关于node.js：如何在Python virtualenv中安装lessc和nodejs？

How to install lessc and nodejs in a Python virtualenv?

我想将nodejs脚本(lessc)安装到virtualenv中。

我该怎么做？

谢谢

我喜欢Shorrty的回答，他建议使用nodeenv，请参阅：
node.js是否有虚拟环境？

我遵循了该指南：
http://calvinx.com/2013/07/11/python-virtualenv-with-node-environment-via-nodeenv/

我要做的就是：

1

. ../bin/activate # switch to my Python virtualenv first
pip install nodeenv # then install nodeenv (nodeenv==0.7.1 was installed)
nodeenv --python-virtualenv # Use current python virtualenv
npm install -g less # install lessc in the virtualenv

这是我到目前为止使用的，但是我认为它可能已经过优化。

安装nodejs

wget http://nodejs.org/dist/v0.6.8/node-v0.6.8.tar.gz
tar zxf node-v0.6.8.tar.gz
cd node-v0.6.8/
./configure --prefix=/absolute/path/to/the/virtualenv/
make
make install

安装npm(节点程序包管理器)

1 2	/absolute/path/to/the/virtualenv/bin/activate curl https://npmjs.org/install.sh \| sh

安装lesscss

1	npm install less -g

激活virtualenv时，可以使用lessc

我创建了一个bash脚本来自动化Natim的解决方案。

确保您的Python virtualenv处于活动状态，然后运行脚本。 NodeJS，NPM和lessc将被下载并安装到您的virtualenv中。
