背景：
最近搗鼓python，IDE用的是VS code，可是一直沒把環境整好。
今天VS提示pylint沒裝，我就點安裝呀，這算事麼？不要讓我分心呀。。。果斷點了install
問題：
不出意料，結果失敗了。
反覆試了幾次，還是不行，仔細看看提示吧。
大概，我估摸應該就是證書驗證那塊沒過去，https這個安全連接搞不起來，具體啥原因呢？
有的說是新版本python的問題，我就按照方法，取消了安全驗證，沒啥用，結果一模一樣。
那我更傾向於是其他問題了，但我沒有深究結果。
因爲我的目的是要把pylint搞定。
咋整呢？
解決方案：
只能手動了的說！
按照錯誤提示，比如：
Could not fetch URL https://pypi.org/simple/mccabe/
就連不上唄，下載不下來唄，它不行，我來唄。
解決步驟：
1.複製連接到瀏覽器，手動打開連接，比如：https://pypi.org/simple/mccabe/，如下圖：
2.果斷下載最新的.whl文件（.gz應該也可以，試過wrapt的gz，可以用pip安裝），我下載之後放在pyhton安裝目錄下的scripts文件夾裏了。
不瞞你們說，下了不少。。。（一句命令的事，手動真累呀！）
3.在存放這些文件的目錄下，打開cmd，用pip安裝。
以上面的文件爲例，命令是：pip install mccabe-0.6.1-py2.py3-none-any.whl，然後回車。
4.回車之後兩種結果，要麼success，要麼給你個連接打不開提示，那你就繼續複製連接到瀏覽器，下載最新文件，再次安裝。
5.直到滿足所有pylint需要的條件，再安裝它！就成功了！（相當野蠻和暴力了。。。。）
資源分享：
下面把我打開的連接都貼上來，需要什麼文件，可以去連接找，資源名就是連接最後一個單詞。
https://pypi.org/simple/pylint/
https://pypi.org/simple/isort/
https://pypi.org/simple/astroid/
https://pypi.tuna.tsinghua.edu.cn/simple/
https://pypi.org/simple/lazy-object-proxy/
https://pypi.org/simple/wrapt/
https://pypi.org/simple/colorama/
https://pypi.org/simple/mccabe/
還要插一句，大家電腦環境不一樣，俺也不知道你們裝了啥，缺了啥，需要啥，能幫上就看看，方法可以互相學習。
最後，把我的cmd過程貼上來。
