Resolving Non-Zero Exit Status When Installing R Packages on macOS Catalina

If you're an R user working on macOS Catalina, you might have encountered the frustrating message: "installation of package had non-zero exit status." This issue commonly arises when attempting to install certain R packages. Let's delve into why you might be seeing this error and how to address it.

Understanding the Error

The "non-zero exit status" error typically indicates that the package installation was unsuccessful. This can be due to a variety of reasons, such as missing system dependencies, incompatible versions, or issues with compilation.

Common Culprit: Missing System Dependencies

One of the primary reasons for this error on macOS Catalina is the absence of necessary system dependencies. Many R packages, especially those that rely on C/C++ code for improved performance, need external libraries and tools to be present on your system.

Specific Package Issues

For instance, you might have faced this error when trying to install packages like broom. These packages might require compilation, which in turn requires tools like Xcode or specific libraries.

Steps to Resolve the Error

Install Xcode Command Line Tools:
Many R packages need Xcode's command line tools to compile. You can install them by running the following command in the Terminal:

Conclusion

Dealing with the "non-zero exit status" error can be frustrating, but by ensuring you have the necessary tools and dependencies installed, you can significantly reduce these issues. Following the steps outlined above should help you get back to productive work in R on your macOS Catalina system.

If you continue to face issues, consider reaching out to the package maintainers or looking for community support on forums and discussion groups.
