关于python的whl文件安装踩坑

安装方法反正大致就两种，下载后安装和直接安装。

一、直接安装

首先直接安装的命令（以pocketsphinx为例）（最后一个似乎是国外源，用的时候有时候会出现10054，主要还是前两个）。

pip install pocketsphinx

pip install pocketsphinx -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com

pip install pocketsphinx -i https://www.lfd.uci.edu/~gohlke/pythonlibs/ --trusted-host www.lfd.uci.edu

报错如下。

C:\Users\HUAWEI\AppData\Local\Programs\Python\Python39\Scripts>pip install pocketsphinx -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.

        常规的解决方法：：upgrade（对我来说没用）。

        然后我不信邪的安装了个别的whl（pygame）成功了，所以已知这个源可用，但是pocketsphinx不行。

        然后我就滚去下载了。

二、下载后安装

        这种方法主要问题就是注意下载版本，要和python版本统一同时和电脑操作系统的位数（32/64）统一。

        另外就是下载位置，放在当前电脑正在用的python版的Scripts中安装。

        也可以放到其他位置，安装的时候附上路径（右键 属性 安全 对象名称）。

python -v //查看python位置

pip install XXX.whl

pip install /xx/xx/xxx.whl
