已解决：Windows环境下PyPy安装Pip失败的问题及解决方法

在Windows系统中尝试为PyPy安装Pip时遇到问题：执行pypy3 -m pip始终提示找不到pip模块，即使运行ensurepip或get-pip.py显示安装成功后依然无法正常使用。

尝试过的操作 #

1. 查看PyPy版本：

C:\>pypy3 --version
Python 3.10.13 (fc59e61cfbff, Jan 14 2024, 16:27:58)
[PyPy 7.3.15 with MSC v.1929 64 bit (AMD64)]

2. 尝试安装tqdm，提示缺少pip：

C:\>pypy3 -m pip install tqdm
C:\Program Files (x86)\PyPy\pypy3.10-v7.3.15-win64\pypy3.exe: No module named pip (to install pip, you need to run once "C:\Program Files (x86)\PyPy\pypy3.10-v7.3.15-win64\pypy3.exe -m ensurepip")

3. 运行ensurepip安装pip：

C:\>"C:\Program Files (x86)"\PyPy\pypy3.10-v7.3.15-win64\pypy3.exe -m ensurepip

4. 再次尝试安装tqdm，依然提示缺少pip：

C:\>pypy3 -m pip install tqdm
C:\Program Files (x86)\PyPy\pypy3.10-v7.3.15-win64\pypy3.exe: No module named pip (to install pip, you need to run once "C:\Program Files (x86)\PyPy\pypy3.10-v7.3.15-win64\pypy3.exe -m ensurepip")

5. 尝试使用get-pip.py安装：

C:\Program Files (x86)\PyPy\pypy3.10-v7.3.15-win64>"C:\Program Files (x86)\PyPy\pypy3.10-v7.3.15-win64\pypy3.exe" "C:\Program Files (x86)\PyPy\pypy3.10-v7.3.15-win64\get-pip.py"

解决方法（更新） #

将PyPy移动到无空格的目录后问题解决，新路径修改为：

C:\PyPy\pypy3.10-v7.3.15-win64\

同时更新环境变量中的Path，添加上述PyPy目录路径，之后以下命令可正常运行：

>C:\PyPy\pypy3.10-v7.3.15-win64\pypy3.exe -m ensurepip
...
>pypy3 -m pip install tqdm
