+If you get this error, install `kfp` with the `--user` option:
+```bash
+pip3 install kfp --upgrade --user
+```
+This command installs the `dsl-compile` and `kfp` binaries under `~/.local/bin`, which is not part of the PATH in some Linux distributions, such as Ubuntu. You can add `~/.local/bin` to your PATH by appending the following to a new line at the end of your `.bashrc` file:
+
+```bash
+export $PATH=$PATH:~/.local/bin
 ```
 
 After successful installation, the command `dsl-compile` should be available.
