我正在尝试通过 osx 终端中的 pear 安装 predis 并收到此错误:
$ pear install pearhub/predis
Attempting to discover channel "pearhub"...
Attempting fallback to https instead of http on channel "pearhub"...
unknown channel "pearhub" in "pearhub/predis"
invalid package name/package file "pearhub/predis"
install failed
你知道我必须做什么才能发现 pearhub 吗?
