Hello @CoderWithAttitude,
It would be great if you could provide more details such as the version you used, the command you typed, etc... If you have a screenshot, that can help too.

You opened #160 and #161 about an installation issue. Did you solve the installation problems before trying to run testrpc?

[elenadimitrova]

Experiencing the same issue on OSX after upgrading to OSX Sierra.

Tested with both v2.2.7 and v3.0.0 by running testrpc

app Elena$ testrpc

This was solved for me after reinstalling ethereum

brew tap ethereum/ethereum
brew uninstall ethereum
brew install ethereum

[porobov]

Same here. Reinstalling ethereum doesn't work.
nodejs v6.9.1
ubuntu 14.04

[next-jesusdiazvico]

I'm having the exact same problem as @porobov.

[fanatid]

@porobov @beeva-jesusdiaz remove and install testrpc from scratch
the problem is that scrypt package was compiled with other node version
secp256k1 will work in any case (even if you see message "Secp256k1 bindings are not compiled. Pure JS implementation will be used.")

[chevdor]

1. uninstall testrcp: npm uninstall -g ethreumjs-testrpc
2. make sure you have node version 6.x or above (if not, fix that first)
3. ensure you delete the old testrpc: sudo rm -rf /usr/local/lib/node_modules/ethereumjs-testrpc
4. reinstall: npm i -g ethereumjs-testrpc

[comodoro]

I got this message with newer node (7.4.0) and with testrpc already running elsehere (which may be irrelevant). Only after reinstalling node to 6.9.5 the correct message about testrpc already running was shown.
