Streamlit安装失败的GitLab CI与UnicodeEncodeError

Question

在GitLab CI上，在将streamlit升级到1.10.0后，我在运行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。

我怎么解决它?

Answer 1

这个bug是由Streamlit 1.10.0引入的。streamlit hello命令引入多页特性后，新增摄像机表情: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:

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

，现在它工作了。

感谢比尔的回答。
