Question

我在Linux Mint上安装了sudo apt-get install node npm的Node，但它似乎根本不起作用。我创建了这个小脚本来检查是否发生了任何事情：

console.log('this is a test');
throw new Error();

当我从终端执行它时，绝对没有输出：没有日志，没有错误：

remi@remi-pc ~ $ node tests.js 
remi@remi-pc ~ $

任何人都知道如何解决这个问题？

Answer 1

尝试使用这些命令安装nodejs

curl -sL https://deb.nodesource.com/setup | sudo bash -

然后

sudo apt-get install -y nodejs

现在运行你的脚本

Below are the steps to install Node.js from source (OSX/linux)

NOTE - this installs Node.js which gives you both node as well as npm,
       they come together per release.

to start fresh remove prior node and npm installs as well as these :

    sudo mv ~/.npmrc ~/.npmrc_ignore
    sudo mv ~/.npm   ~/.npm_ignore
    sudo mv ~/tmp    ~/tmp_ignore
    sudo mv ~/.npm-init.js ~/.npm-init.js_ignore

download source from :    http://nodejs.org/download/

    cd node-v0.12.0

You may/should issue all following cmds as yourself NOT root (sudo)

Pick one of these NODE_PARENT locations to define where node gets installed into :

    export NODE_PARENT=/some/desired/install/path_goes_here
    export NODE_PARENT=/usr/local/bin/nodejs   # use this ONLY if you MUST install as root (sudo)
    export NODE_PARENT=${HOME}/node-v0.12.0 # Recommended - its owned by you NOT root

    export PATH=${NODE_PARENT}/bin:${PATH}      # jacks up PATH so executables are found later
    export NODE_PATH=${NODE_PARENT}/lib/node_modules # so node itself can find its modules dir

    ./configure   --prefix=${NODE_PARENT}

    make -j8  # if you have quad core use -j8 else -j4 ... it parallelizes make
    make install

which puts it into dir defined by above --prefix

when you use syntax :  npm install -g some_cool_module
the -g for global installs it into dir $NODE_PATH and not your $PWD

IMPORTANT - put above three  export xxx=yyy
commands into your ~/.bashrc or some such to persist these environment variable changes

On subsequent updates to Nodejs, just update your ~/.bashrc with new release name in
your NODE_PARENT env var , then source this ~/.bashrc and simply issue the configure/make/install as above

node - 运行脚本时没有任何操作
