如何修正发射Voila时的jinja错误？

Question

我试图第一次在Voila查看我的木星实验室图表，当我从命令提示符$ voila <filename>运行Voila时，我得到以下跟踪：

[Voila] Using C:\Users\B****~1\AppData\Local\Temp to store connection files

我通过conda安装了voila0.2.16(与mamba有问题)，并在Windows计算机上使用Python3.9.7。

解决了这个问题。Conda正在自动安装Voila的旧版本，这与我的Python或木星版本都不兼容。安装通过pip加载的最新版本0.3.2，它现在正在工作。
