如何阻止我的终端默认使用旧的Python 2.7.10来安装Pyperclip？

Question

我正在尝试将Pyperclip与Pip一起安装，但是我收到一条警告，说“ Python 2.7将于2020年1月1日到期。”并告诉我升级。之后，我在安装过程中遇到了很多错误。

我的系统上安装了Python 2.7.10和3.7.3。

启动pip install pyperclip时出现错误：

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

我希望Pyperclip能够正确安装。

const data = "Raúl, Moreno. Rodríguez Carlos";
const result = data.match(/\b[A-Z]/gm);
console.log(result);

您可能需要致电pip3而不是pip
