安装 hashLib 会出现 SyntaxError: Missing parentheses in call to 'print'

问题描述

我需要一个简单的密码哈希函数，并认为我可以使用 hashlib.PyCharm 建议通过运行 pip install hashLib 来安装它.

I needed a simple hash function for passwords and thought I could use hashlib. PyCharm suggested to install it by running pip install hashLib.

但是现在 PyCharm 正在抱怨库中的语法错误:

But now PyCharm is complaining about a syntax error in the library:

Collecting hashLib
Using cached https://files.pythonhosted.org/packages/74/bb/9003d081345e9f0451884146e9ea2cff6e4cc4deac9ffd4a9ee98b318a49/hashlib-20081119.zip
Complete output from command python setup.py egg_info:
Traceback (most recent call last):
  File "<string>", line 1, in <module>

    print "unknown OS, please update setup.py"
          ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print("unknown OS, please update setup.py")?

----------------------------------------

Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/6_/8g1vyy5n1t1859x2d30ssk480000gn/T/pycharm-packaging/hashLib/

这表明这可能与我正在使用的 Python 版本有关(我尝试使用 Python 2.7 和 Python 3.8，但它们都不起作用).

It suggests that it may be a problem related to the Python version I am using (I tried with Python 2.7 and Python 3.8, but none of them worked).

确保您使用的是此软件包支持的 Python 版本.目前您使用的是 Python 3.8.

推荐答案

hashlib 现在在标准库中.这意味着您不需要安装它，它已经在您的 Python 安装中.

hashlib is in the standard library now. That means you don't need to install it, it's there already with your Python installation.

您尝试从 PyPI 安装的版本适用于 非常 旧版本的 Python (<= 2.4).

The one you tried to install from PyPI is for very old versions of Python (<= 2.4).
