composer Content-Length mismatch

用composer下包的时候，经常提示 文件大小问题。出现如下报错信息

 

composer config --global cache-files-maxsize 800MiB 

--------------

[Composer\Downloader\TransportException]

  Content-Length mismatch, received 28935 bytes out of the expected 1871484

解决办法。只需要修改默认缓存文件大小就行。亲测可用。

从默认的300 改到800.
