"conda install" 没有安装到 pypy

Question

在 this post 之后，我为 pypy2.7 创建了一个环境：conda create -c conda-forge -n pypy2.7 pypy2.7。在新环境下我现在可以做

$ python -c "import sys; print(sys.executable)"
/usr/bin/python

和

$ pypy -c "import sys; print(sys.executable)"
/home/julian/miniconda2/envs/pypy2.7/bin/pypy

所以环境中没有python，因此使用了系统的python，但是环境中有pypy，这正是我们想要的。显然，如果我尝试

$ pypy
Python 2.7.13 (0e7ea4fe15e82d5124e805e2e4a37cae1a402d4b, Dec 28 2017, 20:45:53)
[PyPy 5.10.0 with GCC 7.2.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>> import numpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named numpy

它不起作用。

根据前面提到的post，我现在应该可以conda install numpy，但是这样就可以了：

conda install numpy

注意 python conda-forge/linux-64::python-3.9.2-hffdb5ce_0_cpython，因此它不会安装 numpy 到 pypy，而是安装一个新的 python3.9.

安装 numpy 后果然得到了

$ python -c "import sys; print(sys.executable)"
/home/julian/miniconda2/envs/pypy2.7/bin/python

并且 numpy 还没有为 pypy 安装。

如何让 conda install 在 pypy 而不是 python 上工作？

所有这一切都发生在 WSL (Ubuntu 18.04) 上。

Answer 1

conda不支持pypy2.7

"conda install" 没有安装到 pypy

"conda install" not installing to pypy

python

conda
