错误在macOS上安装Composer(JIT编译失败)

Question

当我composer --version在macOS终端中运行时,我收到以下错误:

Answer 1

这是一个已知的PHP 7.3 错误.

作为临时修复,编辑您的php.ini文件(在我的情况下vi /usr/local/etc/php/7.3/php.ini:),通过更改以下命令禁用PHP PCRE JIT编译:

;pcre.jit=1

至

pcre.jit=0

Answer 2

我通过禁用PCRE jit编译解决了这个问题.

我想你通过自制软件安装了php 7.3.

如果是zzz-myphp.ini,请/usr/local/etc/php/7.3/conf.d使用以下内容创建一个in :

; My php.ini settings
; Fix for PCRE "JIT compilation failed" error
[Pcre]
pcre.jit=0

Answer 3

其他答案建议通过配置文件禁用PCRE JIT.这有效,但需要注意:这会禁用所有使用这些INI文件的引擎调用的PCRE JIT .因此,您可能无法获得JIT改进的潜在更广泛的功能,这可能是不可取的.

您composer只能通过以下方式禁用JIT :

php -d pcre.jit=0 composer.phar ...
