The “gopls: failed to install gopls(golang.org/x/tools/gopls@latest): Error: Command failed: /usr/local/go/bin/go install -v golang.org/x/tools/gopls@latest” error typically occurs when there’s an issue with the Go installation or configuration on your system. This error can be caused by a variety of factors, including:
- Corrupted Go installation
- Outdated Go version
- Permission issues with the Go installation directory
- Network connectivity problems
Troubleshooting Steps
Now that we’ve identified the potential causes, let’s dive into the step-by-step troubleshooting process:
Step 1: Verify Go Installation
First, ensure that Go is installed correctly on your system. Open a terminal and run the following command:
go versionIf Go is not installed or the version is outdated, download and install the latest version from the official Go website.
Step 2: Check Go Installation Directory Permissions
Verify that the Go installation directory has the correct permissions. Run the following command:
ls -ld /usr/local/goIf the output indicates that the directory is not owned by the current user or has restrictive permissions, adjust the permissions accordingly.
Step 3: Update Go Modules
Make sure that Go modules are up-to-date by running the following command:
go get -u golang.org/x/tools/goplsStep 4: Clear Go Cache
Sometimes, a corrupted cache can cause issues. Clear the Go cache by running:
go clean -cacheStep 5: Install Gopls Using Go Get
Try installing gopls using the following command:
go get -v golang.org/x/tools/gopls@latestIf the installation fails again, proceed to the next step.
Step 6: Check Network Connectivity
Ensure that your system has a stable internet connection. A network issue can prevent the installation of gopls.
Step 7: Use Gopls Installer Script
If all else fails, try using the gopls installer script:
wget https://raw.githubusercontent.com/golang/tools/master/gopls/install.sh
bash install.shThis script will download and install gopls, bypassing any potential issues with the Go installation.
