用webui.sh安装报错No module named ‘importlib.metadata‘_cannot locate tcmalloc. do you have tcmalloc or go

安装sdweb报错，出现No module named 'importlib.metadata：

glibc version is 2.35
Cannot locate TCMalloc. Do you have tcmalloc or google-perftool installed on your system? (improves CPU memory usage)

解决，退出conda环境，删除之前在stable-diffusion-webui/中的venv的文件夹，然后再试试。

退出conda环境指令：

conda deactivate

退出指令多执行几次，直到前面没小括号。
