Imagick不会打开带有“无法读取文件”的pdf文件。例外 [英] Imagick don't open pdf files with "Failed to read the file" exception

问题描述

尝试从php脚本打开PDF文件时出现错误错误：

Trying to open PDF file from php script drop into fault with error:

Uncaught ImagickException: Failed to read the file in ...

我正在运行OS X，Brew，PHP 7.0，php70-imagick --HEAD ，ImageMagick --with-ghostscript，GhostScript

I'm running OS X, Brew, PHP 7.0, php70-imagick --HEAD, ImageMagick --with-ghostscript, GhostScript

命令行测试工作正常：

convert 1.pdf 1.jpg

文件权限正常。尝试使用带有realpath函数的URL和本地文件，因此filepath也可以。如果打开jpeg，脚本工作正常。

File permission is ok. Try both, an URL and local file with realpath function, so filepath is ok too. Script works fine if open jpeg.

phpinfo() -> ImageMagick supported formats: EPDF, PDF, PDFA, etc.

更新：已解决。解决方案如下。

UPDATE: Solved. Solution below.

推荐答案

这个问题与ghostscript的路径有关。它位于/ usr / local / bin中，但Apache无法使用此路径。 （phpinfo - > Apache Environment - > PATH）

This problem was with path to ghostscript. It's locate in "/usr/local/bin", but this path is not available to Apache. (phpinfo -> Apache Environment -> PATH)

解决方案是将符号链接文件转到另一条路径：

Solution is to symlink file to another path:

 sudo ln -s /usr/local/bin/gs /usr/bin/gs

OS X El Capitan注意！ / usr / bin /在OS X 10.11+中受到保护。您必须按照以下步骤操作：

OS X El Capitan Note! /usr/bin/ in OS X 10.11+ is protected. You have to follow this steps:

1. Reboot to Recovery Mode. Reboot and hold "Cmd + R" after start sound.
2. In Recovery Mode go to Utilities -> Terminal.
3. Run: csrutil disable
4. Reboot in Normal Mode.
5. Do the "sudo ln -s /usr/local/bin/gs /usr/bin/gs" in terminal.
6. Do the 1 and 2 step. In terminal enable back csrutil by run: csrutil enable
