python - weasyprint - 在 ubuntu 中安装。

Question

我试图使用命令“pip install weasyprint”安装 weasyprint。

它给了我错误：

requests 2.18.4 has requirement chardet<3.1.0,>=3.0.2, but you'll have 
chardet 2.3.0 which is incompatible.
tensorboard 1.8.0 has requirement html5lib==0.9999999, but you'll have 
html5lib 1.0.1 which is incompatible.
bleach 1.5.0 has requirement html5lib!=0.9999,!=0.99999, 
<0.99999999,>=0.999, but you'll have html5lib 1.0.1 which is 
incompatible.

有谁知道如何修理它？
