mac安装百度Python SDK的坑

摘要

本文记录了macOS Catalina安装baidu Python SDK的坑，主要是安装pycrypto坑太深了，折腾了好久。

系统

macOS Catalina版本10.15.2

出问题的关键点

查看了百度的文档，说需要先安装依赖——**pycrypto**，就是这个东西其坑无比。上来不管三七二十一，直接pip安装pycrypto，结果一大堆报错，然后直接去google pycrypto mac，安装了什么gmp之类的，结果牛头不对马嘴，问题还是没有解决，最后还是返回去看一大堆报错，报错中如下信息比较重要：

checking for gcc... gcc
    checking whether the C compiler works... no
    configure: error: in `/private/tmp/pip-install-rixi56fh/pycrypto':
    configure: error: C compiler cannot create executables

直觉上觉得是gcc有问题，于是通过brew安装gcc：

scarleastdeMacBook-Pro:hexo_auto scarleast$ brew install gcc
Updating Homebrew...
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
Error: The following formula
  gcc
cannot be installed as binary package and must be built from source.
Install the Command Line Tools:
  xcode-select --install

真的，看到又出错，真的冒火，索性log里面直接有提示，需要安装xcode，如下安装xcode即可：

scarleastdeMacBook-Pro:hexo_auto scarleast$ xcode-select --install
xcode-select: note: install requested for command line developer tools

输入xcode-select --install后，会弹出图形界面，按照提示安装就行了，安装完成查看gcc版本：

scarleastdeMacBook-Pro:hexo_auto scarleast$ gcc -v
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 11.0.0 (clang-1100.0.33.8)
Target: x86_64-apple-darwin19.2.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

其实发现并不是gcc，是clang，不过不影响接下来安装pycrypto了。

安装SDK过程

安装了xcode后就可以正常安装SDK了：

  • 安装pycrypto

哎，现在搞得人有点冒火，最后因为xcode的问题，没办法编译，导致的报错。还是那句话吧，出问题了先看日志，先看日志，先看日志！！！！
