在树莓派上永远安装node.js / npm的问题

版本

Linux distro and version: Raspbian GNU/Linux 7 (wheezy)" Python: 2.7.3 Nodejs: v0.10.22 NPM: 1.3.15 

每次我尝试在全球范围内永远安装在我的Raspberry Pi上时，它就会失败。 错误如下所示。

同样，如果我试图做到这一点没有sudo，我得到以下几点：

 npm install forever -g npm http GET https://registry.npmjs.org/forever npm http 304 https://registry.npmjs.org/forever npm ERR! error rolling back Error: EACCES, unlink '/usr/local/lib/node_modules/forever' npm ERR! error rolling back forever@0.10.9 { [Error: EACCES, unlink '/usr/local/lib/node_modules/forever'] npm ERR! error rolling back errno: 3, npm ERR! error rolling back code: 'EACCES', npm ERR! error rolling back path: '/usr/local/lib/node_modules/forever' } npm ERR!

Answer 1

尝试使用nvm安装节点。 这会在主目录中安装节点，因此安装全局模块不需要sudo权限。 它看起来像你正在安装的模块有相关目录的问题，它可以帮助不使用sudo。

Answer 2

指定的path. 是相对于当前的工作目录，而不是相对于脚本文件。 所以，如果你运行node app.js可能会find该文件，但如果运行node folder/app.js则不会。

要创build相对于脚本的path，必须使用__dirnamevariables。

 __dirname + '/path/to/file'
