You normally use a tool like pipto install wheels. Leave it to the tool to discover and download the file if this is for a project hosted on PyPI.
您通常使用诸如pip安装轮子之类的工具。如果这是用于 PyPI 上托管的项目，则将其留给工具来发现和下载文件。
For this to work, you do need to install the wheelpackage:
为此，您需要安装wheel软件包：
pip install wheel
You can then tell pipto install the project (and it'll download the wheel if available), or the wheel file directly:
然后，您可以告诉pip安装项目（如果可用，它将下载轮子）或直接安装轮子文件：
pip install project_name # discover, download and install
pip install wheel_file.whl # directly install the wheel
The wheelmodule, once installed, also is runnable from the command line, you can use this to install already-downloaded wheels:
该wheel模块一旦安装，也可以从命令行运行，您可以使用它来安装已经下载的轮子：
python -m wheel install wheel_file.whl
Also see the wheelproject documentation.
另请参阅wheel项目文档。

If you already have a wheel file (.whl) on your pc, then just go with the following code:
如果您的电脑上已经有一个轮文件 (.whl)，那么只需使用以下代码：
cd ../user
pip install file.whl
If you want to download a file from web, and then install it, go with the following in command line:
如果要从 Web 下载文件，然后安装它，请在命令行中执行以下操作：
pip install package_name
or, if you have the url:
或者，如果您有网址：
pip install http//websiteurl.com/filename.whl
This will for sure install the required file.
这肯定会安装所需的文件。
Note: I had to type pip2 instead of pip while using Python 2.
注意：在使用 Python 2 时，我必须输入 pip2 而不是 pip。
