pyinstaller打包报错 with open(path, 'rb') as stream: FileNotFoundError: [Errno 2] No such file or directory: 'd:\\python3.6.8\\lib\\site-packages\\prettytable-3.8.0-py3.6.egg\\EGG-INFO\\top_level.txt' 中文回答我 看起来你在使用 PyInstaller 打包你的 Python 程序时遇到了问题。出现这个...
同样,在处理二进制文件时,我们需要使用二进制模式打开文件。 importinspect# 获取文本文件的路径file_path=inspect.getfile(open('text_file.txt','r'))print(file_path)# 获取二进制文件的路径file_path=inspect.getfile(open('binary_file.bin','rb'))print(file_path) 1. 2. 3. 4. 5. 6. 7. 8. ...
使用pyinstaller 打包exe总是失败, with open(src_path, 'rb') as fp: FileNotFoundError: [Errno 2] No such file or directory: 'd:\\Python\\python-3.7.9\\python37.zip\\struct.pyc' ,解决不了这个问题,试了N多办法,心瑟瑟。解决方法: 原因:embed amd64.zip包不完整,缺少很多东西 解决方法:安装...
>>>f =open('E:\python\python\gbk.txt','r', encoding='gbk', errors='ignore') 二进制文件 前面讲的默认都是读取文本文件,并且是UTF-8编码的文本文件。要读取二进制文件,比如图片、视频等等,用'rb'模式打开文件即可: >>> f =open('E:\python\python\test.jpg','rb') >>> f.read() b'\xff...
如果是配置文件,调用readlines()最方便:with open("test.txt","r") as file: for line in file.readlines(): print(line.strip())# 把末尾的’\n’删掉 相关参数:r: 以只读方式打开文件。文件的指针将会放在文件的开头。这是**默认模式**。 rb: 以二进制格式打开一个文件用于只读。文件指针将会放在文件...
f=open('/Users/michael/gbk.txt','r',encoding='gbk',errors='ignore') 二进制文件 前面讲的默认都是读取文本文件,并且是UTF-8编码的文本文件。要读取二进制文件,比如图片、视频等等,用'rb'模式打开文件即可: f.read() b'\xff\xd8\xff\xe1\x00\x18Exif\x00\x00...' # 十六进制表示的字节 ...
I notice that I can open a file like this: f=open("a.dat","rb") And another method: with open("a.dat","rb") as f: In my opinion, if I use the first one, I must call f.close() function, while the second method need not. Am I right? Or there would be better m...
with open(’/path/to/file’, ‘r’) as f: print(f.read()) 这和前面的try … finally是一样的,但是代码更佳简洁,并且不必调用f.close()方法。 调用read()会一次性读取文件的全部内容,如果文件有10G,内存就爆了,所以,要保险起见,可以反复调用read(size)方法,每次最多读取size个字节的内容。另外,调用...
with open(self.filename, 'ab') as f: pickle.dump(data, f) def readiter(self): # 读取 with open(self.filename, 'rb') as f: while True: try: data = pickle.load(f) yield data except: break 二、python源码解释 def open(file, mode='r', buffering=None, encoding=None, errors=None...
I noticed that when using with open to read a json, using either r or rb parameters returns identical results. with open('something.json', 'rb') as f # 'r' returns the same thing t1 = json.load(f) However, when I write to a json with wb, I get an error...
