pip install pip

通過下面的一番實踐，pip  9.0——>18.0版本

沒錯 就是這麼簡單 = =

matplotlib去下面看吧

今天在練習《機器學習實戰》--k-近鄰演算法程式碼的過程中需要安裝 matplotlib模組，但本身電腦裡有anaconda ，不太想用，想體驗最簡單的python，所以用的Shell。

但裝anaconda對於pip就有很大問題，導致每次 pip install xxx  的時候都顯示 anaconda裡的已經存在了

但！！！我Shell用不了啊！！！

pip install --upgrade pip

python -m pip install --upgrade pip

兩種都沒辦法

最後官網找到

pip install pip

於是完美解決

以下試探過程：

看了看還是pip版本太低

嘗試了 pip install --upgrade pip 命令

emm...

You are using pip version 9.0.3, however version 18.0 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

還是 不行

於是  用一下黃字的  python -m pip install --upgrade pip

提示 anaconda裡已經有了 = =

果然需要 重新官網找地方下載 pip.whl

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

然後放到python 的Scripts 資料夾下

然後執行 

看到successfully 以為高枕無憂了

GG

最後 只能老老實實去pip官網

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

然後看到一行程式碼 = = 

沒錯就是 pip install pip

然後 完美解決 = =
