时间:2024-04-05 15:44:12

pip install pip

通过下面的一番实践,pip  9.0——>18.0版本

没错 就是这么简单 = =

matplotlib去下面看吧


今天在练习《机器学习实战》--k-近邻算法代码的过程中需要安装 matplotlib模块,但本身电脑里有anaconda ,不太想用,想体验最简单的python,所以用的Shell。

但装anaconda对于pip就有很大问题,导致每次 pip install xxx  的时候都显示 anaconda里的已经存在了

但!!!我Shell用不了啊!!!

pip install --upgrade pip

python -m pip install --upgrade pip

两种都没办法

最后官网找到

pip install pip

于是完美解决


以下试探过程:

python3.6 pip升级 matplotlib安装

看了看还是pip版本太低

尝试了 pip install --upgrade pip 命令

emm...

python3.6 pip升级 matplotlib安装

还是 不行

于是  用一下黄字的  python -m pip install --upgrade pip

python3.6 pip升级 matplotlib安装

提示 anaconda里已经有了 = =

果然需要 重新官网找地方下载 pip.whl

https://www.lfd.uci.edu/~gohlke/pythonlibs/#pip

然后放到python 的Scripts 文件夹下

然后运行 

python3.6 pip升级 matplotlib安装

看到successfully 以为高枕无忧了

GG

最后 只能老老实实去pip官网

https://pypi.org/project/pip/

然后看到一行代码 = = 

python3.6 pip升级 matplotlib安装

没错就是 pip install pip
