Nodejs Error: Cannot find module 'unicode/category/So'

Error: Cannot find module ‘unicode/category/So’

前幾天用了keystonejs，一個node開發的不錯的CMS架構，在把代碼部署到一台新的阿裡雲機器後，出現了一些問題。

由于npm某些包被GFW牆掉，是以我在阿裡雲使用了cnpm，cnpm安裝如下：

npm install -g cnpm --registry=https://registry.npm.taobao.org
ln -s /usr/local/node/bin/cnpm /usr/local/bin/cnpm #為cnpm建立軟連接配接
           

使用cnpm安裝package.json中的依賴包。日志如下，中間忽略部分module的安裝。

[Error: Run “sh -c node-gyp rebuild” error, exit code 127**

悲劇是從這裡開始的。buffertools工具需要node-gyp rebuild，但是我環境裡并沒有安裝node-gyp

啟動node keystone.js後開始報錯

如下

module.js:341
    throw err;
    ^

Error: Cannot find module 'unicode/category/So'
    at Function.Module._resolveFilename (module.js:339:15)
    at Function.Module._load (module.js:290:25)
    at Module.require (module.js:367:17)
    at require (internal/module.js:16:19)
           

缺少unicode/category/So，我以為缺少unicode包，繼續用cnpm install unicode來安裝。結果提示

[unicode@*] existed at node_modules/.npminstall/unicode//unicode ( packages, use ms, speed kB/s, json kB, tarball B)
All packages installed (use ms, speed kB/s, json (kB), tarball B)
           

但是進入node_module/unicode後發現裡面并沒有So等檔案

使用npm install unicode安裝

提示

npm WARN skippingAction Module is inside a symlinked module: not running remove babel-runtime@ node_modules/keystone/node_modules/babel-core/node_modules/babel-template/node_modules/babel-runtime
.......
           

因為node_modules/.npminstall裡已經有了unicode的軟連接配接。

使用cnpm unistall unicode，結果提示如下

- [email protected] node_modules/unicode
npm WARN enoent ENOENT: no such file or directory, open '/root/juyou_server_cms/node_modules/.npminstall/unicode/0.6.1/unicode/category/package.json'
npm WARN category No description
npm WARN category No repository field.
npm WARN category No README data
npm WARN category No license field.
           

因為沒有被正确的安裝，是以也沒法解除安裝。

1. 手動删除了node_modules下的unicode，并删除了.npminstall下的所有軟連結。
2. cnpm install -g node-gyp，安裝node-gyp
3. cnpm install unicode，重新安裝unicode子產品

這次終于成功的安裝了unicode子產品，使用nohup node keystone.js &後順利的啟動了keystone.js
