我在与Symfony 4.3.2一起运行的网页上发现此错误
Failed to save key "xxxx" of type array: touch(): Utime failed: Operation not permitted
但是我不知道它来自哪里，所以如果某人的潜在客户很少，我就是买家。 我不知道是否可以解决问题，但是我在Windows 10上使用ubuntu

答案 0 :(得分：1)
如果您碰巧使用FAT / FAT32或时间戳范围受到严格限制的其他文件系统，则将出现该警告。
Symfony的FilesystemCommonTrait::write()方法使用unix时间戳0调用touch()函数，以强制过期缓存的内容。 Unix时间戳0代表1970-01-01日期。根据Wikipedia，在FAT文件系统中，允许的时间戳范围是1980-01-01至2099-12-31。因此touch()函数失败并发出警告。
解决方法是在第80行附近修改FilesystemCommonTrait::write()方法。
查找行：
if (null !== $expiresAt) {
touch($this->tmp, $expiresAt);
}
在这些行之前插入：
if (0 === $expiresAt) {
$expiresAt = time() - 1;
}
这应该通过立即使缓存的内容过期而获得几乎相同的结果，但不使用无效的文件系统时间戳记。
或者，更改文件系统类型。
