Firefox：編譯錯誤“'ascii'編解碼器無法編碼字符”

Question

我嘗試編譯Firefox，因為我做了一些更改。 但是，當我嘗試編譯這些東西時，出現此錯誤：

   Exception in thread Thread-1:

我的構建系統是ArchLinux 64bit。 我的更改基於Firefox 25源。 我只更改設計的東西，沒有代碼。

Answer 1

有問題的代碼實際上只是將某些內容記錄到stdout。 看來您的stdout（Terminal？）不是utf-8或類似的Python已知編碼。 嘗試將您的locale為明智的locale ，最好是utf-8。

您可以通過執行python -c "import sys; print sys.stdout.encoding"來檢查python將使用的stdout編碼python -c "import sys; print sys.stdout.encoding"

Answer 2

嘗試在腳本開始時添加以下內容：

import sys
sys.setdefaultencoding("utf-8")
