Heroku错误：解析composer.lock失败;它必须是非空的且有效的JSON [英] Heroku ERROR: Failed parsing composer.lock; it must be non-empty and valid JSON

问题描述

 目前得到这个错误并且不知道如何解决，我跑了作曲家更新，但是没有解决它。 $ git push 
抓取存储库，完成。 
计数对象：7，完成。 
使用多达8个线程的增量压缩。 
压缩对象：100％（4/4），完成。 
写入对象：100％（4/4），621字节| 0字节/秒，完成。 
共计4（delta 3），重用0（delta 0）
 
 -----> PHP应用程序检测到
 
！错误：解析composer.lock失败;它必须是非空的且有效的JSON。 
 
运行'composer update'让Composer重新生成或删除它。 
 
 
！推拒绝，未能编译PHP应用程序
 
到[e-mail]：foo.git 
！ [remote rejected] master  - > master（pre-receive hook refused）
错误：未能将某些参考文献推送到'[e-mail]：foo.git'
  

解决方案

我只是有完全相同的问题。然而，在双重检查锁定文件是有效的JSON并且是一个有效的文件。

解决方案竟然是更新作曲家本身作曲家自更新到最新版本，然后它工作正常

Currently getting this error and not sure how to fix, I ran composer update but that didn't resolve it.

$ git push
Fetching repository, done.
Counting objects: 7, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (4/4), done.
Writing objects: 100% (4/4), 621 bytes | 0 bytes/s, done.

-----> PHP app detected

!     ERROR: Failed parsing composer.lock; it must be non-empty and valid JSON.

   Run 'composer update' to have it re-generated or removed by Composer.


!     Push rejected, failed to compile PHP app

To [e-mail]:foo.git
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to '[e-mail]:foo.git'

解决方案

I just had exactly the same problem. However after double checking the lock file was valid JSON and was a valid file.

Solution turned out to be updating composer itself "composer self-update" to the latest version then it worked fine
