Because something has gone wrong? 🙃

If you post the actual error someone might be able to suggest what to do. Without the error, it would only be guesswork. But also please include the versions of Node-RED, node.js (listed on start-up message of Node-RED) and which platform you are running on

You have an ancient version of npm, you are on 1.4.21, the latest is 6.x. Since it seems you are on a pi then, assuming you are running Raspbian, I suggest updating everything using the recommended pi install/upgrade script in the docs

After you have upgraded.... then the main error is that there is library missing so it won't compile...

```
../libusb/libusb/os/linux_udev.c:40:21: fatal error: libudev.h: No such file or directory
#include <libudev.h>
^

```

so you need to do

sudo apt-get update && sudo apt-get install libudev-dev

then retry the install
