Jupyter 支援不同的 Kernel，此處記錄如何於 Termux 上安裝 javascript kernel。
(Kernel 可理解為 programming language)
安裝流程：
[1] Nodejs
apt install nodejs
| $ node --version v14.2.0 $ npm --version 6.14.4 |
[2] ijavascript
npm -g install ijavascript （勿直接安裝，會出現 zmq 相關問題）
使用 npm 直接安裝 ijavascript 或 zeromp 都會產生編譯問題而失敗，需用 --zmq-external 選項來使用原先透過 apt install libzmq（4.3.2-2）安裝好的 libzmq 以避免編譯問題。另外，-g 選項也是必要的：
npm -g install ijavascript --zmq-external
| $ npm -g install ijavascript --zmq-external /data/data/com.termux/files/usr/bin/ijs -> /data/data/com.termux/files/usr/lib/node_modules/ijavascript/bin/ijavascript.js /data/data/com.termux/files/usr/bin/ijsinstall -> /data/data/com.termux/files/usr/lib/node_modules/ijavascript/bin/ijsinstall.js /data/data/com.termux/files/usr/bin/ijskernel -> /data/data/com.termux/files/usr/lib/node_modules/ijavascript/lib/kernel.js /data/data/com.termux/files/usr/bin/ijsnotebook -> /data/data/com.termux/files/usr/lib/node_modules/ijavascript/bin/ijsnotebook.js /data/data/com.termux/files/usr/bin/ijsconsole -> /data/data/com.termux/files/usr/lib/node_modules/ijavascript/bin/ijsconsole.js > zeromq@5.2.0 install /data/data/com.termux/files/usr/lib/node_modules/ijavascript/node_modules/zeromq > node scripts/prebuild-install.js || (node scripts/preinstall.js && node-gyp rebuild) Requested to use external libzmq.

安裝後位於 /data/data/com.termux/files/usr/lib/node_modules
[3] ijsinstall
直接執行 ijsinstall 進行安裝
[4] 執行
<1> 登入 jupyter lab 後即可看到 javascript (Node.js) 選項（若已登入按重新整理瀏覽器即會出現）
<2> 在 ipynb 中測試 javascript 程式碼
Troubleshooting：
[1] 若執行 npm -g install ijavascript（沒有 --zmq-external 選項時），會出現安裝錯誤：
| configure: error: None of '' are valid pollers on this platform child process exited with code 1 |
需透過下面指令反安裝：
npm uninstall ijavascript
[2] 若執行 npm install ijavascript --zmq-external（沒有 -g 選項時）：
會安裝於 home/node_modules 下，導致系統先取用 home/node_modules/ijavascript，後續執行 ijsinstall 會有錯誤：
| $ ijsinstall ….. [I 13:24:58.314 LabApp] KernelRestarter: restarting kernel (4/5), new random ports internal/modules/cjs/loader.js:1226 return process.dlopen(module, path.toNamespacedPath(filename)); ^ Error: dlopen failed: cannot locate symbol "zmq_msg_init" referenced by |
若曾使用沒有 -g 選項的 npm install ijavascript 或 npm install ijavascript --zmq-external，需先移除:
npm uninstall ijavascript
