我试图做到这一点，以便制作人员名单文本文件中的每一行都在制作人员名单菜单中换行，但是制作人员名单菜单没有加载，并且出现了我无法理解的错误

您打开 Credits.txt 的方式并不正确。而不是下面的代码片段

# Opening the text file so that it can be put onto the screen
CreditFile = open("Credits.txt", "r")
CreditFileText = CreditFile.read()
LineCount = len(open("Credits.txt").readlines())
for i in range(1, LineCount):
    # Putting the text onto the screen so that it can be read
    Text = open("Credits.txt").readlines(i)
    CreditText = SmallMenufont.render(Text, True, (238, 238, 238))
    screen.blit(CreditText, (0, 0))

您可以简单地打开文件并逐行遍历它：

with open("Credits.txt", "r") as credits_file:
    for line in credits_file:
        # Do something with 'line' (your code is below)
        CreditText = SmallMenufont.render(line, True, (238, 238, 238))
        screen.blit(CreditText, (0, 0))
