提问by azero0
I am getting a
我得到一个
forever: command not founderror when I run a nodejs process using the forever command as a cronjob (in an amazon ec2 machine): the bash script I am using has the following code:
永远：当我使用forever命令作为cronjob（在亚马逊ec2机器中）运行nodejs进程时，命令未找到错误：我使用的bash脚本具有以下代码：
cd to/location/of/the/nodejs/file
cd 到/location/of/the/nodejs/file
forever start file.js
永远开始 file.js
but I am able to run this file by using bash script.sh but I get the forever:command not found error when I run it via cronjob
但是我可以使用 bash script.sh 运行这个文件，但是当我通过 cronjob 运行它时，我得到了永远：找不到命令的错误
I am confused dont know what could be the reason for this.
我很困惑不知道这可能是什么原因。

Run this command: npm install forever -g
运行此命令： npm install forever -g
-gis to install it globally.
-g是全局安装。

For other users who face this problem:
对于遇到此问题的其他用户：
you have to add the path of forever module and then run the script as a cronjob.
您必须添加forever 模块的路径，然后将脚本作为cronjob 运行。
In linux the path normally is:
在linux中，路径通常是：
/usr/local/lib/node_modules/forever/bin/forever start file.js
/usr/local/lib/node_modules/forever/bin/forever start file.js
just use this command in your script and the error forever:command not foundwill not bother you.
只需在您的脚本中使用此命令，错误永远：找不到命令不会打扰您。
I know there must be some other fancy ways to do this but I am happy with this hack
我知道一定有其他一些奇特的方法可以做到这一点，但我对这个 hack 很满意

If you have already tried:
如果您已经尝试过：
sudo npm install forever -g
and still get forever:command not foundpay attention to the first line in the output. This should be something like:
并且仍然forever:command not found注意输出中的第一行。这应该是这样的：
/<node_bin_path>/forever -> /lib/node_modules/forever/bin/forever
where node_bin_pathis the place in which the executable is located. This is most likely not where you expect.
wherenode_bin_path是可执行文件所在的位置。这很可能不是您所期望的。
This may be because nodein your path is a symbolic link. In this case foreverwill be installed in the actual install location of nodenot the location of the symbolic link.
这可能是因为node在您的路径中是一个符号链接。在这种情况下forever将安装在实际安装位置而node不是符号链接的位置。
