使用eval将字符串转字典时报错File "<string>", line 0

想把从txt里面读出来的字符串{"stuid": "1", "plus": "1.9", "num": "18.0", "work": "", "bonus": ""}转成字典
报错：
line = eval(line)
File "", line 0

SyntaxError: unexpected EOF while parsing

用了json.loads 和 ast.literal_eval都没有成功

这是相关代码片段

with open("temp_data_temp.txt", "r") as file_object:

     """写入每个人的分数"""
                num = 1
                while num < 59:    #写入分数
                    x = 3    #总纵轴
                    #当在写入左半边时
                    while x < 32:
                        line = file_object.readline()
                        line = eval(line)
                        y = 3    #总横轴
                        while y < 7:    #写入分数
                            if y == 3:
                                data = round(float(_check_save_data(line["plus"])), 1)
                            elif y == 4:
                                data = round(float(_check_save_data(line["num"])), 1)
                            elif y == 5:
                                data = round(float(_check_save_data(line["work"])), 1)
                            elif y == 6:
                                data = round(float(_check_save_data(line["bonus"])), 1)
                            sheet_weekly_report.cell(x, y).value = data
                            y += 1
                        x += 1
                    #当写入右半边时
                    while 31 < x < 61:
                        line = file_object.readline()
                        line = eval(line)
                        y = 9
                        while y < 13:
                            if y == 9:
                                data = round(float(_check_save_data(line["plus"])), 1)
                            elif y == 10:
                                data = round(float(_check_save_data(line["num"])), 1)
                            elif y == 11:
                                data = round(float(_check_save_data(line["work"])), 1)
                            elif y == 12:
                                data = round(float(_check_save_data(line["bonus"])), 1)
                            sheet_weekly_report.cell(x-29, y).value = data
                            y += 1
                        x += 1
                    num += 1

照理说eval和json.loads和ast.literal_eval这三种应该都是可以的，建议检查下别的地方，SyntaxError: unexpected EOF while parsing表示有语法问题
