无法使用 npm 重建依赖项

Question

当我试图将在本地运行良好的 nodejs 应用程序推送到 heroku 时，这是我在终端中得到的：

这是我的 package.json 文件：

  "version": "0.0.1",
  "dependencies": {
    "dnode": "1.0.5",
    "shoe": "0.0.10"
  },
  "engines": {
    "node": "0.10.x",
    "npm": "1.2.x"
  }
}

有什么想法吗？

Answer 1

所以rbytes 包已经有 2 年没有改变了，并且在那段时间节点已经从node-waf 构建系统切换到node-gyp。从节点 v0.10.0 开始，不再包含 node-waf，因此出现 sh: node-waf: not found 错误消息。我认为你有几个选择（按优先顺序）：

1. 使用更现代的模块而不是 rbytes
2. 说服rbytes的作者更新以支持最新节点并发布新版本
3. 分叉 rbytes 并自行修复
4. 将您的 package.json 引擎设置为节点 0.8，然后重试

嗯，错误消息 #2 看起来仍然没有正确构建 rbytes。我必须深入研究该软件包以了解该错误。不确定它如何/为什么在本地为您工作，但在 heroku 上遇到问题，但我认为是时候让 rbytes 维护者进行一些维护了。

Answer 2

在 Ubuntu 中重新编译最新版本的 node.js 后，我遇到了这个问题。根据 Peter Lyon 的建议，这个问题与 node-gyp 不存在有关。通常，从预编译包安装时，这不是问题（aptitude 和 rhel 存储库通常默认包含 node-gyp）。

但是，如果您是从源代码构建，则很可能 node-gyp 不存在，这就是导致我的问题的原因。

这为我解决了：

sudo npm install -g node-gyp

之后，运行 npm install 工作正常，错误消失了！

Answer 3

远离 rbytes，一般来说远离任何未维护的模块，尤其是做一些重要而微妙的事情的模块，比如加密。您可以使用 Node 的本机加密模块获得所需的一切。见http://nodejs.org/api/crypto.html#crypto_crypto_randombytes_size_callback：

crypto.pseudoRandomBytes(256)

Answer 4

我遇到了同样的问题，只需删除现有的 node_module 目录。然后运行 ​​npm 安装。就是这样
