MacOS下PHP7.1升級到PHP7.4.15的方法

最近寫SDK的時候需要用到object型別提示符,phpStorm智慧提示說需要PHP7.2以上才能支援這種型別提示。
我一查我本機的PHP是7.1.30版本,於是考慮升級一下PHP版本。
首先要嘗試使用如下命令進行升級:

brew update 
brew upgrade [email protected]

第一個遇到的報錯如下所示:

git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshal程式設計客棧low
This restriction has been made on GitHub's request because updating shallow

clones is an extremely expensive operation due to the tree layout and traffic of
Homebrew/homebrew-core and Homebrew/homebrew-cask. We don't do 程式設計客棧this for you
automatically to avoid repeatedly performing an expensive unshallow operation in
CI systems (which should instead be fixed to not use shallow clones). Sorry for
the inconvenience!

然後按照提醒執行"git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow"命令還會報錯:

fatal: dumb http transport does not support shallow capabilities

由此懷疑homebrew-core的源可能因為一些不可抗力的原因無法正常使用,從而導致fetch操作失敗。可以考慮換成國內的源,編寫shell如下所示:

# 切換到homebrew-core目錄下
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
# 設定homebrew源為國內的中科大映象
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
# 更新homebrew-core
git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow

執行之後可以看到如下輸出,然後就可以順利執行brew update了。

remote: Enumerating objects: 539863,done.
remote: Counting objects: 100% (539826/539826),done.
remote: Compressing objects: 100% (194417/194417),done.
remote: Total 530481 (delta 341532),reused 521981 (delta 333211)
Receiving objects: 100% (530481/530481),191.29 MiB | 9.18 MiB/s,done.
Resolving deltas: 100% (341532/341532),completed with 8120 local objects.

安裝php7.4的方法很簡單,可以使用原始碼下http://www.cppcns.com載編譯的方法:

brew install --build-from-source [email protected]

可以看到大量輸出,最後沒有報錯就可以完成php7.4的安裝啦。

要讓終端裡面之前的PHP版本切換成功還需要在.bash_profile中設定環境變數,新增如下語句:

export PATH="/usr/local/opt/[email protected]/bin:$PATH"
export PATH=/usr/local/opt/[email protected]/sbin:$PATH

最後執行source ~/.bash_profile命令完成生效操作。

為了確認是否真的生效,可以執行如下命令php -v
得到輸出如下即為正確:
