没有这样的文件或目录尝试使用pip安装fcntl时出错

Question

我正试图用pip安装fcntl，并将其输入cmd:

pip install pycopy-fcntl

然而，这个错误弹出，我不知道它是什么，也不知道如何修复：

Collecting pycopy-fcntl

有没有想过我该怎么解决这个问题？

https://github.com/pfalcon/pycopy-lib#readme说：

pycopy lib是一个为pycopy项目开发非单片标准库的项目

它不是一个可安装pip的库，甚至根本不是Python库。这是Pycopy的一个库(https://github.com/pfalcon/pycopy#readme)：

Pycopy旨在开发和维护一种极简主义、轻量级和可扩展的Python(兼容(语言实现。

您真正想安装什么？模块fcntl？这是一个来自stdlib的模块：https://docs.python.org/2.6/library/fcntl.html
