Question

我正在部署已在与我的prod环境相同的暂存环境中测试过的代码。代码在暂存中正确部署，但此后无法在prod中部署。我得到以下堆栈跟踪：

它抱怨的软件包没有安装在正常工作的登台服务器上，所以我不确定这是错误。（我也尝试在我的prod服务器上安装它）我很好奇是否有人知道我应该做什么。

Answer 1

您的日志消息表明您的Heroku dyno正在尝试运行命令./node_modules/.bin/_mocha。此文件不存在，因此如果无法启动，则使用Heroku进程。

Mocha是JS的测试框架，因此我不确定为什么会在生产中运行。

我会检查一些事情：

你在哪个节目中运行摩卡？是否有必要在生产中运行它？
在Procfile中，您是否意外地告诉Heroku运行摩卡？
如果你这样做，实际上需要运行mocha - 你是否已将它安装在package.json文件中？
你正在运行的mocha命令看起来不正确。通常，如果要从NPM安装中运行mocha，则可以使用命令./node_modules/mocha/bin/mocha来执行此操作。如果你完成这一步但仍然没有工作，请尝试将命令更改为我刚才列出的命令。

这应该只是涵盖每一个可能的边缘情况，以帮助你让这个东西工作！
