$ babel和$ babel-node不会启动REPL

Question

I'm trying to setup babel on Ubuntu 14.04 but it doesn't seem to be working!

Here are some outputs that may be required:

$ which node
/usr/sbin/node
$ which nodejs
/usr/bin/nodejs
$ which babel
/usr/local/bin/babel
$ which babel-node
/usr/local/bin/babel-node

When I execute babel or babel-node the prompt just returns. The same happens on executing the commands with a filename as argument. (The file has just console.log("hello") .

How do I fix this?

Answer 1

The /usr/sbin/node vs /usr/bin/nodejs issue has been covered in Cannot install packages using node package manager in Ubuntu but basically Ubuntu has a separate node package that is NOT Node.js. The package for Node.js on Ubuntu is called nodejs . If you have both installed, it means your scripts will try to run using the other unrelated application. One option is to symlink nodejs to node .

The best solution however would be to use something like nvm to install node for your user without installing it globally. Then you can install and update node versions extremely easily, and your PATH will always reference node properly.

Answer 2

在/usr/local/bin/babel-node和/usr/local/bin/babel的第一行nodejs node更改为nodejs解决此问题。
