Does anyone have an updated environment spec?

I have followed the presentation up to the ‘npm install’ command. Then all hell breaks loose!

TestRPC is now replaced by ganache-cli,and so from the completion of npm install I am not even sure whether I am seeing what is expected.

Is there an updated package.json file that I can use? The difference between the one in the lecture and reality is just a bit too wide for me.

Thanks!

    Hi David,

    You can replace testrpc with either ganache-cli or by using the graphical UI ganache program. Either one or both would work. Here is a list of the latest packages and their versions. Hope this helps.

    ganache-cli: 6.1.0
    web3: 1.0.0-beta.33
    solc: 0.4.21

    Ok I managed to fix the node-gyp issues with the python version by using:

    npm config set python python2.7.

    Thanks Riya
