解决 waiting for file lock on package cache lock

PS F:\rustprj\guessing_game> cargo run
    Blocking waiting for file lock on package cache

cargo build(cargo run一样的)时，出现上述问题。添加了新的依赖后，出现上述问题。然后尝试了网上的方法。确定没有多个程序占用，并且先尝试了powershell设置代理方法。并没有解决，然后删了~/.cargo/.package-cache文件后得到解决。

PS F:\rustprj\guessing_game> cd C:\Users\28328\.cargo\
PS C:\Users\28328\.cargo> ls
