最近搞内部系统开发，频繁跟nodejs打交道，遇到了不少莫名其妙的坑，暂时记录下，回头有时间深究到底。
系统环境：
Shell
| [root@localhost ~]# lsb_release -aLSB Version: :core-4.0-amd64:core-4.0-ia32:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-ia32:printing-4.0-noarchDistributor ID: RedHatEnterpriseServerDescription: Red Hat Enterprise Linux Server release 5.8 (Tikanga)Release: 5.8Codename: Tikanga[root@localhost ~]# python -VPython 2.7.3[root@localhost ~]# node -vv0.10.26[root@localhost ~]# npm -v1.4.3 |
1，nodejs环境问题
手动编译的nodejs，流程很简单，先把Python升级了，然后下载nodejs包make install。
Shell
| # wget http://nodejs.org/dist/latest/node-v0.10.26.tar.gz# tar zxvf node-v0.10.26.tar.gz# cd node-v*# ./configure && make && make install |
过程很顺畅没有什么问题，安装完正常使用，至少node -v可以输出版本号，似乎已经成功安装了，但是在开发调试过程中发现，使用node的child_process.exec去执行一个node模块结果callback输出Error: Command failed: /usr/bin/env: node: No such file or directory，很奇怪有没有！！！代码都能执行，并且也回调了，可是回调报错竟然是node不存在。
快速解决方案：
Shell
| # ln -s /usr/local/bin/node /usr/bin/node |
2，npm link的问题
我写了一个node模块，想加入node全局调用，于是cd到模块目录npm link了下，命令正常执行，我以为一切正常，如同我在Windows下调试的那样，但是结果是：
Shell
| [root@localhost ~]# uechecker-server: No such file or directory[root@localhost ~]# which uechecker-server/usr/local/bin/uechecker-server[root@localhost ~]# ll /usr/local/bin/uechecker-server lrwxrwxrwx 2 root root 49 04-03 15:13 /usr/local/bin/uechecker-server -> ../lib/node_modules/uechecker-server/uechecker.js |
这尼玛又是什么逆天的问题，我想一定是我node没有编译好或者是系统哪里出问题了，又是各种文件不存在，暂时没有找到问题所在。
