react-native - -bash: react-native: 在 MAC 上找不到命令

Question

$ react-native -v

-bash：react-native：找不到命令

$ brew --version
Homebrew 2.1.0
Homebrew/homebrew-core (git revision c2b3; last commit 2019-04-14)
Homebrew/homebrew-cask (git revision 8953; last commit 2019-04-14)

$ which node
/usr/local/bin/node

$ ls -l $(which node)
lrwxr-xr-x  1 kishore  admin  31 Apr 14 11:17 /usr/local/bin/node -> ../Cellar/node/11.14.0/bin/node

$ echo $PATH

/usr/local/share/npm/bin:/usr/local/opt/sqlite/bin:/usr/local/opt/openssl/bin:/usr/local/opt/sqlite/bin:/usr/local/opt/openssl/bin:/usr/local/opt/icu4c/sbin:/usr/local/opt/icu4c/bin:/usr/local/opt/icu4c/sbin:/usr/local/opt/icu4c/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

我已经尝试了以下建议，但没有运气： react-native: command not found

找不到安装 react-native-cli 命令时出错

react-native not found + mac os

-bash：react-native：找不到命令

请帮忙，我是 React-Native 的新手。我能够构建项目，并且在 brew update 之后我被困在这个问题上并且无法进一步进行。
