解决 MacOS BigSur 使用 pip 安装依赖失败的问题

前言

年后到现在，我已经被基金伤透了心🤕

于是乎，为了争取不做 韭零后，我打算学习一下关于量化交易方面的内容。

学习量化交易，首先得先拿到交易的数据，这里我使用的是 聚宽数据 提供的本地数据接口，官方提供了 Python SDK，所以我就开始照着文档安装 SDK ……

照着文档的安装步骤，其实很简单：

$ pip install jqdatasdk

如果一切正常，那么你可以直接关掉本文了。

可如果你的环境和我一样：

• 系统版本：MacOS BigSur 11.2.3
• Python 版本：3.9
• IDE 版本：PyCharm Professional 2020.3

那么很有可能会安装失败，并且错误日志如下（截取部分日志）：

$ pip install jqdatasdk

  clang: error: invalid version number in 'MACOSX_DEPLOYMENT_TARGET=11'
  error: command '/usr/bin/clang' failed with exit code 1
  ----------------------------------------

此时，我们可以发现日志里的关键信息：

clang: error: invalid version number in 'MACOSX_DEPLOYMENT_TARGET=11'

解决办法

1. 检查当前系统 clang 版本

$ clang --version
Apple clang version 11.0.3 (clang-1103.0.32.62)
Target: x86_64-apple-darwin20.3.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

2. 再次检查系统CommandLineTools版本

$ softwareupdate --all --install --force
Software Update Tool

Finding available software
No updates are available.

这里其实是个坑，通过 softwareupdate 其实发现不了，我们通过另外一个工具检查下

$ brew doctor

working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: Your Command Line Tools (CLT) does not support macOS 11.
It is either outdated or was modified.
Please update your Command Line Tools (CLT) or delete it if no updates are available.
Update them from Software Update in System Preferences or run:
  softwareupdate --all --install --force

If that doesn't show you any updates, run:
  sudo rm -rf /Library/Developer/CommandLineTools
  sudo xcode-select --install

Alternatively, manually download them from:
  https://developer.apple.com/download/more/.

华生你发现了一个盲点！果然，homebrew 真是好用！🌝

Your Command Line Tools (CLT) does not support macOS 11.

3. 重新安装CommandLineTools

$ sudo rm -rf /Library/Developer/CommandLineTools
$ sudo xcode-select --install

根据网络环境，等待安装成功即可~

4. 再次检查 clang 版本

$ clang --version
Apple clang version 12.0.0 (clang-1200.0.32.29)
Target: x86_64-apple-darwin20.3.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

5. 重新安装 SDK 试试？

$ pip install jqdatasdk
......(省略部分日志)
Successfully installed SQLAlchemy-1.3.23 jqdatasdk-1.8.8 msgpack-1.0.2 pandas-1.2.3 pymysql-1.0.2 requests-2.25.1 thriftpy2-0.4.14

Enjoy~

后记

测试一下，踏出第一步：

from jqdatasdk import *

auth('xxxxxx', 'xxxxxx')

# 查询 贵州茅台[600519.XSHG] 近5天的交易数据
df = get_price('600519.XSHG', count=5, end_date='2021-03-10', frequency='daily')
print(df)

此时得到如下结果：

提示：当前环境 pandas 版本高于 0.25，get_price 与 get_fundamentals_continuously 接口 panel 参数将固定为 False
注意：0.25 以上版本 pandas 不支持 panel，如使用该数据结构和相关函数请注意修改

得到数据的同时，记得去专业的股票交易等网站去核对查询出来的数据是否准确哦~

因为这会直接影响到后面量化的指标！！
