node.js - 在ubuntu 17.04上安装 Node

Question

我在 Ubuntu 上安装了 Node 8.0.0，然后按照 this answer to make it work 操作但现在当输入 node -v 时，它会显示 v4.7.2。我想要 v.8。我正在尝试安装的那个。是符号链接(symbolic link)有问题还是出了什么问题？

(Ubuntu 17:04)

我建议你删除ubuntu包

sudo apt-get remove --purge nodejs-*

然后执行下面的shell脚本来安装nodejs ...您必须使用下面提到的行的复制N粘贴来更新您的~/.bashrc ... vi install_node.sh

#!/bin/bash

# ............... top of cut  ........................  install_node.sh

export NODE_VER=v8.0.0  # see available versions at https://nodejs.org/dist/

# pick parent dir of nodejs install  ... comment out or remove ONE of below
# export CODE_PARENT_DIR=/opt/code  # root owned dir ... requires you to sudo prior to npm install going forward
export CODE_PARENT_DIR=${HOME}    # RECOMMENDED execute as yourself including npm install

# ......... following env vars are OK no edits needed

curr_OS=$( uname )

if [[ "${curr_OS}" == "Darwin" ]]; then

    OS_ARCH=darwin-x64

elif [[ "${curr_OS}" == "Linux" ]]; then

    OS_ARCH=linux-x64
else
    echo "ERROR - failed to recognize OS $curr_OS"
    exit 5
fi

if [[ -z ${CODE_PARENT_DIR} ]]; then

    echo "ERROR - failed to see env var CODE_PARENT_DIR"
    exit 5
fi

export NODE_CODEDIR=${CODE_PARENT_DIR}/nodejs
export COMSUFFIX=tar.gz
export NODE_NAME=node-${NODE_VER}
export NODE_PARENT=${NODE_CODEDIR}/${NODE_NAME}-${OS_ARCH} 

export PATH=${NODE_PARENT}/bin:${PATH}
export NODE_PATH=${NODE_PARENT}/lib/node_modules

# ............... end of cut  ........................  install_node.sh

# copy and paste above from ... top of cut ... to here into your file ~/.bashrc   

echo
echo "NODE_CODEDIR $NODE_CODEDIR<--"
echo

echo "mkdir -p ${NODE_CODEDIR}"
echo
      mkdir -p ${NODE_CODEDIR}
echo

echo "cd ${NODE_CODEDIR}"
      cd ${NODE_CODEDIR}
echo

# this is compiled code NOT source

[ -f ${NODE_NAME}-${OS_ARCH}.${COMSUFFIX} ] && rm ${NODE_NAME}-${OS_ARCH}.${COMSUFFIX} # if file exists remove

echo "wget -q --show-progress https://nodejs.org/download/release/${NODE_VER}/${NODE_NAME}-${OS_ARCH}.${COMSUFFIX}"
      wget -q --show-progress https://nodejs.org/download/release/${NODE_VER}/${NODE_NAME}-${OS_ARCH}.${COMSUFFIX}
echo

echo "tar -C ${NODE_CODEDIR} -xf ${NODE_NAME}-${OS_ARCH}.${COMSUFFIX}"
      tar -C ${NODE_CODEDIR} -xf ${NODE_NAME}-${OS_ARCH}.${COMSUFFIX}
echo

[ -f ${NODE_NAME}-${OS_ARCH}.${COMSUFFIX} ] && rm ${NODE_NAME}-${OS_ARCH}.${COMSUFFIX} # if file exists remove

# ...........  done ........... #

which node

node --version

# ....  bottom of file   install_node.sh
