pycharm安裝激活過程當中,提示 this license **** has been cancelled 。這個問題並非你的激活碼不對,而是須要修改系統的hosts文件,下面詳細講解下如何修改hosts文件。python
首先找到hosts文件所在目錄:(以windoes爲例,其餘平臺操做相似)app
Windows:C:\Windows\System32\drivers\etc\hosts編輯器
Linux:/etc/hostside
Mac:/etc/hosts字體
hosts文件並無後綴,直接是沒有辦法修改的。由於記事本只能打開txt,推薦下載任意一款代碼編輯器,推薦使用 NotePad++,使用比較簡單,而且支持多種語言。this
若是擔憂文件修改出錯,能夠先複製一份做爲備份,而後用鼠標右鍵選擇 edit with NotePad++ 或者打開 notepad++以後,直接把hosts文件拖到notepad++裏面也同樣,這樣咱們便能看到hosts文件的具體內容:spa

# Copyright (c) 1993-2009 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # be placed in the first column followed by the corresponding host name. # The IP address and the host name should be separated by at least one # space. # # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself. # 127.0.0.1 localhost # ::1 localhost |
若是想pycharm能正常使用,咱們須要在hosts文件的內容的末尾在添加一行代碼:0.0.0.0 account.jetbrains.com,注意代碼中間的空格,一個字符都不能錯,若是擔憂寫錯,請直接複製下面的代碼,而後粘貼到文件中,修改以後記得保存。

0.0.0.0 account.jetbrains.com |
不少小夥伴說修改了,可是仍是報錯 this license **** has been cancelled !在步驟完成以後,請使用notepad++從新打開檢查hosts文件,是否最後一行代碼添加成功,若是沒有this 0.0.0.0 account.jetbrains.com,只能說明你沒有修改爲功。
有時候多是C盤權限問題,你能夠直接複製一份hosts文件到桌面,修改好以後,再拷貝回去,直接覆蓋原始的hosts文件便可,這種方法最簡單(推薦)
無論是第一次安裝仍是之後再次出現這種問題,你只須要記住:this license **** has been cancelled 這個錯誤 99.99%都跟你的hosts文件有關係。
