切换到目录时出错：“perl版本5.12.3无法运行/ usr / bin / shasum”

Question

我安装了rvm 1.9.3，现在每当我切换到包含.rvmrc的目录时，都会收到一条perl错误消息：

~/example$ cd .. && cd example

perl version 5.12.3 can't run /usr/bin/shasum.  Try the alternative(s):

/usr/bin/shasum5.10.0 (uses perl 5.10.0)

Run "man perl" for more information about multiple version support in
Mac OS X.

Answer 1

您可以尝试这种肮脏的方法。这种方法将跳过这些检查并直接在二进制目录中使用shasum

$ cd /usr/bin
$ ls shasum*
  shasum shasum5.10.0
$ mv /usr/bin/shasum /usr/bin/your_backup_shasum
$ ln -s shasum5.10.0 shasum
