Issue

I am using poetry to manage a few of my Python projects. Recently I had to update the mysql-connector-python package to the latest version.

I found the following command to update the package to the latest version.

poetry update <package-name>

However, it didn’t work properly and it showed the following message.

$ poetry update mysql-connector-python

# Updating dependencies
# Resolving dependencies... (1.0s)

# No dependencies to install or update

Solution

After some research, I found the following command to update the package to the latest version. And the command is not actually update but add with the latest or specific version.

Update the package to the latest version

$ poetry add mysql-connector-python@latest

It worked and updated the package to the latest version.

Update the package to a specific version

$ poetry add mysql-connector-python==9.3.0

It worked and updated the package to the specific version.

Conclusion

We can use the following command to update the package to the latest or a specific version.

$ poetry add <package-name>@<version>
