Hi Filip! I am having some problems with Ganache. I successfully migrated the Helloworld contract to Ganache, but whenever I click on the “Contracts” tab and then click on “Helloworld”, Ganache crashes and I get just a blank screen. That happened yesterday, and I googled the problem online and somebody wrote that you just go back to Powershell and type in “trufffle migrate --reset”.
That solved the problem yesterday, but today I am encountering the same problem (blank screen) and entering “truffle migrate --reset” isn’t fixing the problem. Please help!
Hi @ImRONMAN
Once you followed the steps suggested in my previous post (to create a local node_module folder and install truffle), you have to run the commands by always adding ./node_modules/.bin/ before the command.
For example ./node_modules/.bin/truffle migrate --reset
Give it a try.

No, I haven’t. I will try that later today. Thanks!
I reinstalled Ganache and it seems to be working now. Thanks!

Hey @chim4us, you terminal says that it is missing writing access, try to sudo.
sudo npm install -g truffle.
how you change the folder? to ethereum course advanced
thank you
Hi @chim4us
You are inside the folder node_modules but that does not look correct.
Try the following:
- Open your terminal;
- Write
cd - Write
sudo npm install -g [email protected]
Let me know how it goes.
Hi @christian20
Can you please elaborate your question?
In which folder are you?
The basic command to change a folder is cd
Keep me posted

You can drag and drop the project folder or open it as explained here: https://flight-manual.atom.io/getting-started/sections/atom-basics/#opening-modifying-and-saving-files
