如何为nodejs设置节点路径(Ubuntu)

Question

我正在尝试设置nodejs来访问postgres数据库.到目前为止我所做的是以下内容(https://gist.github.com/579814):

echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc
. ~/.bashrc
mkdir ~/local
mkdir ~/node-latest-install
cd ~/node-latest-install
curl http://nodejs.org/dist/node-latest.tar.gz | tar xz --strip-components=1
./configure --prefix=~/local
make install # ok, fine, this step probably takes more than 30 seconds...
curl http://npmjs.org/install.sh | sh

然后

git clone git://github.com/isaacs/npm.git
make
make install

到现在为止还挺好.但是,当我尝试安装postgres驱动程序时

npm install pg

我得到以下内容:

我一直在寻找设置节点路径,虽然到目前为止还没有找到任何帮助 - 可能也因为我对nodejs全新,所以我会对任何提示感到高兴.

Answer 1

现在,您已在Ubuntu中安装了NodeJS.您应该设置/etc/environment并加载可由其他用户执行的nodeJS路径.例如:

NODE="/home/ubuntu/local/node"
NODE_PATH="/usr/local/lib/node_modules" 
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:$NODE/bin:$NODE/lib/node_modules"
#PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"

Answer 2

在bash中执行此操作:echo 'export NODE_PATH=~/local/:~/local/node_modules' >> ~/.bashrc
