bitshares-ui的README.md写得很简单，别人也很简单的执行即可，想不到我还得写篇文章来记录，在过程中碰到几处问题，其实网上也不少人碰到类似问题，记录一下。

npm install下载不动问题

现象：

要不就卡在下载，要不就下载超时，如下：

Downloading electron-v1.8.4-darwin-x64.zip
Error: connect ETIMEDOUT 54.231.49.80:443

Downloading electron-v1.8.4-darwin-x64.zip
[>                                            ] 0.6% of 48.34 MB (3.18 kB/s)

解决方法：

先安装cnpm，然后用cnpm下载

Chaim:bitshares-ui Chaim$ npm install cnpm -g --registry=https://registry.npm.taobao.org
Chaim:bitshares-ui Chaim$ cnpm install

Module not found: Error: Can't resolve

现象：

ERROR in ./app/components/Wallet/WalletUnlockModal.jsx
Module not found: Error: Can't resolve 'react-foundation-apps/src/utils/foundation-api' in '/Users/Chaim/Documents/workspace/bitshares-ui/app/components/Wallet'
 @ ./app/components/Wallet/WalletUnlockModal.jsx 12:0-67

 @ ./app/Routes-dev.jsx
 @ ./app/index-dev.js
 @ ./app/Main-dev.js
 @ multi react-hot-loader/patch webpack-hot-middleware/client ./app/Main-dev.js

解决方法：

Chaim:bitshares-ui Chaim$ cnpm install react-foundation-apps --save-dev
⠋ [react-foundation-apps@git+https://github.com/valzav/react-foundation-apps.git] install react-foundation-apps from git git+https://github.com/valzav/react-foundation-apps.git, may be very slow, please keep patience
✔ Installed 1 packages
✔ Linked 0 latest versions
✔ Run 0 scripts
✔ All packages installed (1 packages installed from git, used 5s, speed 0B/s, json 0(0B), tarball 0B)

can't resolve 的问题都用此方法解决。

Unexpected token

现象：

ERROR in ./node_modules/_react-foundation-apps@0.7.0@react-foundation-apps/src/trigger/index.jsx
Module parse failed: Unexpected token (59:13)
You may need an appropriate loader to handle this file type.

解决方案：

又报这错误，查了很多资料，有说是node版本不对，升级到最新node9.6.1也一样，有说是babel-loader版本6.x.x不行要用5.x.x，装了5.0.0试一下，这个错误不报了又报其它的错误，哎~

Module build failed: ReferenceError:

ERROR in ./app/Main-dev.js
Module build failed: ReferenceError: [BABEL] /Users/Chaim/Documents/workspace/bitshares-ui/app/Main-dev.js: Unknown option: /Users/Chaim/Documents/workspace/bitshares-ui/.babelrc.presets
    at Logger.error (/Users/Chaim/Documents/workspace/bitshares-ui/node_modules/_babel-core@5.8.38@babel-core/lib/transformation/file/logger.js:58:11)

解决方案：

还是安装nvm，从头来一遍吧！

sudo rm -rf /usr/local/lib/node_modules #删除全局 node_modules 目录
sudo rm /usr/local/bin/node #删除 node
cd  /usr/local/bin && ls -l | grep "../lib/node_modules/" | awk '{print $9}'| xargs rm #删除全局 node 模块注册的软链

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.30.2/install.sh | bash
nvm install v6
nvm use v6

Module parse failed: Unexpected token

重新安装一遍还是同样的问题，nodejs这一套本来就不甚熟悉！

想了下整个过程，除了在npm install时用了cnpm install之外，没有任何不同，用npm install再安装一遍！

npm install报权限错误，sudo安装再试一遍：

localhost:bitshares-ui Chaim$ sudo npm install
localhost:bitshares-ui Chaim$ npm start
...
     [458] ./node_modules/bitsharesjs/es/chain/src/TransactionBuilder.js 24.1 kB {0} [built]
