--- title: Common Problems --- Common Build Problems and Solutions =================================== The following are errors that you may encounter while building, installing, or running Rubinius along with suggested solutions. For any error, a first step is to ensure you have a current, clean checkout of Rubinius. Before going further, consider running the following steps: $ git co master $ git reset --hard $ git pull $ rake distclean $ rake Error: ERROR: unable to find runtime directory Rubinius was configured to find the runtime directory at: /Users/brian/devel/rubinius/runtime but that directory does not exist. Set the environment variable RBX_RUNTIME to the location of the directory with the compiled Rubinius kernel files. You may have configured Rubinius for a different install directory but you have not run 'rake install' yet. Solution: If you configured rubinius with a --prefix, run rake install. If you configured rubinius with a --prefix and renamed the install directory after installing Rubinius, re-configure Rubinius and reinstall it. If you renamed the source directory after building Rubinius, re-configure and rebuild it. In general, do not rename the source or build directory after building Rubinius.
