下面是网络找的参考 看能否解决你的问题 未解决可以看看上面的

libv8 must be version 4.6.76 or greater
[V8 built with gn] configure: error: could not determine libv8 version

brew install v8@3.15
gem install libv8 -v '3.16.14.3' -- --with-system-v8
gem install therubyracer -v '0.12.3' -- --with-v8-dir=/usr/local/opt/v8@3.15
bundle install



echo 'export PATH="/usr/local/opt/v8@3.15/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc

export LDFLAGS="-L/usr/local/opt/v8@3.15/lib"
export CPPFLAGS="-I/usr/local/opt/v8@3.15/include"

export PATH="/usr/local/opt/php@7.4/bin:$PATH"
export PATH="/usr/local/opt/php@7.4/sbin:$PATH"
export LDFLAGS="-L/usr/local/opt/php@7.4/lib"
export CPPFLAGS="-I/usr/local/opt/php@7.4/include"

/usr/local/opt/php@7.4/bin/pecl install v8js

以上无效 参考下面的

Download older formula of v8 (ver 8.6.395.23):
wget https://raw.githubusercontent.com/Homebrew/homebrew-core/138b52806dad359b9f2c8da1de451b787a763944/Formula/v8.rb
Install v8 from the downloaded formula:
brew install v8.rb
If brew can't install v8 from the downloaded v8.rb file, you can try to build version 8.6.395.23 of v8 by yourself, see the guide "Compiling older version v8" above in this thread.

Make required matching phpv8js build folder structure:
mkdir -p /usr/local/Cellar/v8/8.6.395.23/libexec/lib
cp /usr/local/Cellar/v8/8.6.395.23/libexec/* /usr/local/Cellar/v8/8.6.395.23/libexec/lib
Download phpv8js:
git clone https://github.com/phpv8/v8js
cd v8js
Build phpv8js:
phpize
The following command patches file v8js_v8object_class.cc, otherwise you get 1 failed test. See 94db71e - Thanks @nvq247

sed -i -e '132s/retval/object/g' v8js_v8object_class.cc
./configure --with-v8js="/usr/local/Cellar/v8/8.6.395.23/libexec" LDFLAGS="-lstdc++" CPPFLAGS="-DV8_COMPRESS_POINTERS"
make
make test
make install
Add line extension="v8js.so" to beginning of php.in file:
php --ini
nano {path to php.ini}
brew services restart php
