Python locust 在 AWS 實例中不起作用

Question

我正在嘗試在 ec2 實例中使用 locust 對我的項目進行負載測試。 所以，我已經使用這個命令安裝了 locust：

python -m pip install locustio

我得到以下回復：

我在想，locust 已經安裝好了。 但是當我執行我的 python 腳本來啟動服務器時，它說如下：

bash: locust: command not found

任何人都可以幫我理解這里出了什么問題嗎？ 提前致謝。

Answer 1

ec2 實例不一定在通常的目錄中安裝東西。

我建議運行如下命令：

find / -name locust 2>/dev/null

這將顯示 locust 的安裝位置（可能在 /home/{user}/.local/bin 之類的地方）

將此添加到您的路徑（或您在上述命令中找到的任何目錄）：

export PATH=$PATH:/home/{user}/.local/bin

之后，您的 shell 應該能夠找到該命令。
