我对Linux不是很熟练所以请耐心等待......
我正在尝试使用以下说明安装Node.js:
sudo apt-get update
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs=0.10.18-1chl1~precise1
可在此处找到:https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager
我运行了这些命令,在最后一个命令之后我收到了这个错误:
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help resolve the situation:
The following packages have unmet dependencies:
nodejs : Conflicts: npm
E: Unable to correct problems, you have held broken packages.
我接下来尝试运行命令sudo apt-get install nodejs,这没有给我任何错误。
但是,当我运行“npm install”时,它无法显示:
npm ERR! install Couldn't read dependencies
npm ERR! Error: ENOENT, open '/home/sarah/package.json'
npm ERR! If you need help, you may report this log at:

任何人都可以帮我弄清楚出了什么问题吗? 提前致谢

这个命令:sudo apt-get install nodejs=0.10.18-1chl1~precise1
只是一个不明智的文档。在常见用例中指定确切的版本号是错误的。所以你只使用sudo apt-get install nodejs
是正确的命令,现在一切都应该很好。
之后,看起来您已成功安装了node
和npm
(它们聚集在一起)。现在您尝试运行npm install
,它通常在节点模块的目录中运行,并查找package.json
文件。由于您的主目录不是节点模块,并且不包含package.json
文件,因此会出错。
节点安装正确,你很高兴。您可以开始使用npm init
开发新模块,或者您可以从github克隆现有模块,例如,cd到该模块的目录中,然后运行npm install
,这应该可以。
