Python 3.x标准模块库以及常用依赖安装

一、常用链接：

https://blog.csdn.net/sadfishsc/article/details/10390065

Unofficial Windows Binaries for Python Extension Packages:
https://www.lfd.uci.edu/~gohlke/pythonlibs/

二、库的安装

比如：pygame
（建议安装Anaconda，而不仅仅是安装Python环境）
如果安装了Anacaonda则自带PIP工具（如果没有安装PIP则通过链接去下载安装：https://pypi.python.org/pypi/pip#downloads，在cmd里cd到这个解压目录，输入python setup.py install即可完成PIP的安装）
1、下载whl文件（https://www.lfd.uci.edu/~gohlke/pythonlibs/中寻找）
pygame-1.9.4-cp37-cp37m-win_amd64.whl

2、在下载文件目录中执行：（中间会遇到各种问题）

C:\MySoftwares\Python-whl>pip install pygame-1.9.4-cp37-cp37m-win_amd64.whl

pygame-1.9.4-cp37-cp37m-win_amd64.whl is not a supported wheel on this platform.
You are using pip version 9.0.1, however version 19.0.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

（1）如遇上面的提示，则是由于版本不匹配造成的，需要升级PIP：

>python -m -pip install --upgrade pip

升级成功后，则再执行安装whl：

C:\MySoftwares\Python-whl>pip install pygame-1.9.4-cp37-cp37m-win_amd64.whl

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

（2）如遇上面的提示，则是由于需要的依赖openssl-devel没有安装：
两种安装方式：直接下载安装包安装；编译源码安装；

要想安装openssl-devel则需要安装perl（草莓版即可）和VS插件
Strawberry版本的perl，下载安装即可：https://www.perl.org/get.html
此种方法比较麻烦，如果是在Linux环境下可以一键搞定，但是在Windows环境下就很麻烦了。
可以参考：https://www.cnblogs.com/lpxblog/p/5382653.html

推荐采取直接安装的方式：http://slproweb.com/products/Win32OpenSSL.html下载对应版本。

安装完后：

C:\MySoftwares\Python-whl>pip install pygame-1.9.4-cp37-cp37m-win_amd64.whl

Requirement already satisfied: pygame==1.9.4 from file:///C:/MySoftwares/Python-whl/pygame-1.9.4-cp37-cp37m-win_amd64.whl in c:\mysoftwares\anaconda3\lib\site-packages (1.9.4)

三、Python程序的打包

1、如何将程序打成可执行的文件（.exe）
（1）安装Pyinstaller
首先要安装pywin32
下载安装文件：查找到跟自己适用的python版本及window系统版本匹配的pywin32，下载后安装：https://pypi.org/project/pywin32/#files
比如我下载的是：pywin32-224-cp37-cp37m-win_amd64.whl
使用pip命令安装：pip install pywin32-224-cp37-cp37m-win_amd64.whl

C:\MySoftwares\Python-whl>pip install pywin32-224-cp37-cp37m-win_amd64.whl
Processing c:\mysoftwares\python-whl\pywin32-224-cp37-cp37m-win_amd64.whl
Installing collected packages: pywin32
  Found existing installation: pywin32 223
    Uninstalling pywin32-223:
      Successfully uninstalled pywin32-223
Successfully installed pywin32-224

然后，再安装Pyinstaller（https://pypi.org/project/PyInstaller/#files），需要注意的是，一定要选择合适的版本，否则一定安装不成功

版本不匹配：
setup.py is not yet supposed to work. Please Use PyInstaller without installation.

我下载的是：PyInstaller 3.4，解压PyInstaller-3.4.tar.gz，在解压目录下执行：

>python setup.py install

C:\MySoftwares\Python-whl\dist\PyInstaller-3.4>python setup.py install

最后定位到要打包的py文件目录执行：

>pyinstaller -F myfile.py

即可。

2、更推荐的方式是利用IDE进行打包：（Pycharm）
在Pycharm的“Terminal”窗口中，执行：pip install pyinstaller，再执行：pyinstaller -F -w myFile.py

注意：
如果出现：

Original error was: DLL load failed: 找不到指定的模块。

则最好进行更新：

C:\Users\Xuekao.HU>conda upgrade numpy
Solving environment: done

  environment location: C:\MySoftwares\anaconda3
