Baik, saatnya puisi kecil untuk pejuang logika digital. Pantun bukan algoritma, tapi ritmenya juga perlu rapi supaya compiler kehidupan tidak error karna logika.
- Naik sepeda ke tempat angringan,
- Bawa laptop sambil tersenyum sopan.
- Kalau kode sering berantakan,
- Sabar… bug itu cuma ujian keimanan
- Makan mie instan dua porsi bareng-bareng,
- Sambil commit patch di repository terang-terang.
- Jika hasil kerja belum dipuji orang,
- Santai… kode bagus lama-lama sendiri yang gemilang.

pip install streamlit --no-cache-dirgit clone https://github.com/DwiDevelopes/Launcher.git
cd Launcher/build/lib/streamlit_launcherpip install -r requirements.txt --no-cache-dirstreamlit run dashboard.py --server.address=0.0.0.0 --server.port=8501Install modul manual, contoh:
pip install streamlit
pip install pandas
pip install numpy
pip install plotly
pip install matplotlib
pip install seaborn
pip install wordcloud
pip install streamlit-folium
pip install graphviz
pip install pillow
pip install pydeck
pip install scipy

pip install xgboost
pip install statsmodels
pip install tensorflow-cpu
pip install keras
pip install networkx
pip install rich
pip install requests
pip install openpyxl
pip install xlrd
pip install numpy-stl
pip install trimesh
pip install streamlit-modal
pip install opencv-python-headless
pip install mlxtend| Masalah | Solusi |
|---|---|
| Streamlit gagal build | Pastikan clang, cmake, openssl, libffi sudah terinstall |
| Termux tidak buka web UI | Buka dari browser HP ke http://localhost:8501 |
| Masih error | Coba termux-chroot (kalau pakai proot distro) |
Berikut resep terminal layaknya koki DevOps yang sedang menyiapkan dapur Termux agar Streamlit mau nurut. Ini adalah file install_streamlit_termux.sh yang tinggal kamu simpan dan eksekusi.
Script ini memastikan dependency, pip builder, dan repo Launcher terpasang rapi tanpa drama.
chmod +x install_streamlit_termux.sh
./install_streamlit_termux.shJika sukses, buka browser Android lalu masuk ke:
http://localhost:8501
- Script ini tidak menghapus environment lama; aman untuk update
- coffie panas opsional, tapi bikin suasana ngoding lebih damai
Menjalankan install_streamlit_termux.sh itu seperti membangunkan naga kecil di Termux: perlu sedikit ritual, tapi setelah hidup, dia akan menghembuskan Streamlit dari pori-pori ponselmu.
-
Masuk ke folder tempat file disimpan Misal file ada di
~/(home):cd ~
-
Pastikan file punya izin eksekusi
chmod +x install_streamlit_termux.sh
-
Jalankan script
./install_streamlit_termux.sh
Kalau kamu ingin menjalankan langsung via bash, boleh juga:
bash install_streamlit_termux.shKamu bisa buat file manual:
nano install_streamlit_termux.shPaste script ke dalamnya, lalu:
CTRL + O untuk save
ENTER
CTRL + X untuk keluar
Lanjut ke langkah chmod dan run di atas.
| Masalah | Solusi |
|---|---|
| Permission denied | Pastikan sudah chmod +x |
| Command not found | Pastikan berada di folder yang benar |
| Gagal install package | Coba jalankan ulang script, atau install termux-chroot jika pakai PRoot |
Bayangkan ini sebagai menu spell:
| Nomor | Mantra | Hasil |
|---|---|---|
| 1 | Auto-installer 1 baris | Tinggal copy-paste, semua terinstal otomatis |
| 2 | Installer + Virtual Env | Termux jadi rapi, paket terisolasi seperti laboratorium kimia |
| 3 | Termux Widget Shortcut | Tinggal tap ikon di Android, Streamlit langsung menyala |
| 4 | Systemd-like auto-restart script | Kalau Streamlit error, bangkit sendiri seperti zombie ramah |
| 5 | Full Linux magic (proot Ubuntu) | Streamlit jalan layaknya di PC, lebih stabil |
| 6 | Gabungan level Hokage | Semua opsi di atas, sistem jalan sendiri, kamu tinggal menyeruput kopi |
