Error with the initialization of Solana’s anchor on multiple projects
I am Mfoniso Orori, a developer who has encountered a common problem when I tried to initialize the Solana anchoring project on several projects. In this article, I will walk through the steps to solve the error and provide indications on how to avoid it in the future.
The problem: different load versions
When performing anchor initials on several projects, you often meet an error that seems to be:
`
Error: Impossible to analyze the lock file at: /home/mfoniso/desktop/code/sol/mycalculatuardApp/cargo.lock
Caused by:
The block file was found version 4, but this version of the load does not understand this lock file, ...
This error indicates that the Solana anchoring project is using a different version of thecargo.
Step 1: Identify the different versions
To solve this problem, it is necessary to identify which versions of the files cargo.lock are used on your projects. You can do it by checking the following:
- Open the
Cargo.Toml 'file for each project and look for the" Version "section.
- Check if any of the "version" sections has a different value from 1.0.0.
Step 2: Update the
version
After identifying which versions are used, you can update them to combine the version required by thecargo. To do this:
- Open the
cargo.Toml 'file for each project and change the" version "section to combine the desired version.
- If a project uses a previous version ofCargo.lock
, it may be better to update it all at once.
Step 3: Check the update
After updating the version, check that the problem has been solved by performing anchor initially on each project. If you are still finding problems, try updating cargo.toml files for both projects.
Additional tips and considerations
- Make sure the projects use the samecargo.
- Use the following command to update all Cargo.lock files in a directory:
`Bash
Update of the load -all
`
This will update all Cargo.lock files in the specified directory, including those on other projects.
Conclusion
When performing anchoring anchoring on multiple Solana anchor projects, it is common to meet errors relating to the different version of thecargo.lockfile. By following these steps, you can solve the problem and make sure all the projects use the same versions of the Cargo.lock file. In addition, using tools such asCargo Update -Allis can help simplify the process and prevent future problems.
Example of use case:
Suppose that you have two anchoring projects Solana,Project-a is Project-B. Both projects use version 1.0.0 of thecargo.toml. Manage anchor initials on both projects:
Bash
Project-a of Anchor Init
Anchor Init Project-B
`
On both projects, a cargo.lock file is created with different versions compared to 4. This can happen if you have made changes to thecargo.toml” files or if you use different load versions.
After identifying the problem, the version of the files is updated.
`Toml
[Project-a]
version = “1.0.0”
`
And perform anchor init again:
Bash
Project-a of Anchor Init
Anchor init project-b
``
If everything is fine, the problem is solved and you can use your Solana anchoring projects without further problems.
