In the process of developing with golang, we often use the vendor directory. The vendor directory is a directory used to store dependent packages. These dependent packages exist in the same directory as the code we write ourselves, allowing us to easily manage the version information of dependent packages.
However, in some cases, we may need to close the vendor directory. In this article, we will discuss the necessity of closing the vendor directory as well as the specific steps and considerations.
The necessity of closing the vendor
For some special scenarios, it is necessary to close the vendor directory. The following points are listed below:
As the size of the project increases, the number of dependent packages in the vendor directory will also continue to increase. The version numbers, dependencies and other information of these dependent packages will bring unnecessary complexity to our code. After we close the vendor directory, we can place all dependent packages in the $GOPATH/src directory to reduce code complexity and improve code readability.
After closing the vendor directory, we can use the go get command to download the required dependency packages and explicitly specify the version of the dependency package. In this way, we can easily manage the version information of dependent packages and ensure that we are using the latest and most stable version.
Sometimes the two dependency packages we introduce in the vendor directory may have dependency conflicts, causing the program to not work properly Compile or run. By closing the vendor directory, we can use the go get command to download the latest dependency packages and manually handle dependencies to resolve dependency package conflicts.
Steps and precautions for closing vendor
Close the vendor directory is very simple, just delete the vendor directory. However, before closing the vendor directory, we need to do some preparations to ensure that the code compiles and runs smoothly.
If there are references to dependent packages in the vendor directory in the code, then after closing the vendor directory The program cannot be compiled and run normally. You need to ensure that all dependent packages in the code are referenced correctly.
After closing the vendor directory, we need to place all dependent packages in the $GOPATH/src directory. Make sure the $GOPATH directory is set correctly so we can use the go get command to download the required dependencies.
After closing the vendor directory, we can use the go get command to download the dependent package and clearly specify the version number of the dependent package . You can use the following command to download the dependent package:
go get -u package_name@version
Among them, package_name represents the name of the dependent package to be downloaded, and version represents the version number of the dependent package to be used. If you do not specify a version number, the latest version of the dependent package will be downloaded by default.
After downloading the dependent package, you need to ensure that the dependent package has been successfully downloaded and installed in the $GOPATH directory. You can use the following command to check:
go list -json -m package_name
Where, package_name represents the name of the dependent package to be checked. If the dependent package has been successfully downloaded and installed into the $GOPATH directory, information about the dependent package will be output.
If you are using an editor or IDE for development, after closing the vendor directory, you need to restart the editor or IDE in order to use It reloads dependent packages.
Summary
Close the vendor directory is a very simple task, but some preparations need to be done before closing to ensure the smooth running of the code. Closing the vendor directory can reduce code complexity, manage dependency package versions, and resolve dependency package conflicts. If you encounter problems with dependent packages when using golang for development, you can try closing the vendor directory to solve it.
