Node.js 为什么可以'；t Travis CI是否在npm安装期间创建目录？

我最近的一次提交导致Travis CI在尝试运行

npm install

时停止工作。我唯一的改变是修改了调用Javascript文件的输入错误（从

fooBar/fooBar.js

到

fooBar/fooBar.js

），因此我不确定提交本身是否是原因。我从Travis CI收到的错误如下：

bower                                               EACCES EACCES, mkdir '/public'

EDIT3：我重新运行了以前成功的Travis构建，但它失败了，并出现了相同的错误。这让我想到，某个模块的某种更新使它不再工作。不过我不确定。也许值得注意的是，有几行代码说

优雅的fs版本3及之前的版本将在较新的节点版本上失败。请尽快更新到优雅的fs@^4.0.0。

我不知道如何更新它，因为

优雅的fs

不在

包中。提交到存储库的json

。

发现问题的根本原因是一个已更新的包，在我的环境中不再工作。我通过将我的

包中的所有版本锁定到我知道以前工作过的版本来修复它。
它是否在容器的根目录下创建了
/public
，您可能没有权限？这就是它的外观。但是为什么特拉维斯不能写它的根呢？我知道，那许可怎么会丢失呢？或者它现在正试图这样做，但之前没有这样做？尝试相对路径：
mkdir public
而不是
mkdir/public
（删除配置中产生该副作用的前导斜杠）查看日志以获得成功运行，看起来，
mkdir
确实是这个版本的新版本…@topheman我该如何更改它？My
.travis.yml
没有对
mkdir
或
/public
的任何引用。
