“未知类型名称'decltype'”:在mac上安装pyicu失败,gcc错误

时间:2018-02-05 10:48:31

标签: python macos gcc pip pyicu

我运行了以下命令(因为我的mac上有python2和python3):

  

$ CFLAGS = -I / usr / local / opt / icu4c / include LDFLAGS = -L / usr / local / opt / icu4c / lib sudo python3 -m pip install pyicu

错误信息如下:

根据@ n.m。,import requests import json import csv response = requests.get(url).text //json source data = json.loads(response) newsdata = (data["response"]["docs"]) // These two lines reformat the date to what I want it to look like newsdate = [y["pub_date"] for y in newsdata] newsdate = [y.split('T')[0] for y in newsdate] newsdata["pub_date"] = newsdate // This line is what I've tried to replace the json newssnip = [y["snippet"] for y in newsdata] newshead = [y["headline"]["main"] for y in newsdata] for z in newsdata: csvwriter.writerow([z["pub_date"], //This is the JSON data i want to reformat z["headline"]["main"], z["snippet"], z["web_url"]]) 需要添加到CFLAGS。
