How to solve truffle command not found error in blockchain

Question

I am trying to install truffle on my Ubuntu system. I have used the following code to install truffle:

$ sudo npm install -g truffle

Now I am trying to run the truffle list command on the terminal but I get the following error on execution:

-bash: truffle: command not found

How can I solve this?

Answer 1

First try restarting the system and then execute this command.

If it does not work then try make a new npm project and keep the dependencies local. To do it, you run the following commands:

$ run npm init
$ run npm i truffle
$ run ./node_modules/.bin/truffle init

If both the above solutions do not work, then it should be some problem with the version. So, install the latest
version of npm and node. You can do it by running the following command:

$ npm install -g truffle

Answer 2

Try installing truffle using the following commands:

$ npm install -g ethereumjs-testrpc
$ npm install -g truffle

Answer 3

Try installing truffle:

$ npm uninstall -g truffle
$ npm install -g truffle

Answer 4

Try installing it like this using npx:

$ npx truffle@5.0.2 unbox pet-shop

Answer 5

You can initiate truffle:

$ npm init truffle
