructions on ubuntu 20.04

1. Set 'stable' as the default release channel:

rustup default stable

# 2. Add WASM as the compilation target:

rustup target add wasm32-unknown-unknown

# 3. Install the following packages to generate the contract:

cargo install cargo-generate --features vendored-openssl
cargo install cargo-run-script

but when I run it, I am getting an error in the 3rd instruction. Can anyone please help

Answer 1

I just stumbled across the same error. I checked the OpenSSL requirements as per INSTALL file:

 OPENSSL INSTALLATION
 --------------------

 This document describes installation on all supported operating
 systems (the Unix/Linux family (which includes Mac OS/X), OpenVMS,
 and Windows).

 To install OpenSSL, you will need:

  * A make implementation
  * Perl 5 with core modules (please read NOTES.PERL)
  * The perl module Text::Template (please read NOTES.PERL)
  * an ANSI C compiler
  * a development environment in the form of development libraries and C
    header files
  * a supported operating system

I did not had perl installed, after installing it the build completed successfully. I hope you are only missing this perl installation.
