Error Messages and Solutions for Building Anchor Packages on Solana
As a developer working with the Solana platform, you are probably familiar with building and deploying packages using the Anchor framework. However, sometimes errors can occur when trying to build or deploy a package that relies on an outdated version of Rust. In this article, we will look at two common issues related to building Anchor packages: “Solana: Package solana-program vX.X.X cannot be built because it requires rustc X.X.X or later” and “error: package solana-program v1 18.26 cannot be built because it requires Rustc 1.75.0 or later 1.72.0-dev”
Issue 1: Solana: Package solana-program vX.X.X cannot be built because it requires rustc X.X.X or later
When you run anchor build, the command fails to compile your Solana package due to a mismatch between the required Rust version and the current Rust version used by Anchor. This error message indicates that the solana-program package relies on Rust 1.75.0 or later, but there is currently an active Rust version of 1.72.0-dev.
To resolve this issue, you need to upgrade your Rust version or use a compatible version of the solana-program package. Here are some steps to fix this error:
- Upgrade your Rust version: You can update to the latest stable or beta versions using the following commands:
bash
rustup upgrade --selfinstall
Alternatively, you can use `Rustup Tool Install --Upgrade
- Use a compatible version of thesolana-program
package: You can try downgrading to an earlier version or using a stable branch from the official Solana repository. For example:
bash
git clone
cd program solana
git checkout v1.19.0
- Rebuild your package: After updating your Rust version and switching to a compatible version of solana-program
, rebuild your package using the following command:
bash
anchor build
Issue 2: error: package solana-program v1.18.26 cannot be built because it requires rustc 1.75.0 or later, while the currently active rustc version is 1.72.0-dev
This error message indicates that the package solana-programrelies on a specific version of Rust, but there is currently an active version of Rust 1.72.0-dev.
To resolve this issue, you can:
- Downgrade Rust: You can update to the latest stable or beta versions using the following commands:
bash
rustup upgrade --selfinstall
Alternatively, you can use Rustup Tool Install --Upgrade
- Use a compatible version of thesolana-program
package: You can try downgrading to an earlier version or using a stable branch from the official Solana repository. For example:
bash
git clone
cd program solana
git checkout v1.17.0
- Rebuild your package: After updating your Rust version and switching to a compatible version of solana-program`, rebuild your package using the following command:
bash
anchor build
