【解决】brew无法安装三方库的问题：ifuse has been disabled because it requires closed-source macFUSE-CFANZ编程社区

For MAC

问题：

使用homebrew来安装ifuse等三方库，出现无法安装的提示

brew install --HEAD ifuse

Error: ifuse has been disabled because it requires closed-source macFUSE!

原因：

ifuse等三方库不再开源，FUSE底层基础软件闭源，依赖FUSE的三方库都受到影响，导致Homebrew不支持直接安装这些库了~~

从配置中可以看到受限时间：2021-04-08

  on_macos do
    disable! date: "2021-04-08", because: "requires closed-source macFUSE"
  end

解决方法：

1、修改系统时间到2021-04-08之前，再执行安装指令，如brew install ifuse，可以正常安装。（亲测无效哈哈哈😄）

但是，我修改时间后再安装，仍旧报错

meili@huangmeini ~ % brew install --HEAD ifuse

不难看出，由于系统时间变化，存在证书的问题导致其他依赖库无法安装，仍旧fail！！

2、根本解决问题：注释掉ifuse配置中的时间限制，再重新安装（该方法通用于各种三方库，如ntfs-3g、ext4fuse等等）

brew install macfuse  ##确保已经安装macFUSE
brew formula ifuse  ##获取ifuse的路径 $location_ifuse
vim $location_ifuse ##编辑ifuse的文件



注释以下段落后保存（：wq）

#  on_macos do
#    disable! date: "2021-04-08", because: "requires closed-source macFUSE"
#  end


brew install ifuse ##安装ifuse，同时配置好环境，如xcode13.2.1，success！
