Python version control and the use of Django,git

First, install the pyenv

Install pyenv first install the RPM package environment required for Python compilation:

Yum Install ReadLine Readline-devel readline-static-y

Yum Install OpenSSL openssl-devel openssl-static-y

Yum Install Sqlite-devel-y

Yum Install Bzip2-devel bzip2-libs-y

Install Git

Yum Install git

Don't say much nonsense and start installing pyenv

git clone git://github.com/yyuu/pyenv.git ~/.pyenv

echo ' Export pyenv_root= ' $HOME/.pyenv ' >> ~/.BASHRC

echo ' Export path= ' $PYENV _root/bin: $PATH "' >> ~/.BASHRC

Echo ' eval ' $ (pyenv init-) "' >> ~/.BASHRC

EXEC $SHELL-L

Second, pyenv operation

Pyenv Install--list View installable versions

Install a Python version

Pyenv Install x.x.x

To view installed versions

Pyenv versions

* Indicates the version being used

Switch versions

Pyenv Global x.x.x

command to update the database

Pyenv Rehash

Uninstalling a version

Pyenv Uninstall x.x.x

Third, installation virtualenv

Pip Install Virtualenv

(Python can be used in the case of which version is used, and the version of the re-installed Python will need to be reinstalled virtualenv)

Create a new virtual environment

mkdir Project1

Virtualenv--distribute project1/

CD Project1

Activating and entering a virtual environment

SOURCE Bin/activate

Exiting a virtual environment

Deactivate

Iv. use of PIP

Install PIP

wget https://bootstrap.pypa.io/get-pip.py

Python get-pip.py

Note: python2.7.9 & python3.4 and its newer versions have their own PIP, no need to install separately

Update pip

Pip Install-u pip

Search Python Packages

PIP Search "Query"

Install package

Pip Install Six

To view installed packages

PIP List

V. Using GIT

Create a new warehouse

Git init

Shell commands dynamically view git status and branch

The first step is to clone the code first:

git clone git://git.kernel.org/pub/scm/git/git.git

Second Step copy Script

Copy the file Contrib/completion/git-completion.bash to the ~ and rename it to. git-completion.sh

Copy the file contrib/completion/git-prompt.sh to the ~ and rename it to. git-prompt.sh

You can take a look at the contents of these two scripts, with a brief introduction.

The third step is written. BASHRC the following content

SOURCE ~/.git-completion.sh

SOURCE ~/.git-prompt.sh

Export git_ps1_showdirtystate=1

Export git_ps1_showstashstate=1

Export Git_ps1_showuntrackedfiles=1

Export git_ps1_showupstream= "Verbose GIT svn"

Ps1= ' \[\033[1;31m\]\[email protected]\h \[\033[1;34m\]\w\[\033[1;31m\]$ (__git_ps1 "(%s)") \[\033[1;35m\], \[\ 033[0m\] '

The fourth step unregisters or restarts, at which point the command line should have changed. Success.

View git status

git status

Trace file

git Add File

Login

git config--global user.name "Wanezu"

git config--global user.email [email protected]

Submit File

Git commit-m "Commit"

Look again and you'll see that the catalog is clean.

git push

Git push-u Origin Master

Vi. Use of Githup

Create a Project login account

Create an empty Project

And then to the directory you specify (which can be a well-established program code)

CentOS will not push up.

Need to modify Vim. Git/config

Modify

[remote "origin"]

URL = https://github.com/youname/example.git

For:

[remote "origin"]

url = https://[email Protected]/youname/example.git

Vii. use of Django

Create a Django App

Django-admin Startapp Catelog

Viii. installation of Zsh

The shells are installed by default in 1.ubuntu

Cat/etc/shells

2. The version of the shell that is currently running

Echo $SHELL/bin/bash

3. Install zsh, git, and wget:

sudo apt-get install zsh git wget

4. Obtain and automatically follow Oh-my-zsh:

wget--no-check-certificate Https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh-O-| Sh

5. Replace bash for zsh:

Chsh-s/bin/zsh

6. Last reboot

Pip Install--allow-external Mysql-connector-python Mysql-connector-python
