問題描述

我正在使用 gulp-nodemon

config 目錄只包含一個文件 server.js.

config directory includes only one file, server.js.

$.nodemon({
  script: 'config/server.js',
  watch: ['config/**/*.js']
})
.on('restart', function () {
  setTimeout(function () {
    $.livereload.changed();
   }, 1000);
 });

輸出:

[gulp] [nodemon] v1.2.1
[gulp] [nodemon] to restart at any time, enter `rs`
[gulp] [nodemon] watching: config/**/*.js
[gulp] [nodemon] starting `node config/server.js`
[gulp] [nodemon] watching 34,325 files - this might cause high cpu usage. To reduce use "--watch".

如果我包含一個忽略選項，它會修復.

If i include an ignore option it fixes.

ignore: [
  'node_modules/**',
  'bower_components/**'
]

即使我告訴它只看配置目錄，為什么 nodemon 還要看一切?

Why does nodemon watch everything even when I tell it to watch only config directory?

從輸出中也可以看出，它只監視配置目錄 [nodemon] 監視:config/**/*.js

Also it appears from the output it only watches the config directory [nodemon] watching: config/**/*.js

推薦答案

這似乎是 nodemon 的錯誤 本身，因為我能夠使用簡單的 nodemon 命令重現它:

This seems to be a bug with nodemon itself, because I was able to reproduce it using the simple nodemon command :

> nodemon --watch app server.js
[nodemon] v1.2.1
[nodemon] to restart at any time, enter `rs`
[nodemon] watching: app/**/*
[nodemon] starting `node server.js`
[nodemon] watching 72,981 files - this might cause high cpu usage. To reduce use "--watch"

nodemon 的默認行為是監視項目根目錄下的所有目錄，并忽略一些目錄，如 node_modules、bower_components 或 .sass_cache.這個默認的 ignore 實際上不起作用，但已在 此 PR 中修復.應用此修復程序，我的輸出與預期一樣.

The default behavior of nodemon is to watch all the directories in the root of your project, and to ignore some directories like node_modules, bower_components or .sass_cache. This default ignore don't work actually, but was fixed in this PR. Applying this fix, my output was just as expected.

> nodemon --watch app server.js
[nodemon] v1.2.1
[nodemon] to restart at any time, enter `rs`
[nodemon] watching: app/**/*
[nodemon] starting `node server.js`

我使用這兩種配置進行了測試，即使出現警告，我的 nodemon 也沒有刷新不在指定 watched 目錄中的文件更改，并且正常工作正如預期的那樣，沒有性能問題.這更可能是對我的誤報警告.

I tested using both configurations, and even with the warning, my nodemon was not refreshing on a file change that is not in the specified watched directory, and working just as expected with no performance issue. It's more likely a false-positive warning to me.

但現在我建議您堅持使用 ignore 規則，直到將其合并到 nodemon 或找到其他解決方法.

But for now I advice you to stay with your ignore rule until this is merged into nodemon or another workaround is found.
