我正在按照angular 官方网站的说明将 angular 6 更新为 angular 7 。
在更新会话期间：
我输入了更新 v7 的 angular/cli 和核心的命令
$ ng update @angular/cli@v7 @angular/core@v7。
更新后我得到了Invalid rule result: Function().
这是命令提示符输出：
added 106 packages from 85 contributors, removed 5 packages, updated 5 packages, moved 1 package and audited 36489 packages in 39.604s
found 18 vulnerabilities (12 low, 1 moderate, 5 high)
run `npm audit fix` to fix them, or `npm audit` for details
Invalid rule result: Function().
有谁知道我为什么收到消息？
这是package.json文件中的依赖项。
"dependencies": …将 angular 7 更新为 angular 8，我angular/cli angular/core使用命令成功更新$ ng update @angular/cli@v8 @angular/core@v8。而且我也使用了有角度的材料，所以我想更新材料，然后我用$ ng update @angular/material@v8. 但是在运行命令后我得到了Repository is not clean. Please commit or stash any changes before updating.
所以我在更改 git 之前提交，然后我再次尝试使用相同的命令，然后也得到相同的消息。现在没有要提交或存储的文件。
这是package.json文件的依赖关系：
