npm install -g slap@latest fails

[macorifice]

Trying to install slap using npm install -g slap@latest but it gives me an error message:

npm WARN deprecated mkdirp@0.5.1: Legacy versions of mkdirp are no longer supported. Please update to mkdirp 1.x. (Note that the API surface has changed to use Promises in 1.x.)

Dupe of #414 and #411

[LeoMehraban]

happened to me, too

[slajerek]

This project seems to be abandoned. Is there any alternative? It fails for me too.

[JulesGM]

the author is dead #413

I had the same issues. The installation fails due to incompatibilities with current node versions.

I succeeded installing and running the editor version provided here by using node lts/argon v4.9.1, which was a current version when this repo was actively maintained.

In the meantime, there is a fork which runs under node lts/gallium -> v16.16.0: https://github.com/ajstrand/slap

If you really want to run and use the depricated version of this repo, you can use the Node Version Manager which allows you to maintain different node versions side by side.

• Once nvm is installed, install the appropriate node version for slap: nvm install --lts=argon
• Now you should be able to install the editor with: npm install --location=global slap@latest
• You can then run it with: slap
• Quit the editor by hitting CTRL-Q
• Switch back then to a current node version: nvm use stable
• Set an alias for running the depricated editor independent of the currently active node version as follows:
  alias slap="nvm run v4.9.1 $HOME/.nvm/versions/node/v4.9.1/lib/node_modules/slap/slap.js"
