Ubuntu中streamlit安装后streamlit命令无法使用

在Ubuntu中，如果已经安装了streamlit，但是在终端中输入streamlit命令无法使用，可能是因为streamlit的可执行文件没有被添加到系统的环境变量中。可以通过以下步骤解决该问题：

1. 打开终端，输入以下命令打开.bashrc文件：

nano ~/.bashrc

2. 在文件末尾添加以下内容：

export PATH="$PATH:/home/username/.local/bin"

其中，username应该替换为你的用户名。

3. 按下Ctrl+X，输入Y保存文件并退出。

4. 输入以下命令使修改生效：

source ~/.bashrc

5. 现在在终端中输入streamlit命令应该就可以正常使用了。
