为 pypy 安装 numpy：没有名为 setuptools 的模块

Question

当我尝试使用命令提示符在 Windows 上设置 numpy 时

C:\numpy>pypy setup.py install

我明白了：

ImportError: No module named setuptools

但是 setuptools 好像已经安装了，是不是漏了什么？

>python -m pip install --upgrade pip setuptools 

Requirement already up-to-date: setuptools in 
c:\users\p\appdata\local\programs\python\python36\lib\site-packages

我还尝试使用 pypy3 而不是 pypy2 安装 numpy：

C:\numpy>pypy3 setup.py install 

但随后我收到以下错误（请耐心等待！:)）

C:\numpy>pypy3 setup.py install
Running from numpy source directory.

Answer 1

python -m pip install --upgrade pip setuptools 正在为 CPython 安装 setuptools。你需要说pypy -m pip install --upgrade pip setuptools。

您可能必须先说一次pypy -m ensurepip。
