Install Node. js in Linux

Install Node. js in Linux

Nodejs has been installed in Linux recently. This was a very simple thing, And I encountered some problems. To facilitate future reference, I recorded some important steps and problems for your reference. (After all, is it better to have a good memory :)).

Install Nodejs

I thought it was easy to install this because it was installed before and it was very smooth. But this time there was an accident:

First, download the installation package from the official node. js website. I downloaded this version: http://nodejs.org/dist/v0.10.26/node-v0.10.24.tar.gz.

// Download the installation package

Wget http://nodejs.org/dist/v0.10.26/node-v0.10.24.tar.gz

// Extract

Tar jxvf node-v0.10.24.tar.gz

./Configure

An error is returned...

./Configure

File "./configure", line 442

Fpu = 'vfpv3' if armv7 else 'vfpv2'

^

SyntaxError: invalid syntax

This is big. I only consulted G Jie. After some searches, I finally found a solution to the problem. See: http://stackoverflow.com/questions/14989164/node-js-configure-file-syntax-error-line-433. In fact, the python version is too low. In my system, it is 2.4.3. I read the post using python2.7 to solve this problem, so I upgraded python by using the gourd image.

1. Download python2.7.5

Wget http://legacy.python.org/ftp//python/2.7.5/Python-2.7.5.tar.bz2

2. decompress the file

Tar xvf Python-2.7.5.tar.bz2

3. Create an installation directory

Mkdir/usr/local/python27

4. Install python

Cd Python-2.7.5

./Configure -- prefix =/usr/local/python27

Make

Make install

5. Modify the old version of ln to point to (Note: After modification, yum usage may be affected)

Rm-f/usr/bin/python

Mv/usr/bin/python/usr/bin/python2.4.3

Ln-s/usr/local/python27/bin/python/usr/bin/python

Vi/usr/bin/yum (change the original/usr/bin/python to/usr/bin/python2.4)

Yum is written in python. Upgrading the new version of python will cause yum to become unavailable. The following is an error message when running yum:

There was a problem importing one of the Python modules

Required to run yum. The error leading to this problem was:

No module named yum

Solution:

Find the yum file and edit the py file.

[Root @ TC-Boss ~] # Which yum

/Usr/bin/yum

[Root @ TC-Boss ~] # Vi/usr/bin/yum

#! /Usr/bin/python changed to: Result of whereis python (earlier version of python)

#! /Usr/bin/python2.4

Then save OK.

Check the current python version:

Python -- version

Python 2.7.5

Now, the python upgrade and installation are complete, and the Nodejs installation continues.

Decompress the directory of nodejs, and then execute the./configure command. If no error occurs, make and make install. The installation is successful with a green light.

Test it and write hello. js with the content of console. log ('Hello nodejs ').

Node-v

V0.10.24

Node hello. js

Hello Nodejs

Now, nodejs has been installed successfully.
