无法使用nvm全局安装Express-Generator

Question

I'm using NVM to avoid using sudo to install things globally. It works fine for everything from Bower, to Grunt, etc. However, when I do npm install -g express-generator it doesnt work. For example, heres what I get when I globally install Bower:

npm install -g bower /Users/jrdillon522/.node/bin/bower -> /Users/jrdillon522/.node/lib/node_modules/bower/bin/bower bower@1.3.12 /Users/jrdillon522/.node/lib/node_modules/bower ├── is-root@1.0.0 ... ... ... ├── update-notifier@0.2.0 (semver-diff@0.1.0, string-length@0.1.2, latest-version@0.2.0, configstore@0.3.1) ├── mout@0.9.1 ├── handlebars@2.0.0 (optimist@0.3.7, uglify-js@2.3.6) ├── inquirer@0.7.1 (figures@1.3.3, mute-stream@0.0.4, through@2.3.6, readline2@0.1.0, lodash@2.4.1, cli-color@0.3.2, rx@2.3.14) └── insight@0.4.3 (object-assign@1.0.0, async@0.9.0, chalk@0.5.1, os-name@1.0.1, lodash.debounce@2.4.1, tough-cookie@0.12.1, configstore@0.3.1, inquirer@0.6.0)

Works fine right? When I install the Express Generator I get the classic error:

npm ERR! Please try running this command again as root/Administrator.

So I run sudo npm install -g express-generator . Heres what I get then:

sudo npm install -g express-generator Password: /Users/myName/.node/bin/express -> /Users/myName/.node/lib/node_modules/express-generator/bin/express express-generator@4.9.0 /Users/myName/.node/lib/node_modules/express-generator ├── mkdirp@0.5.0 (minimist@0.0.8) └── commander@1.3.2 (keypress@0.1.0) ➜ ~ express -v zsh: command not found: express ➜ ~

Why??

Answer 1

It looks like your bin path ( /Users/myName/.node/lib/node_modules/express-generator/bin/express ) isn't added to your environment.

If you modify your .bashrc file, add the following line to the bottom of your file to make things work as expected:

export PATH=$PATH:/Users/myName/.node/lib/node_modules/express-generator/bin

Then retry the installation.
