Pip 不工作，说它不能造轮子

Question

我在网上寻找解决方案，但没有找到。

我有一台新电脑，这是我拥有的第一台桌面，我需要为高中项目安装 python 和 pip 以及所有这些东西，但是在安装 PyTorch 和其他我需要的软件包时，我遇到了这个错误：

请注意，您的错误是由c:\program files\inkscape\bin\python.exe 引起的，几乎可以肯定完全是错误的 python 可执行文件，因为这不是 python 自身安装的位置。

卸载你安装的任何东西，然后从https://www.python.org/downloads/windows/ 获取最新的安装程序，运行它（使用管理员权限，因为希望你记得确保你自己的帐户设置为正常帐户类型并且不是管理员帐户，出于明显的安全原因），然后在完成安装后，请确保更新您的 PATH：

• 运行“高级系统设置”
• 点击“环境变量”按钮
• 双击“系统变量”部分中的PATH 条目
• 确认C:\Program Files\Python38\ 和C:\Program Files\Python38\Scripts\ 都在其中。如果没有，请添加它们。 （当然也可以是您自定义安装它们的任何位置）。
• 可能需要：还要检查您的路径中是否有 Inkscape 条目。如果有，请使用“上移”/“下移”按钮确保 Python 条目列在 Inkscape 条目的上方。

然后您可以使用管理员权限启动 cmd/powershell/etc（如果您已经打开了一个，请关闭它并启动一个新的以使更新的 PATH 生效），然后使用pip（不是pip3 ) 全局安装包。

也就是说，对于您几乎总是希望使用 python 的“virtualenv”概念的项目，在 https://docs.python.org/3/tutorial/venv.html 上进行了解释，它允许您在本地安装依赖项，这意味着如果一个项目需要 Django 2.10 而另一个需要 Djangoo 3.0，他们每个人都安装在自己的虚拟环境中，而不是引起全局依赖冲突。

最后，我最终使用了 anaconda，它成功了。非常感谢，但是设置这些东西会让我发疯，而且我可能没有能力理解很多说明......
