我尝试了大部分提供的解决方案，但一开始都没用。然而，事实证明，并不是解决方案失败了。显然，我的~/。Bashrc文件以以下代码块开始:

case $- in
    *i*) ;;
    *) return;;
esac

This basically is a case statement that checks the current set of options in the current shell to determine that the shell is running interactively. If the shell happens to be running interactively, then it moves on to sourcing the ~/.bashrc file. However, in a shell invoked by cron, the $- variable doesn't contain the i value which indicates interactivity. Therefore, the ~/.bashrc file never gets sourced fully. As a result, the environment variables never got set. If this happens to be your issue, feel free to comment out the block of code as follows and try again:

# case $- in
#     *i*) ;;
#     *) return;;
# esac

我希望这对你有用

对于我来说，我必须为php应用程序设置环境变量。我通过向crontab添加以下代码来解决这个问题。

$ sudo  crontab -e

定时任务:

ENVIRONMENT_VAR=production

* * * * * /home/deploy/my_app/cron/cron.doSomethingWonderful.php

在doSomethingWonderful.php我可以得到的环境值:

<?php     
echo $_SERVER['ENVIRONMENT_VAR']; # => "production"

我希望这能有所帮助!

对我来说，我必须在NodeJS文件中指定路径。

// did not work!!!!!
require('dotenv').config()

而不是

// DID WORK!!
require('dotenv').config({ path: '/full/custom/path/to/your/.env' })

在@carestad示例的基础上展开(我觉得更简单)，使用cron运行脚本，并将环境放在脚本中。

在crontab -e文件中:

SHELL=/bin/bash

*/1 * * * * $HOME/cron_job.sh

cron_job.sh文件:

#!/bin/bash
source $HOME/.bash_profile
some_other_cmd

.bash_profile源文件后面的任何命令都将拥有您的环境，就像您登录了一样。

对于这个问题，我还有一个解决方案:

0 5 * * * . $HOME/.profile; /path/to/command/to/run

在这种情况下，它将选择$HOME/中定义的所有环境变量。概要文件。

当然$HOME也没有设置，你必须用$HOME的完整路径替换它。
