我已使用npm-g_nosudo脚本在我的Yosemite安装上安装了var fs = require('fs');
var filename = './80.json';
var bufferString;
function ReadFile(callback) {
fs.readFile(filename, 'utf-8', function(err, data) {
bufferString = data;
callback();
});
}
function PrintLine() {
console.log(JSON.parse(bufferString));
}
ReadFile(PrintLine)
并设置了node.js。然后，当我运行npm时，我看到一堆内容滚动到我的终端窗口，没有错误，它就完成了。然后我输入npm install -g yo，OS X告诉我它无法找到命令。
yo我也尝试使用Sullys-MacBook-Pro:~ Sully$ npm install -g yo

Running sanity checks on your system
✔ Global configuration file is valid
✔ NODE_PATH matches the npm root
✔ No .bowerrc file in home directory
✔ No .yo-rc.json file in home directory
Everything looks all right!

这是我的source .bash_profile

通过将~/.bash_profile添加到Terminal.app并重新启动$newIm='test.png';<br>
if(exif_imagetype($newIm)==IMAGETYPE_PNG) {<br>
$file_type="PNG";<br>
}elseif (exif_imagetype($newIm) ==IMAGETYPE_JPEG) {<br>
$file_type="JPG";<br>
}<br>
$pdf->Image($newIm,null,null,150,100,$file_type);<br>来解决此问题。

在成功安装所有内容后，我遇到了同样的问题，我使用以下方法解决了这个问题，创建了符合以下条件的yo，grunt，bower的符号链接：
对于Yo
praveen@praveen-lenovo:~$ sudo ln -s /home/praveen/.npm-global/bin/yo /usr/bin/yo
对于Grunt
praveen@praveen-lenovo:~$ sudo ln -s /home/praveen/.npm-global/bin/grunt /usr/bin/grunt
对于Bower
praveen@praveen-lenovo:~$ sudo ln -s /home/praveen/.npm-global/bin/bower /usr/bin/bower
在上面的命令中，公共路径/home/praveen/.npm-global/bin/可能会根据您的系统文件夹结构而改变。
