在 GitLab CI 上，将 streamlit 升级到 1.10.0 后，运行 pip install streamlit 时出现以下错误：

ERROR: Exception:

UnicodeEncodeError: 'ascii' codec can't encode character '\U0001f4f9' in position 76: ordinal not in range(128)

我检查了错误的编码字符，它对应于摄像机表情符号???? = \U0001f4f9。

我该如何解决？

【解决方案1】：

Streamlit 1.10.0 引入了该错误。在引入多页功能后，streamlit hello 命令中添加了摄像机表情符号：https://github.com/streamlit/streamlit/tree/release/1.10.0/lib/streamlit/hello/pages

在我的 CI 中，编码如下：

$ locale || true
LANG=
LANGUAGE=
LC_CTYPE="POSIX"
LC_NUMERIC="POSIX"
LC_TIME="POSIX"
LC_COLLATE="POSIX"
LC_MONETARY="POSIX"
LC_MESSAGES="POSIX"
LC_PAPER="POSIX"
LC_NAME="POSIX"
LC_ADDRESS="POSIX"
LC_TELEPHONE="POSIX"
LC_MEASUREMENT="POSIX"
LC_IDENTIFICATION="POSIX"
LC_ALL=

我使用以下方法重置它们：

before_script:
    - apt-get install -y locales
    - echo "en_US UTF-8" > /etc/locale.gen
    - locale-gen en_US.UTF-8
    - export LANG=en_US.UTF-8
    - export LANGUAGE=en_US:en
    - export LC_ALL=en_US.UTF-8

现在它可以工作了。

感谢Bill's answer。
