Question

我正在管理一个使用Laravel 5.1和php7的遗留项目，它在CentOS中运行。

现在我正在尝试使用ubuntu 14.04和php5或带有php7的Centos在测试环境中运行它，但是我无法弄清楚为什么我在尝试运行项目时遇到此错误。

import UIKit

class FlowLayout: UICollectionViewFlowLayout {

// SET SCROLL TO HORIZONTAL
override init(){
    super.init()
    scrollDirection = .Horizontal
}

required init(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)!
    self.scrollDirection = .Horizontal
}

// SET VARIABLES: Content height/width and layout attributes
private var contentWidth: CGFloat  = 0.0
private var contentHeight: CGFloat  = 50.0
private var cache = [UICollectionViewLayoutAttributes]()


override func prepareLayout() {
    super.prepareLayout()

    // RUNS ONLY ONCE
    if cache.isEmpty {
        var row = 0
        let numberOfRows = 2
        var rowWidth = [CGFloat](count: numberOfRows, repeatedValue: 0)
        var xOffset = [CGFloat](count: numberOfRows, repeatedValue: 0)

        for item in 0 ..< collectionView!.numberOfItemsInSection(0) {
            let indexPath = NSIndexPath(forItem: item, inSection: 0)
            let tag = super.layoutAttributesForItemAtIndexPath(indexPath)
            let attributes = UICollectionViewLayoutAttributes(forCellWithIndexPath: indexPath)

            attributes.frame = tag!.frame
            attributes.frame.origin.x = xOffset[row]
            cache.append(attributes)

            rowWidth[row] = rowWidth[row] + tag!.frame.size.width + 8
            xOffset[row] = xOffset[row] + tag!.frame.size.width + 8
            row = row >= (numberOfRows - 1) ? 0 : 1
        }
        contentWidth = rowWidth.maxElement()!
    }
}

// SETS DYNAMIC WIDTH BASED ON TAGS
override func collectionViewContentSize() -> CGSize {
    return CGSize(width: contentWidth, height: contentHeight)
}

// UPDATES CELL ATTRIBUTES
override func layoutAttributesForElementsInRect(rect: CGRect) -> [UICollectionViewLayoutAttributes]? {
    var layoutAttributes = [UICollectionViewLayoutAttributes]()
    for attributes  in cache {
        if CGRectIntersectsRect(attributes.frame, rect ) {
            layoutAttributes.append(attributes)
        }
    }
    return layoutAttributes
}

override func shouldInvalidateLayoutForBoundsChange(newBounds: CGRect) -> Bool {
    return true
}


}

这可能是因为.env文件中的某个配置文件或空格中的值有错误。

如果.env文件中需要空格，请改用ENV_KEY='some value here'。
