Tkinter点击器游戏报pack_configure()缺self参数，点击计数功能失效

报错pack_configure() missing 1 required positional argument: 'self'的直接原因是你调用了Label类的pack方法，而非你实例化出的Label对象的pack方法，pack是实例专属方法，必须通过具体的Label对象调用，不能直接使用类名调用。

除此之外你的代码还存在两个可优化/修正的点：

• 每次点击都新建Label对象会导致界面不断堆叠计数标签，合理方案是提前创建1个计数Label，每次点击仅更新它的text属性即可
• 购买双倍点击的判断逻辑存在笔误，原代码中elif click >= 5需要修改为elif click >= 50，和前置判断逻辑对应

修正后的完整代码如下：

from tkinter import *
import time
from tkinter import messagebox

master = Tk()

def uiPrint():
    info()
    print("")
    print(click)
    blankLine()
Label_1 = Label(text = "Double click purchases need 50 clicks!")
Label_1.pack()

click = 0
mult = 1
dcp1 = 0

# 提前创建计数Label，避免每次点击新建
count_label = Label(master, text=str(click))
count_label.pack()

def blankLine():
    for i in range(20):
        print("")

def purchaseDoubleClicksCommand():
    global click
    global mult
    if click < 50:
        messagebox.showinfo("showinfo", "Not enough clicks!")
    # 修正判断条件的笔误
    elif click >= 50:
        mult = mult+1
        click = click - 50
        # 更新计数显示
        count_label.config(text=str(click))
        messagebox.showinfo("showinfo", "Double Clicks Purchased!")

def buttonCommand():
    global click
    global mult
    click += 1*(mult)
    # 直接更新已有Label的文本，无需新建
    count_label.config(text=str(click))

mainClickButton = Button(master, text="Click!", command = buttonCommand)
mainClickButton.pack()
    
purchaseDoubleClickButton = Button(master, text="Purchase Double Clicks", command = purchaseDoubleClicksCommand)
purchaseDoubleClickButton.pack()

master.title("Clicker!")
master.geometry("%sx%s+%s+%s" % (400,100,512,512))
mainloop()
