FileNotFoundError：[Errno 2]没有这样的文件或目录：'following.txt使用Selenium Python访问文件时出错
我有个问题。我正在尝试学习如何用Selenium编写机器人代码。一切正常，但我无法将从Instagram获得的关注者列表保存为txt文件。提前感谢您的帮助。

2件事
您将获得
DeprecationWarning: find_element_by_*命令在中已弃用
为了解决这个问题，您应该更改所有
find_element_by_* 命令到
find_element(By.XPATH, "XPATH")或发送到By.CSS_SELECTOR、By.ID等。这取决于你的选择器。
- 没有这样的文件
'following.txt：FileNotFoundError: Errno 2没有这样的文件或目录:Errno
您正在使用此行代码
with open("following.txt", "w", encoding="UTF-8") as file:你给了我
following.txt由于它不是full file path，Python将查看您运行程序的当前项目内部。
它可能不存在于当前工作目录中。
请确保它存在，如果不在当前工作目录中，则应提供完整的文件路径。
在windows系统上，它应该是这样的：
D:/FolderName/following.txt这只是一个例子。

首先，检查文件following.txt是否存在于工作目录中。
if followingCount != newCount:
followingCount = newCount
print(f"New count: {followingCount}")
time.sleep(3)
else:
break # <-- this line breaks the loop before writing the file.PS:尝试在另一个新的python脚本中读取和写入文件。如果它可以工作，这意味着在你的主代码中，文件的位置是不同的。

当您使用selenium4时，您的程序中有一个小问题和一个大问题，如下所示：
- DeprecationWarning: find_element_by_* commands are deprecated. Please use find_element() instead是一个DeprecationWarning。您可以在find_element_by_* commands are deprecated in selenium
中找到有关如何抑制它的详细讨论
此错误消息...
FileNotFoundError: [Errno 2] No such file or directory: 'following.txt'...implies您的程序无法在当前工作目录中找到文件following.txt：
c:\Users\murat\Desktop\Çalışmalarım\Programlama\Exercises\InstagramBOT解决方案
要解决此错误，可以采用以下两种方法中的任何一种：
确保在c:\Users\murat\Desktop\Çalışmalarım\Programlama\Exercises\InstagramBOT sub-directory.中放置了所需的文本文件
- 您还可以按如下方式传递所需文本文件
