python-项目骨架（powershell）

1.安装virtualenv

cd ~
pip list                     #查看pip安装列表
pip install virtualenv

2.创建文件夹，在里面安装虚拟环境

mkdir .venvs
virtualenvs --system-site-package .venvs/lpthw

3.激活虚拟环境

PS C:Usersxxxx> ..venvslpthwScriptsactivate
(lpthw) PS C:Usersxxxx>

在powershell执行脚本时报错，原因是powershell默认执行策略为Restricted，不支持运行脚本，可以对策略进行更改

PS C:Usersxxxx> ..venvslpthwScriptsactivate
..venvslpthwScriptsactivate : 无法加载文件 C:Userscrystaldu.venvslpthwScriptsactivate.ps1，因为在此系统上禁止
运行脚本。有关详细信息，请参阅 https:/go.microsoft.com/fwlink/?LinkID=135170 中的 about_Execution_Policies。

+ ..venvslpthwScriptsactivate
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : SecurityError: (:) []，PSSecurityException
    + FullyQualifiedErrorId : UnauthorizedAccess

①查询当前策略

PS C:Usersxxxxx> get-executionpolicy

②更改当前策略为remotesigned，关于更多执行策略可以参考：https://docs.microsoft.com/zh-cn/powershell/module/microsoft.powershell.core/about/about_execution_policies?view=powershell-6

PS C:Usersxxxx> set-executionpolicy remotesigned

 4.创建骨架项目目录

mkdir -p projects/skeleton/bin          #创建一个多级目录，-p 用/隔开
cd  projects/skeleton/bin
mkdir -p bin,NAME,tests,docs           #创建多个同级目录，-p 用,隔开

5.设置初始文件

(lpthw) PS C:Usersxxxprojectsskeleton> new-item -type file NAME/__init__.py
(lpthw) PS C:Usersxxxprojectsskeleton> new-item -type file tests/__init__.py

6.安装文件 setup.py  【C:Usersxxxxprojectsskeleton】

try:
    from setuptools import setup

except ImportError:
    from distutils.core import setup
    
    
config = {
    'description': 'My Project',
    'author': 'xxxx',
    'url': 'https://www.cnblogs.com/ohlala/',
    'download_url': 'xxxxx',
    'author_email': 'xxxx@163.com',
    'version': '0.1',
    'install_requires': ['nose'],
    'packages':['NAME'],
    'scripts':[],
    'name': 'projectname'
    }
    
setup(**config)

创建NAME_tests.py 【C:Usersxxxxprojectsskeleton ests】

from nose.tools import *
import NAME

def setup():
    print("SETUP!")
    
def teardown():
    print("TEAR DOWN!")
    
def test_basic():
    print("I RAN!", end='')

7.复制项目骨架

(lpthw) PS C:Usersxxxprojects> cp -r .skeleton ex47
(lpthw) PS C:Usersxxxprojectsex47> ls


    目录: C:Usersxxxprojectsex47


Mode                LastWriteTime         Length Name
----                -------------         ------ ----
d-----         2019/9/4     10:54                bin
d-----         2019/9/4     10:54                docs
d-----         2019/9/4     10:54                NAME
d-----         2019/9/4     10:54                tests
-a----         2019/9/4     10:17            469 setup.py


(lpthw) PS C:Usersxxxprojectsex47> mv NAME ex47
(lpthw) PS C:Usersxxxprojectsex47> ls


    目录: C:Usersxxxprojectsex47


Mode                LastWriteTime         Length Name
----                -------------         ------ ----
d-----         2019/9/4     10:54                bin
d-----         2019/9/4     10:54                docs
d-----         2019/9/4     10:54                ex47
d-----         2019/9/4     10:54                tests
-a----         2019/9/4     10:17            469 setup.py

(lpthw) PS C:Usersxxxprojectsex47> mv .	estsNAME_tests.py ex47_tests.py

然后修改ex47_tests.py中的代码

from nose.tools import *
import ex47

def setup():
    print("SETUP!")
    
def teardown():
    print("TEAR DOWN!")
    
def test_basic():
    print("I RAN!", end='')

 修改后执行nosetests进行测试

(lpthw) PS C:Userscrystalduprojectsex47> nosetests
.
----------------------------------------------------------------------
Ran 1 test in 0.037s

OK
(lpthw) PS C:Userscrystalduprojectsex47> nosetests -s
SETUP!
.I RAN!TEAR DOWN!

----------------------------------------------------------------------
Ran 1 test in 0.031s

OK
