如何解決TemplateRuntimeError：編譯鉻時沒有名為'>'的測試？

Question

編譯鉻時，我收到以下錯誤消息：

我不確定它是否與 jinja2 的版本有關。 我的肯定是v2.8。

autoninja -C out/Default對我來說沒問題。 當我嘗試在 Ubuntu 16.04 上編譯 CrOS 時，會出現此問題。

autoninja -C out/Cros chrome也很好。 @_@

Answer 1

找出原因。 因為那個忍者在系統中使用的是jinja2，而不是src/third_party目錄下的版本。

我通過卸載系統 jinja2 解決了這個問題。
