当我尝试在 linux mint 18.1 的/dos 分区中创建 rails 应用程序时，它抛出以下错误

当我打开时
/home/akash/.rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/fileutils.rb：1345
第 1345 行中的代码是
def chmod(mode)
if symlink?
File.lchmod mode, path() if have_lchmod?
else
File.chmod mode, path() #1345th line
end
end
我无法理解上面的代码。请帮助我
注意：在ext4分区中创建rails应用程序工作正常。我正在使用红宝石 -2.4.0，导轨 -5.0.1
chmod(mode_int, file_name, ... )
将命名文件的权限位更改为由 mode_int 表示的位模式。 实际效果取决于操作系统。在 Unix 系统上，请参阅 chmod 了解详细信息。返回处理的文件数。
您静态授予权限
File.chmod(0604, '/path/to/file')
RBENV 安装 2.3.0
或者，您可以通过以下方式找到您可能没有写入权限的所有文件和目录
find `rbenv root`/versions ! -perm -u+w
CHMOD
