如何在Travis CI上安装uglify-js？

我的版本在Travis CI上失败，因为uglify-js将不会安装。输出日志的相关部分如下。我正在安装nodejs和npm，因为这是一个language: cpp构建而不是language: node_js构建（其C++库与其他语言的绑定，包括一些客户端JavaScript需要缩小）。如何在Travis CI上安装uglify-js？

根据http://docs.travis-ci.com/user/ci-environment/#Runtimes'nodejs'（和'npm'？）应该已经安装。但是当我删除上面的apt-get行时，我得到了'sudo：npm：command not found'。 – nokome

嗨，我只是尝试了一个简单的[.travis.yml]（https://github.com/cotsog/travisci_nodejs/blob/master/.travis.yml）文件，它似乎工作，而不必安装'npm'事先通过'apt-get'。这是我的[生成日志]（https://travis-ci.org/cotsog/travisci_nodejs/builds/64033106）。（即使构建失败，日志显示我可以成功调用uglifyjs。）您能否提供.travis.yml文件？ –

在进一步的测试，你需要运行npm不sudo解决您的问题。这样您就不需要事先拨打apt-get。

非常感谢您的帮助。这工作和解决了构建（虽然它仍然在我写的后续任务）：https：//travis-ci.org/stencila/stencila – nokome
