我正在尝试安装新的 Regex 模块

readme.txt 说:::

To build and install regex for your default Python run 

    python setup.py install

To install regex for a specific version run setup.py with that interpreter, e.g.

    python3.1 setup.py install

我输入python setup.py install并返回/Library/Frameworks/Python.framework/Versions/7.3/Resources/Python.app/Contents/MacOS/Python: can't open file 'setup.py': [Errno 2] No such file or directory

我正在寻找答案，但人们一直在向我介绍 Python 文档，他们很困惑。

我知道这很简单，但我只是不确定为什么它不起作用。

这些说明中隐含的第一步是下载正则表达式的 tarball 或 zip 文件，解压缩，进入该目录，然后运行“python setup.py install”。请参阅http://docs.python.org/2/install/index.html#the-new-standard-distutils

如果您安装了 pip，则可以通过运行“pip install regex”来避免这些手动步骤。

很简单（在 Mac 上）：

  1. 安装easy_install curl https://bootstrap.pypa.io/ez_setup.py -o - | sudo python
  2. 安装点子 sudo easy_install pip
  3. 安装正则表达式模块 pip install regex

通过安装解决了这个问题python3-dev：sudo apt-get install python3-dev
