 ### OpenSSL
 Monterey中openssl的安装位置可能不再位于`/usr/local/opt/openssl`，很可能会在`/opt/homebrew/Cellar`目录下，如果编译时报告找不到openssl：
 
-* 先运行`brew link openssl --force`看看`/user/local/opt/openssl`是否出现了
+* 先运行`brew link openssl --force`看看`/usr/local/opt/openssl`是否出现了
 * 没有的话可以自行设置软链：`sudo ln -s /opt/homebrew/Cellar/openssl@3/3.0.3 /usr/local/opt/openssl`。请注意此命令中openssl的目录可能随环境变化而变化，可通过`brew info openssl`查看。

 openssl installed in Monterey may not be found at `/usr/local/opt/openssl`, instead it's probably put under `/opt/homebrew/Cellar`. If the compiler cannot find openssl：

Note that the installed openssl in above command may be put in different places in different environments, which could be revealed by running `brew info openssl`.
