尝试在 Lion 上从 Foreman 运行 Node 时出现问题 - “exec”：权限被拒绝错误

Question

我按照 Heroku 网站上的指南使用 foreman 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，但是一旦我在Procfile中使用Foreman，就会出现以下错误......

有什么问题吗？我能做的就是给福尔曼 允许？我尝试过 sudo foreman start ，但没有成功。

我正在 ruby​​ 版本 1.9.3 中运行（从默认安装在 lion 上的版本 1.8.7 升级）。

更新

在@user658619从ruby gems安装heruko和foreman之后运行sudo foreman start，我们得到...

Answer 1

我今天也遇到了同样的问题。你是通过heroku-toolbelt.pkg安装heroku的吗？

尝试使用 gem 重新安装 heroku 和 foreman。

sudo gem install heroku foreman

Answer 2

基本上，为了让它工作，我不幸地混合了红宝石和宝石，搞砸了我的安装，其中一些需要 SUDO，一些则不需要。

幸运的是，互联网上的好心人已经用一个名为 RVM 的工具为您解决了这个问题

RVM 允许您使用自己的完全独立且专用的环境来部署每个项目 - 从特定版本的 ruby​​，一直到运行应用程序所需的一组精确的 gem。拥有一套精确的 gems 还可以避免项目之间的版本冲突问题，这可能会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)

您需要打开一个新的执行此操作后的终端窗口。

清理。如果您安装了奇怪的宝石，您会想要将其删除。转到根目录并 sudo 删除它们。您可以使用gem list 命令

cd 
sudo gem list
sudo gem uninstall foreman heroku

安装 ruby​​ 查看所有这些。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，这只是工头和 Heroku。

cd myApp
gem install foreman heroku

似乎工作很愉快。

试试这个。在 Procfile 中，执行

web: node ./bin/www
