尝试 locust -V 时出现权限错误

Question

我刚刚用pip install locust ，它安装在~/.local/lib/python3.8/site-packages 。
问题是如果我尝试使用locust -V获取它的版本，我会收到权限被拒绝错误。

> which locust
locust not found
> type locust
locust not found
> locust
zsh: permission denied: locust

~/.local/lib/python3.8/site-packages在 PATH 中

ls -lF $(which locust)和head -1 $(which locust)没有结果，因为which locust找不到它。

如果重新安装：

❯ pip install locust

Answer 1

非常感谢你的帮助。
问题是 locust 命令安装在~/.local/bin/locust ，并且不在路径中。

Answer 2

~/.local/lib/python3.8/site-packages不应该在你的路径上。

我认为问题在于 zsh 找到了蝗虫 package文件夹（位于~/.local/lib/python3.8/site-packages/locust/ ）并尝试执行它。

pip 应该将 locust 安装为命令（例如/usr/local/bin/locust ）。 尝试重新安装并在安装时检查是否有任何错误，因为如果 pip 安装在您路径之外的某个位置，它应该会记录一个警告。
