三.检查hosts文件是否修改成功 pycharm安装激活过程中提示 this license **** has been cancelled 。这个问题并不是你的激活码不对而是需要修改系统的hosts文件下面详细讲解下如何修改hosts文件。 一.找到hosts文件
首先找到hosts文件所在目录以windoes为例其他平台操作类似 WindowsC:\Windows\System32\drivers\etc\hostsLinux/etc/hostsMac/etc/hostshosts文件并没有后缀直接是没有办法修改的。因为记事本只能打开txt推荐下载任意一款代码编辑器推荐使用 NotePad使用比较简单并且支持多种语言。 如果担心文件修改出错可以先复制一份作为备份然后用鼠标右键选择 edit with NotePad 或者打开 notepad之后直接把hosts文件拖到notepad里面也一样这样我们便能看到hosts文件的具体内容
# 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二.修改hosts文件
如果想pycharm能正常使用我们需要在hosts文件的内容的末尾在添加一行代码0.0.0.0 account.jetbrains.com注意代码中间的空格一个字符都不能错如果担心写错请直接复制下面的代码然后粘贴到文件中修改之后记得保存。
0.0.0.0 account.jetbrains.com三.检查hosts文件是否修改成功
很多小伙伴说修改了但是还是报错 this license **** has been cancelled 在步骤完成之后请使用notepad重新打开检查hosts文件是否最后一行代码添加成功如果没有this 0.0.0.0 account.jetbrains.com只能说明你没有修改成功。 有时候可能是C盘权限问题你可以直接复制一份hosts文件到桌面修改好之后再拷贝回去直接覆盖原始的hosts文件即可这种方法最简单推荐 不管是第一次安装还是以后再次出现这种问题你只需要记住this license **** has been cancelled 这个错误 99.99%都跟你的hosts文件有关系。 猜你喜欢:
