【问题描述】：
我的机器经常出现奇怪的问题。每次我安装一些新的 npm 依赖项时，gulp 都会神奇地从 node_modules 文件夹中消失。
gulp 目前作为 devDependency 安装为："gulp": "github:gulpjs/gulp"
如果我发出通常的npm install 一切都会恢复正常
非常清楚：
$ npm install github:gulpjs/gulp --save-dev
npm WARN ajv-keywords@3.2.0 requires a peer of ajv@^6.0.0 but none is installed. You must install peer dependencies yourself.
+ gulp@4.0.0
added 183 packages in 26.452s
然后如果我尝试安装新的东西...
$ npm install eyeglass --verbose
npm info it worked if it ends with ok
npm verb cli [ '/Users/peach/.nvm/versions/node/v8.11.3/bin/node',
npm verb cli '/Users/peach/.nvm/versions/node/v8.11.3/bin/npm',
npm verb cli 'install',
npm verb cli 'eyeglass',
npm verb cli '--verbose' ]

npm verb unbuild rmStuff gulp@4.0.0 from /Users/peach/repos/sotb-six/node_modules

...
+ eyeglass@1.5.0
removed 183 packages and updated 1 package in 10.707s
npm verb exit [ 0, true ]
npm info ok
接下来是很多其他的包删除...
不知道发生了什么，我很不幸试图为此找到解决方案
使用npm@5.6.0 和node@v8.11.3
[edit] 尝试删除 package-lock.json 并重新安装 gulp，然后分别安装 $whateverpackage，但结果相同。
$ rm package-lock.json
$ npm install github:gulpjs/gulp
npm notice created a lockfile as package-lock.json. You should commit this file.
npm WARN ajv-keywords@3.2.0 requires a peer of ajv@^6.0.0 but none is installed. You must install peer dependencies yourself.
+ gulp@4.0.0
added 183 packages in 32.953s
$ ls -l node_modules/.bin/gulp
lrwxr-xr-x 1 peach staff 19 Jul 9 13:24 node_modules/.bin/gulp -> ../gulp/bin/gulp.js
$ npm install eyeglass
npm WARN ajv-keywords@3.2.0 requires a peer of ajv@^6.0.0 but none is installed. You must install peer dependencies yourself.

$ ls -l node_modules/.bin/gulp

【问题讨论】：
-
node_modules/gulp还在吗？ -
不。它被完全卸载了。 （它是被删除的 183 个软件包的一部分）
-
到目前为止我发现： • 使用 npm 6.1 而不是 5.6 时有效 • 使用
npm install eyeglass --save时有效 • 使用npm install eyeglass --no-dev时有效 您能确认这些发现吗？跨度> -
@RaphaelSchweikert 可以确认，npm 5* 将被删除，6 保持 gulp，无论选项如何（不带选项运行并且按预期工作）。
-
是的，npm 6 可以正常工作，但对我来说，5.6 也可以（至少有时）使用这些选项。
