-bash express: command not found

问题:

I am getting a very odd error trying to install the express-generator with and without sudo.

I need to run: npm install express-generator -g and then express --ejs name_here but when executing the first command, I get the following error:

npm ERR! Darwin 15.2.0 npm ERR! argv "node" "/usr/local/bin/npm" "install" "express-generator" "-g" npm ERR! node v0.12.7 npm ERR! npm  v2.11.3 npm ERR! path /Users/[name]/.npm/lib/node_modules/express-generator/LICENSE npm ERR! code EACCES npm ERR! errno -13  npm ERR!

Please include the following file with any support request: npm ERR!     /Users/[name]/Documents/Projects/MEAN Stack Tutorial/npm-debug.log 

After trying sudo npm install express-generator -g I get this:

/Users/[name]/.npm/bin/express -> /Users/[name]/.npm/lib/node_modules/express-generator/bin/express express-generator@4.13.1 /Users/[name]/.npm/lib/node_modules/express-generator ├―― sorted-object@1.0.0 ├―― commander@2.7.1 (graceful-readlink@1.0.1) └―― mkdirp@0.5.1 (minimist@0.0.8) 

Then running express --ejs name_here returns -bash: express: command not found

Is there a way I can solve this issue? The other questions on SO seem to have fixed the issue by trying sudo but not for me.

回答1:

Try to use an express command with a full path: /Users/[name]/.npm/bin/express or sudo /Users/[name]/.npm/bin/express.

Looks like PATH variable wasn't set after installation. (https://en.wikipedia.org/wiki/PATH_(variable))
