I'm trying to install truffle on VS Code(in window 10) after installing node.js, npm and ganache. All the above three have been installed and worked but When I tried to install truffle in VS Code in terminal, these kinds of errors occurring again and again. What should I do? This is the first pic when I tried to install it

You can check the version of node and npm first. I had this error before, solving by changing npm version to v6 and node version to v16.

  • Emily Li, I have installed the latest version of node and npm. But this is still occurring.

  • I mean lastest version may bring to these errors. You may try to downgrade it.

  • Currently, my npm version is 8.5.5 and node is v16.15.0. Which version should I install.

  • run npm install -g npm@6 in terminal will change the version of npm to v6
