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

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

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.
