Currently updated to slice machine 1.0.2 and I am having trouble running it when I run pnpm start-slicemachine. Error : 'start-slicemachine' is not recognized as an internal or external command, operable program or batch file. I appreciate your help. Thanks ---

have you tried running `npm run slicemachine`? ---

Turns out this is a pnpm issue. Changing to npm, and all works well. Can't figure out why it is happening. ---

I have the same problem, after installing and configuring the slicemachine "pnpx @slicemachine/init@latest", when running the script "pnpm run slicemachine", the error occurs: ELIFECYCLE Command failed with exit code 1. ---

Shift your the project to use `npm` for now. Hopefully the prismic team will fix this soon. An issue was opened on this topic - [Link](https://github.com/prismicio/slice-machine/issues/768) ---

👏 👏 Now fixed for `pnpm` and `yarn` in the latest release of `slicemachine 1.4.0`
