python & pycharm

1、 Windows下載安裝python

　　1. 進入官網http://python.org/下載python（2.x 0r  3.x）

　　2. 安裝：選擇一個盤安裝，直接下一步至完成

　　3. 配置環境變量：

　　D:Python27;

　　D:\Python27\Scripts;

　　D:\Python27\Tools\driver;

　　4. 驗證是否生效：cmd下輸入python

　　

　　5. 下載的python通常都有pip，用pip下載相關庫便可

　　

 

2、安裝pycharm

　　1. D:\Program Files\JetBrains\PyCharm Community Edition 2018.3.5

　　2. pycharm中增長svn

• VCS—Browse VCS Repository—Browse Subversion Repository
• 添加SVN 1.8（若是沒有1.8的話，那應該是svn版本不夠，須要升級或修復svn）
• 添加svn地址
• 選擇一個檢出的文件夾，checkout代碼
• 修改代碼，嘗試提交代碼 

 

3、linux下安裝python

1. rpm -qa yum  查詢是否安裝yum

 

 

 

 

Linux下安裝python 2.7

 

安裝依賴的庫

yum -y install python-devel openssl openssl-devel gcc sqlite sqlite-devel mysql-devel libxml2-devel libxslt-devel

Python

**================================================= **

下載python 2.7.13

www.python.org

[root@server2 ~]# mkdir /software [root@server2 ~]# cd /software/ [root@server2 software]# wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz [root@server2 software]# ll 總用量 36852 -rw-r--r-- 1 root root 17076672 12月 18 04:21 Python-2.7.13.tgz -rw-r--r-- 1 root root 20656090 1月 17 16:07 Python-3.5.3.tgz 

解壓文件

[root@server2 software]# tar -zxf Python-2.7.13.tgz

進入目錄

[root@server2 software]# cd Python-2.7.13

編譯安裝

[root@server2 Python-2.7.13]# ./configure --prefix=/usr/local/python2.7 --with-threads --enable-shared [root@server2 Python-2.7.13]# make && make altinstall 

備份舊python相關命令

===> 有些版本/usr/bin/目錄下不存在pip 忽略下面第一行命令便可 [root@server2 Python-2.7.13]# mv /usr/bin/pip /usr/bin/pip_old [root@server2 Python-2.7.13]# mv /usr/bin/easy_install /usr/bin/easy_install_old [root@server2 Python-2.7.13]# mv /usr/bin/python /usr/bin/python_old 

新版本python命令作軟鏈接，快捷使用

[root@server2 Python-2.7.13]# ln -s /usr/local/python2.7/lib/libpython2.7.so /usr/lib [root@server2 Python-2.7.13]# ln -s /usr/local/python2.7/lib/libpython2.7.so.1.0 /usr/lib [root@server2 Python-2.7.13]# ln -s /usr/local/python2.7/bin/python2.7 /usr/bin/python [root@server2 Python-2.7.13]# ln -s /usr/local/python2.7/lib/libpython2.7.so /usr/lib64 [root@server2 Python-2.7.13]# ln -s /usr/local/python2.7/lib/libpython2.7.so.1.0 /usr/lib64 

測試python是否能夠正常使用

[root@server2 ~]# python Python 2.7.13 (default, Apr 11 2017, 11:14:36) [GCC 4.4.7 20120313 (Red Hat 4.4.7-18)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> 

安裝pip

下載最新版的pip，而後安裝

[root@server2 Python-2.7.13]# cd /software/ [root@server2 software]# wget https://bootstrap.pypa.io/get-pip.py [root@server2 software]# python get-pip.py 

查找pip的位置

[root@server2 software]# find / -name pip
/usr/local/python2.7/bin/pip

找到pip2.7的路徑，爲其建立軟鏈做爲系統默認的啓動版本

[root@server2 software]# ln -s /usr/local/python2.7/bin/pip /usr/bin/pip 

測試pip是否可用

[root@server2 software]# pip install Pillow Collecting Pillow Downloading Pillow-4.1.0-cp27-cp27m-manylinux1_x86_64.whl (5.7MB) 100% |████████████████████████████████| 5.7MB 129kB/s Collecting olefile (from Pillow) Downloading olefile-0.44.zip (74kB) 100% |████████████████████████████████| 81kB 541kB/s Building wheels for collected packages: olefile Running setup.py bdist_wheel for olefile ... done Stored in directory: /root/.cache/pip/wheels/20/58/49/cc7bd00345397059149a10b0259ef38b867935ea2ecff99a9b Successfully built olefile Installing collected packages: olefile, Pillow Successfully installed Pillow-4.1.0 olefile-0.44 

安裝easy_install

下載最新版的easy_install，而後安裝

[root@server2 software]# wget https://bootstrap.pypa.io/ez_setup.py [root@server2 software]# python ez_setup.py 

找到easy_install的路徑，爲其建立軟鏈做爲系統默認的啓動版本

[root@server2 software]# ln -s /usr/local/python2.7/bin/easy_install /usr/bin/easy_install 

測試easy_install是否可用

[root@server2 software]# easy_install beautifulsoup4 Searching for beautifulsoup4 Reading https://pypi.python.org/simple/beautifulsoup4/ Downloading https://pypi.python.org/packages/9b/a5/c6fa2d08e6c671103f9508816588e0fb9cec40444e8e72993f3d4c325936/beautifulsoup4-4.5.3.tar.gz#md5=937e0df0d699a1237646f38fd567f0c6 Best match: beautifulsoup4 4.5.3 Processing beautifulsoup4-4.5.3.tar.gz Writing /tmp/easy_install-OSpCW5/beautifulsoup4-4.5.3/setup.cfg Running beautifulsoup4-4.5.3/setup.py -q bdist_egg --dist-dir /tmp/easy_install-OSpCW5/beautifulsoup4-4.5.3/egg-dist-tmp-m3PXo5 zip_safe flag not set; analyzing archive contents...

yum 安裝工具只支持系統自帶的python版本， 修改配置文件使其可正常使用

查看原版本python

[root@server2 software]# ll /usr/bin/python* lrwxrwxrwx 1 root root 34 4月 11 11:20 /usr/bin/python -> /usr/local/python2.7/bin/python2.7 lrwxrwxrwx 1 root root 6 2月 15 14:33 /usr/bin/python2 -> python -rwxr-xr-x 2 root root 9032 8月 18 2016 /usr/bin/python2.6 ==> 這個就是系統自帶的python -rwxr-xr-x 1 root root 1418 8月 18 2016 /usr/bin/python2.6-config lrwxrwxrwx 1 root root 16 4月 11 10:47 /usr/bin/python-config -> python2.6-config -rwxr-xr-x 2 root root 9032 8月 18 2016 /usr/bin/python_old 

修改配置文件 /usr/bin/yum

#!/usr/bin/python ===> 修改成 #!/usr/bin/python2.6 

測試yum是否可用

[root@server2 software]# yum -y install python-devel
已加載插件：fastestmirror, security 設置安裝進程 Loading mirror speeds from cached hostfile * epel: mirrors.aliyun.com 包 python-devel-2.6.6-66.el6_8.x86_64 已安裝而且是最新版本 無須任何處理 

好了，大功告成。

優化

編寫一鍵安裝python2.7的腳本

因爲Centos 6.x的系統默認都是python2.6 ，若是服務器須要用2.7環境的話每臺都得手動操做升級，工做量比較大， 編寫腳本提高效率。（Centos 7.x版本的默認的python都是2.7.5版本）

建立用於存放python腳本的目錄

[root@server2 software]# mkdir /script/python/ [root@server2 software]# cd /script/python/ 

因爲國外python網站下載python安裝包緩慢，能夠提早下載下來，和install_py27.sh放在一塊兒，在腳本中直接解壓本地文件進行安裝，我已經上傳到網盤
點擊我下載

開始編寫腳本 install_py27.sh

把Python-2.7.13.tgz文件和install_py27.sh腳本下載下來，放在同一個目錄下：
運行下面命令進行安裝

/bin/sh install_py27.sh

安裝完成後執行python查看版本
