macos - Julia Plots.gif 不以 root 身份运行时加载错误

问题描述

操作系统：Mac OS 10.14.16；朱莉娅版本：JuliaPro_v1.3.1-1

我在 Julia 中为绘图设置动画，当我不以 root 身份启动 JuliaPro 时，无法实现 Plots.gif 的所需功能。我最近克服了 JuliaPro 中的一个错误，在尝试通过调用sudo chown -R foo ~/.juliaPro. 如果我以自己的身份运行 JuliaPro，即不是 root，我会收到以下错误：

ERROR: LoadError: failed process: Process(`/Users/connorfuhrman/.juliapro/JuliaPro_v1.3.1-1/artifacts/060c5b3c7386ef4a519b0d3e45380e0b905e0bf1/bin/ffmpeg -v 0 -framerate 5 -loop 0 -i /var/folders/v1/zchgkh6j5xb77_bcw7nvk9pr0000gn/T/jl_lczuj5/%06d.png -i /var/folders/v1/zchgkh6j5xb77_bcw7nvk9pr0000gn/T/jl_lczuj5/palette.bmp -lavfi paletteuse=dither=sierra2_4a -y '{path to gif file redacted}'`, ProcessExited(1)) [1]

但是当我运行 JuliaPro 作为sudogif 正确执行时......

我试图在 ffmpeg （通过 Homebrew 安装）上放置一个符号链接，/Users/connorfuhrman/.juliapro/JuliaPro_v1.3.1-1/artifacts/060c5b3c7386ef4a519b0d3e45380e0b905e0bf1/bin/但这给出了与进程失败相同的错误。

为什么 Julia 的 Plot.gif 在以 root 身份运行时会正确执行，但在定期调用时却不能正确执行？如果我 chown-ed 相关文件夹/文件，为什么会发生这种情况？

请注意，我已经从堆栈跟踪中编辑了一些不会改变相关信息的个人信息。

解决方案

我相信我已经解决了这个问题。是一个权限问题 - 我做了一个 chmod 来解决这个问题！
