The library is looking for an /usr/local/emulator folder (but it was installed in another directory). 该库正在寻找/usr/local/emulator文件夹（但它已安装在另一个目录中）。 First I checked whether the directory existed (it didn't), found where the installation directory actually was, then created a symbolic link to the actual folder location. 首先，我检查目录是否存在（不存在），找到安装目录的实际位置，然后创建指向实际文件夹位置的符号链接。 Finally, check the requested directory exists, then everything worked. 最后，检查请求的目录是否存在，然后一切正常。
ie 即
$ ls -la /usr/local/emulator
ls: /usr/local/emulator: No such file or directory
$ which emulator
/usr/local/bin/emulator
$ ls -la /usr/local/bin/emulator
lrwxr-xr-x 1 user admin 64 13 Aug 09:56 /usr/local/bin/emulator -> /usr/local/Caskroom/android-sdk/3859397,26.0.1/emulator/emulator
$ sudo ln -s /usr/local/Caskroom/android-sdk/3859397,26.0.1/emulator /usr/local/emulator
Password:
$ ls "/usr/local/bin/../emulator/qemu/darwin-x86_64/qemu-system-i386"
/usr/local/bin/../emulator/qemu/darwin-x86_64/qemu-system-i386
