茶叶蛋 run dev 路径问题

[waitingsong]

• Node Version: 8.10.0
• Egg Version: 2.6.0
• Plugin Name:
• Plugin Version:
• Platform:
• Mini Showcase Repository:

参照 本文 步骤

$ npx egg-init --type=ts showcase
$ cd showcase && npm i
$ npm run dev

中途出现错误，把 node_modules 改名为 node_modules0 （因为删除目录比较卡所以习惯是改名后重新执行 npm i）。 然后再执行 npm run dev 就报错了

$ npm run dev

为何会去读取 '...\node_modules0\babel-plugin-tran 这个目录呢

然后执行 npm run clean 继续出错

$ npm run clean

> [email protected] clean E:\project\egg\eggjs-examples\framework-ts2\yadan
> ets clean

module.js:549
    throw err;
    ^

...\yadan\bin-clean 这个路径更奇特了

删除 node_modules0 目录后正常。
按理说没有驻留程序，修改了 node_modules 目录重新 npm i 不会有副作用的。我在测试 ng, ionic 以及其他程序时也这么改名干着从来没遇到过类似问题。

在我的机子上 run clean 没出现问题，但是 run dev 会抛错，不过错误信息跟你的不一样，ts 会去扫描目录下所有目录，除了 node_modules 目录，但是如果你只是把 node_modules 改成 node_modules0 ，那么 ts 就也会去扫描，怀疑是这一块导致出了什么问题.

[waitingsong]

我其他项目的 tsconfig.json 里面一般都有个排除条目 'node_modules*' (有个星号结尾) 。应该是这个生效避免了些问题吧

[waitingsong]

添加忽略目录后问题解决
