Python 2 Syntax Error Encountered in Python 3 Environment with ape Tool
问题
我在Python 3.9.17中使用eth-ape工具遇到了问题。
你好，我目前在Python 3.9.17中使用eth-ape工具遇到了问题。虽然我已经成功安装了它，但我遇到了与'print'语句相关的语法错误，这通常与Python 2的语法相关。以下是我收到的错误消息：
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.10/bin/ape", line 6, in <module>
from ape.main import main
File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/ape/__init__.py", line 109
print inspect.getdoc(self._tasks)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print(...)?
我对为什么会出现这个问题感到困惑，因为我正在使用Python 3来运行eth-ape。以下是我使用的Python版本：
python --version
Python 3.9.17
我已经确认eth-ape已安装在我的Python 3环境中：
python3 -m pip install eth-ape
Requirement already satisfied: ape in ./env/lib/python3.9/site-packages (0.4.0)
Requirement already satisfied: featuremonkey>=0.2.2 in ./env/lib/python3.9/site-packages (from ape) (0.3.1)
以下是我的deloy.py代码：
from brownie import accounts
def deploy_simple_storage():
account = accounts[0]
print(account)
def main():
deploy_simple_storage()
请问有人可以帮助我找到解决这个问题的方法吗？我将非常感激提供的任何建议或指导。在此先提前表示感谢！

I'm encountering an issue with the eth-ape tool in Python 3.9.17.
Hello, I am currently facing a problem with the eth-ape tool in Python 3.9.17. Although I have installed it successfully, I am encountering a syntax error related to the 'print' statement, which is commonly associated with Python 2 syntax. Here is the error message I received:
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.10/bin/ape", line 6, in <module>
from ape.main import main
File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/ape/__init__.py", line 109
print inspect.getdoc(self._tasks)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print(...)?
I am confused about why this issue is happening since I am using Python 3 to run eth-ape. Here is the version of Python I am using:
python --version
Python 3.9.17
And I have confirmed that eth-ape is installed in my Python 3 environment:
python3 -m pip install eth-ape
Requirement already satisfied: ape in ./env/lib/python3.9/site-packages (0.4.0)
Requirement already satisfied: featuremonkey>=0.2.2 in ./env/lib/python3.9/site-packages (from ape) (0.3.1)
below is my deloy.py code:
from brownie import accounts
def deploy_simple_storage():
account = accounts[0]
print(account)
def main():
deploy_simple_storage()
Can someone please help me find a solution to this problem? I would greatly appreciate any suggestions or guidance provided. Thank you in advance!

没有版本的 ape 支持过 Python 3。它也是一个已经停止维护的项目，最后一次发布是在2014年，仓库最后一次活动是在2017年，所以不会有任何版本支持Python 3。
> 我对为什么会出现这个问题感到困惑，因为我正在使用Python 3来运行ape。
是的，这就是为什么ape的Python 2的语法不起作用的原因。
从评论中我们可以看到，ape 实际上并不是你要找的项目。你想要的是完全不相关的包 eth-ape。卸载 ape 并安装那个包。
英文:
No release of ape has ever supported Python 3. It's also a dead project, with the last release in 2014 and the last activity on the repository in 2017, so no release is ever going to support Python 3.
> I am confused about why this issue is happening since I am using Python 3 to run ape.
Yes, which is why ape's Python 2-only syntax isn't working.
From the comments, we can see that ape isn't actually the project you're looking for. You want the completely unrelated package eth-ape. Uninstall ape and install that.

在Python 3中，print 需要使用括号。
>>> print("foo")
File "<stdin>", line 1
print("foo")
^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print("foo")?
>>> print("foo")
foo
而在Python 2中省略括号是完全有效的。
>>> print "foo"
foo
英文:
print in Python 3 requires parentheses.
>>> print "foo"
File "<stdin>", line 1
print "foo"
^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print("foo")?
>>> print("foo")
foo
Whereas it's perfectly valid in Python 2 to elide the parentheses.
>>> print "foo"
foo
