如何直接從GitHub安裝NPM軟件包？試圖從GitHub安裝模塊會導致：在Package.json上出現(xiàn)錯誤。使用快件容易復制：npm install https://github.com/visionmedia/express拋錯。npm install express起作用了。為什么我不能從GitHub安裝？以下是控制臺輸出：npm http GET https://github.com/visionmedia/express.git npm http 200 https://github.com/visionmedia/express.git npm ERR! not a package /home/guym/tmp/npm-32312/1373176518024-0.6586997057311237/tmp.tgz npm ERR! Error: ENOENT, open '/home/guym/tmp/npm-32312/1373176518024-0.6586997057311237/package/package.json' npm ERR! If you need help, you may report this log at: npm ERR!     <http://github.com/isaacs/npm/issues> npm ERR! or email it to: npm ERR!     <npm-@googlegroups.com> npm ERR! System Linux 3.8.0-23-generic npm ERR! command "/usr/bin/node" "/usr/bin/npm" "install" "https://github.com/visionmedia/express.git" npm ERR! cwd /home/guym/dev_env/projects_GIT/proj/somename npm ERR! node -v v0.10.10 npm ERR! npm -v 1.2.25 npm ERR! path /home/guym/tmp/npm-32312/1373176518024-0.6586997057311237/package/package.json npm ERR! code ENOENT npm ERR! errno 34 npm ERR!  npm ERR! Additional logging details can be found in: npm ERR!     /home/guym/dev_env/projects_GIT/proj/somename/npm-debug.log npm ERR! not ok code 0
