### 前言： ###

目前在做 支付宝的 “转账到支付宝账户” 功能，开放平台文档 提示需要下载 SDK工具。

[开放平台快速 快速开发地址：https://opendocs.alipay.com/open/309/106236][_https_opendocs.alipay.com_open_309_106236]

`其实 仔细细心一些，开发文档还是可以理解的`

言归正传

#### python 在安装支付宝sdk前 ,需要安装加密模块 pycrypto 2.6.1 ####

`即使你不执行这条命令，在你 pip install alipay-sdk-python 的时候也会执行下面这条命令，不信你看我 下面的 截图。`  
执行命令:

pip install pycrypto

如果是Windows系统，到这里可能安装出错了，可能出现的错误如下：

error: command ‘cl.exe’ failed: No such file or directory
    
    error: command ‘C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\cl.exe’ failed with exit status 2
    
    error: Microsoft Visual C++ 14.0 is required. Get it with “Microsoft Visual C++ Build Tools”: http://landinghub.visualstudio.com/visual-cpp-build-tools

所以目前来看的 **错误** 就是安装 `pip install pycrypto`

目前有两个解决方案：

#### 方案1 ####

--------------------

直接使用 pycryptodome

pip install pycryptodome

下载好后 下载阿里云的 SDK

[阿里云 SDK地址：https://pypi.org/project/alipay-sdk-python/3.3.398/\#files][SDK_https_pypi.org_project_alipay-sdk-python_3.3.398_files]

下载这个 压缩包

*  下载 解压后，将解压后的文件 `(alipay-sdk-python-3.3.398)` 放到 `python` 的 `Lib\site-packages` 的文件目录下，我的路径是 D:\\python\\Lib\\site-packages，
 *  进入到文件中修改 `setup.py, 将requires = ["pycrypto","rsa"] 修改成 requires = ["crypto","rsa"]`

进入此路径的 doc命令行

执行命令

python setup.py install

--------------------

#### 方案2 ####

--------------------

既然是 pycrypto的问题，那么就解决他。

在CMD命令行用 pip.exe install pycrypto 安装PyCrypto模块时 有这个报错：

`error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools`

这是因为pycrypto模块编译需要依赖Visual C++ 14.0的编译工具

*  安装Visual Studio 2015

[安装地址： http://download.microsoft.com/download/0/B/C/0BC321A4-013F-479C-84E6-4A2F90B11269/vs2015.com\_enu.iso][http_download.microsoft.com_download_0_B_C_0BC321A4-013F-479C-84E6-4A2F90B11269_vs2015.com_enu.iso]

然后就安装吧，当然安装位置你自己定

*  设置环境变量 **VCINSTALLDIR** 值为VC的安装路径，

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDY4NTg2OQ_size_16_color_FFFFFF_t_70 9]

*  重新打开CMD，键入set CL=/FI"%VCINSTALLDIR%\\INCLUDE\\stdint.h" 。再用pip安装就可以成功。

`pip有可能报 UnicodeDecodeError: 'utf-8' codec can't decode byte... 错误，这时需要将CMD的终端编码用“CHCP 65001”命令改为“UTF-8”后再安装。`
