尝试从Lion上的Foreman运行Node时出现问题 - “exec＆＃39;”权限被拒绝错误

标签： ruby node.js heroku osx-lion foreman

我已经按照Heroku网站上的指南来使用工头运行节点服务器：

http://devcenter.heroku.com/articles/node-js

如果我直接加载它，我可以成功启动节点服务器，但是只要我在Procfile中使用Foreman，就会出现以下错误...

我有什么办法可以给予Forman许可吗？我试过sudo foreman start，但无济于事。

我在ruby版本1.9.3中运行（默认情况下从Lion上安装的1.8.7版本升级）。

更新

在sudo foreman start从红宝石宝石安装heruko和工头后运行@user658619，我们得到......

我今天遇到了同样的问题。您是否通过heroku-toolbelt.pkg安装了heroku？

尝试使用gem重新安装heroku和foreman。

sudo gem install heroku foreman

基本上为了让它工作，我不幸地把我的装置弄得乱七八糟地混合了红宝石和宝石，其中一些需要SUDO，有些则不需要。

幸运的是，互联网的优秀人员使用名为RVM的工具

为您解决了这个问题
  

RVM允许您使用自己完全独立的专用环境部署每个项目 - 从特定版本的ruby，一直到运行应用程序所需的精确宝石集。拥有一组精确的宝石还可以避免项目之间的版本冲突问题，这可能导致难以追踪的错误和数小时的脱发。

http://beginrescueend.com/

首先下载RVM 

$ bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)

执行此操作后，您将需要打开一个新的终端窗口。

清理。如果你有奇怪的安装宝石，你会想要删除它们。转到你的根目录，sudo摆脱它们。您可以使用gem list命令

查看所有这些内容 
cd 
sudo gem list
sudo gem uninstall foreman heroku

安装ruby。您应该在应用程序的子目录中执行此操作。我选择了1.9.3 

cd myApp
rvm install 1.9.3

添加您需要的任何宝石。对我来说只是工头和牧人。

cd myApp
gem install foreman heroku

似乎是一种享受。

试试这个。在Procfile中，执行

web: node ./bin/www
