无法安装pyhash模块

Question

我正在尝试安装pyhash模块，因为我一直收到一个错误。我尝试了'pip install pyhash'和'pip install pyhash==0.9.3'，但都没有成功。错误是：

Answer 1

您需要安装pypy（python的不同实现）

pyhash仅支持pypy v6.0或更新版本，请下载并安装最新的pypy

https://www.pypy.org/download.html

Answer 2

第一条错误消息

输出显示安装失败，因为安装脚本希望设置PYTHON_HOME环境变量，但实际情况并非如此

在重新运行pip install命令（在同一个shell中）之前，请尝试在shell中执行此命令：
set PYTHON_HOME=c:\users\perei\appdata\local\programs\python\python38-32

备选方案：永久设置PYTHON_HOME：

1. 打开“开始”菜单并开始键入“env”…，然后单击“编辑系统环境变量（控制面板）”
2. 单击“用户变量”下的New...
3. 在Variable name下放置“PYTHON_HOME”
4. 在Variable value下放置Python安装目录的路径，例如“c:\users\perei\appdata\local\programs\Python\python38-32”
5. 打开一个新的cmd.exe实例，然后重试pip install命令

第二条错误消息

脚本在尝试构建控制盘时失败：error: invalid command 'bdist_wheel'。在失败之前，它实际上会警告The wheel package is not available.。你只需要做pip install wheel
