Git部署未能啓動應用程序不確定原因

Question

我正在部署已在與我的產品環境相同的臨時環境中測試的代碼。代碼在分段中正確部署，但之後無法部署到產品中。我收到以下堆棧跟蹤：

它在抱怨上正常工作的臨時服務器多數民衆贊成在沒有安裝包，所以我不知道這是錯誤。 （我也嘗試在我的prod服務器上安裝它）我很好奇，如果任何人有任何想法我應該做的。

Answer 1

您的日誌消息表明您的Heroku dyno正試圖運行命令./node_modules/.bin/_mocha。這個文件不存在，所以你的Heroku進程如果無法啓動。

摩卡是JS的測試框架，所以我不知道爲什麼這將在生產中運行。

我會檢查幾件事情：

1. 你在哪裏運行在你的程序摩卡？是否有必要在生產中運行它？
2. 在您的Procfile中，您是否意外地告訴Heroku運行Mocha？
3. 如果你這樣做，其實，需要運行摩卡 - 你有它安裝在你的package.json文件？
4. 你正在運行的摩卡命令對我來說看起來不正確。通常如果你想從NPM安裝中運行摩卡，你可以使用命令./node_modules/mocha/bin/mocha來完成。如果你到了這一步，仍然沒有工作，嘗試改變你的命令到我剛剛列出的那個。

這應該只是涵蓋每一個可能的邊緣案例，以幫助你得到這個東西的工作！

祝你好運！
