Question

更新+2小时：

我重新启动，卸载，然后安装了下载的Railsinstaller程序的新副本。

将宝石大理石拉下来并安装好。说它安装正确。（但是，我想我在某些地方读到只有宝石名称就足够了，宝石安装名称是多余的。）

启动服务器 - 同样的问题。运行时JS并不存在。

所以我创建了一个新的应用程序。构建经历了干净。再次安装了execjs。（正确安装）。奔跑的导轨s＆＃39;并且同样的问题仍然存在。

找不到解决方案。

我是一个绝对的新手。步骤顺序：

以传统方式安装Ruby。从Ruby网站下载，安装，尝试使其工作。出了点问题 - BUNDLE INSTALL表示无法找到宝石文件。

我说没问题 - 让我们寻找答案......

我安装了Railsinstaller作为完整包。安装进展顺利。我甚至创建了一个名为＆＃39; my_app＆＃39;的新虚拟应用程序。

是的......

然后我使用应用程序导航到目录并打了一拳#s; s＆＃39;在命令提示符下（顺便说一下，以管理员身份运行）

服务器已启动（WEBrick）。我去localhost：3000并没有显示。我去提示并做gem安装rails 它可以获取一些宝石并做更多的工作

现在当我启动服务器时 - 它会抛出一些关于Javascript的错误。

这是错误：

我不知道下一步该做什么。请帮忙......

Answer 1

在你的Gem文件中，写下

gem 'therubyracer'
gem 'execjs'

然后运行

bundle install
