无法安装 ffmpeg 模块

Question

我正在尝试安装 ffmpeg-binaries，它可以在本地完美运行，但是当我去 hiroku 时，它开始说他找不到模块。

这是一个 Discord 机器人，运行 node.js 我试图用 npm 安装其他 ffmpeg，但只有在没有实现 ffmpeg 本身的情况下才能工作

安装节点模块（package.json + package-lock）

啊，臭名昭著的node-pre-gyp install --fallback-to-build（对您的部署失败负责）。在 mapbox/node-pre-gyp 的 Github 上，有 70 different issues 在这个确切的命令上引用错误！ node-pre-gyp 是一个非常有问题的软件包，需要安装 - 特别是在涉及跨操作系统行为时 - 所以有些解决方案可能对你有用，有些则不行。

在this issue 中，Nicolas Noble（GRPC 包的作者）指出问题是由 NodeJS 和 GRPC 的不兼容版本引起的。检查您的 NodeJS 本地版本是否与 Heroku 上运行的版本兼容，否则请检查 Heroku's guide 指定 Node 版本。

在this issue 中，用户 takase1121 的错误日志与您非常相似，如下所示：

> lzma-native@4.0.2 install [...]Node.js [...]node_modules/lzma-native
> node-pre-gyp install --fallback-to-build && rimraf build

[...]
node-pre-gyp WARN Tried to download(404): [...]
[...]

人们在本期中也提到了 ffmpeg 库，但该库仍然开放。

终于在this issue 中，用户OceanHorn 发出了（几乎）完全相同的命令！

> lzma-native@3.0.2 install /Users/OceanHorn/SourceTree/mmms/node_modules/lzma-native
> node-pre-gyp install --fallback-to-build && node node_modules/rimraf/bin.js build

[lzma-native] Success [...]

一个微小的区别：lzma-native 的版本是 3.0.2，不像你的 3.0.8 - 使用这个版本的lzma-native 可能会解决你的问题。由于只是补丁版本的不同，你应该可以使用 3.0.2 版本，而无需对代码进行任何更改。
