大家好，又见面了，我是你们的朋友全栈君。

错误如下：

解决方法：

修改src/chrome/browser/resources/tools/optimize_webui.py下，

for bundled_file in bundled_paths:
    with open(bundled_file, 'r') as f:
      output = f.read()
      assert "<if expr" not in output, \
          'Unexpected <if expr> found in bundled output. Check that all ' + \
          'input files using such expressions are preprocessed.'

改为

for bundled_file in bundled_paths:
    with open(bundled_file, 'r',  encoding='gb18030', errors='ignore') as f:
      output = f.read()
      assert "<if expr" not in output, \
          'Unexpected <if expr> found in bundled output. Check that all ' + \
          'input files using such expressions are preprocessed.'
