Virtualenv: Virtualenv tidak dapat menyalin pustaka bawaan

Dibuat pada 9 Des 2020  ·  8Komentar  ·  Sumber: pypa/virtualenv

Isu

Saya membuat lingkungan virtual, direktori / lib / Python tidak memiliki perpustakaan bawaan (hanya paket situs).
Karena saya akan menggunakannya.

Lingkungan Hidup
python: 3.8.1
Sediakan setidaknya:

  • OS: Centos7.8
  • pip list dari host python di mana virtualenv diinstal:

Output dari pembuatan lingkungan virtual

Pastikan untuk menjalankan pembuatan dengan -vvv --with-traceback :

Itu hanya menyalin sebagian dari paket bawaan, dan itu hanya untuk python 2.

Saya membuat lingkungan virtual, direktori / lib / Python tidak memiliki perpustakaan bawaan (hanya paket situs).
Karena saya akan menggunakannya.

Itu memang disengaja. Anda mungkin perlu menjelaskan lebih lanjut tentang bagaimana Anda ingin menggunakannya dan mengapa.

Saya ingin mengemas lingkungan virtual, menjalankannya di mesin yang berbeda./python3.

Saya tahu saya mungkin seharusnya tidak mengajukan pertanyaan di sini, tetapi saya benar-benar tidak tahu harus pergi ke mana, jadi saya minta maaf.

Harap berikan panduan langkah demi langkah mendetail tentang cara Anda sampai di sana. Idealnya gambar buruh pelabuhan.

  1. Kompilasi python381
  2. Instal pip virtualenv
  3. Buat lingkungan virtual ./virtualenv -vvv --always-copy --clear / opt / env_test
  4. Salin file libpython3.8.so.1.0 ke / opt / env_test / lib
  5. Kompres / opt / env_test
  6. scp ke komputer lain dan dekompresi
  7. Setel LD_LIBRARY_PATH ke libpython3.8.so.1.0
  8. / env_test / bin / python3

lingkungan virtual adalah referensi ke ular sanca global, dan tidak dimaksudkan untuk hidup sendiri. Mereka tidak dimaksudkan untuk disalin ke komputer lain. Dan mereka tidak akan berfungsi kecuali Anda juga menyalin python global dan membuat lingkungan virtual dalam mode salin. Lihat https://www.youtube.com/watch?v=o1Vue9CWRxU
