我有一个Node.js应用托管在Heroku。每次我做一个git push heroku,我得到以下错误:

错误在最后几行:

我以前把我的代码推送给Heroku没有任何问题;从星期一开始,我才出现这个错误。

我在网上看到过类似的帖子,提到的错误略有不同,但还没有看到一个![远程拒绝]master -> master(预接收钩子拒绝)之前。


当前回答

检查你的系统路径变量中是否有多个版本的npm命令。

在我的例子中,我在Node安装目录中有一个版本,在npm globals安装目录中有一个旧版本(在npm配置文件中称为prefix)。所以我检查了npm config get prefix的位置,并从node_modules中删除了链接和npm文件夹。(删除另一个也可以,这取决于PATH变量的顺序。)

其他回答

我安装了一个软件,在Users/<name>/.npmrc下生成了一个。npmrc文件

删除.npmrc文件为我解决了这个问题。

对于任何在2013年9月29日左右点击此页面的人来说,Node.js 0.10.19中有一个已关闭的错误导致了这个错误。

https://github.com/isaacs/npm/issues/2907#issuecomment-15215278 https://github.com/joyent/node/issues/6263#issuecomment-25113849

如果你在使用Heroku,你应该升级到0.10.20

"engines": {
    "node": "0.10.20"
}

我建议:改用纱线!—Yarn是一个使用相同包的包管理器。Json文件和node_modules文件夹作为npm。

对于npm,我也遇到了同样的问题:在CentOS 6安装中,我得到ERR cb()从未重复调用错误,并且无法找到一种方法让npm可靠地完成某些包的安装(例如webpack)。- Yarn工作完美无缺,即使在脆弱的网络连接上。

迁移到Yarn很容易。大多数子命令是相同的。他们有一个很好的移民指南。阅读最后方便的CLI命令比较。

似乎特定的依赖版本会导致这个问题。例如,gulp-uglifycss 1.0.7就有这个问题(参见https://github.com/rezzza/gulp-uglifycss/issues/15)。

如果您允许包中的主要或次要版本更新。通过^或~,删除文件中的这些字符,并尝试另一个NPM安装。如果它在那个时候可以工作,那么在您有了缩小导致问题的软件包的乐趣之后,您就会没事了。

从mdp留下的地方开始,问题出在节点0.10.19和npm 1.3.11上

我发现最简单的方法来管理降级,让事情顺利进行NVM,这里有一个很好的教程如何使用它。我用NVM修改了服务器环境,并在几分钟内将其从0.10.19降级到0.10.18。
