Unity更新插件提示后the same name nunit.framework unity项目一直不能运行

Posted 2023-03-10 avi9111

最近在做一个旧项目，是Unity5，没法升级，但是因为加了一些pack，就死活compile出错了

是C#代码（内部）出错，项目一直跑不起来了

出错的提示是很怪，说unit.framework重复了，这个框架本是C#框架，和unity关系不大，

没法用常规方法定位

未必完全是下面的错误提示，但问题是一样的，都是更新包后莫名出错了

方法一：

工作多年居然不知道解决方法是：有查看update log的方法，特别是下面第二个方法，很好用

我查到的log如下

=== Sun Jan  8 01:52:25 2023

Packages were changed.

The following packages were added:

网上找的错误提示

===================================

PrecompiledAssemblyException: Multiple precompiled assemblies with the same name Mono.Cecil.dll included for the current platform. Only one assembly with the same name is allowed per platform. Assembly path: 0

======================================================

解决方案如下

1：打开packages manager ，在window->packages Manager。然后把能升级的package 都升级了。应该就解决了

如果找不到Packages Manager

2: (1) 打开项目目录下的 Logs->Packages-Update.log。 看看都更新了什么package。

(2) 打开项目目录下的Packages->manifest.json。 备份里面的内容，然后删除unity升级时加的package。

(3)重启unity，这个时候错误应该消失了。

(4)打开packages manager ，在window->packages Manager。然后把能升级的package 都升级了。

(5)把第二部删除的package添加回来

(6)重启unity

方法二：

直接看log的实体。。。。。。。。。。。。。。

发现又是Packagecache的问题（为什么用又呢？）
