pip install py-find-1st 在使用 python3.9 的 ubuntu 20 上失敗

Question

賞金將在 4 天后到期。 這個問題的答案有資格獲得+50聲望獎勵。 Sam想引起更多人對這個問題的關注。

這是我的過程。

我在 ubuntu20 上啟動了一個新的 aws t2.micro ec2 並運行這個腳本

sudo apt-get update
sudo apt-get install gcc
sudo apt-get install python3.9
sudo apt-get install python3.9-venv
curl --silent --show-error --retry 5 https://bootstrap.pypa.io/get-pip.py > get-pip.py
python3.9 get-pip.py
sudo apt-get install python-dev
sudo apt-get install python3-dev
python3.9 -m pip install --upgrade pip
python3.9 -m pip install --upgrade pip setuptools
python3.9 -m pip install --upgrade wheel
python3.9 -m pip install testresources
sudo apt-get install build-essential
sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev libffi-dev wget liblzma-dev lzma
sudo apt-get install python3-devel
python3.9 -m pip install p5py
python3.9 -m pip install PEP517
python3.9 -m pip install py-find-1st

最后一行是問題

我得到了這個輸出（錯誤在底部，我包含了更多輸出以防它有幫助，不得不稍微修剪輸出）

如果您想重現該錯誤，您可以啟動一個運行 ubuntu20 的 t2.micro ec2 並運行上面列出的腳本

Answer 1

這似乎是您嘗試安裝的模塊的問題，而不是標頭本身。 py-find-1st是一個相當奇特的模塊（撰寫本文時在 GitHub 上有 9 顆星），並且已經報告了此類構建問題。

解決方案：

安裝 libpython3.9

sudo apt install libpython3.9-dev

編輯：此解決方案有效，OP 缺少libpython3.9-dev中的include/python3.9/Python.h標頭。

忘記那個模塊

該模塊實現了一個用於“查找第一個索引而不需要讀取完整數組”的函數，它（部分）可以實現為：

def find_1st(X):
    ind = np.flatnonzero(X < 0.)
    if len(ind) :
        return ind[0]
    else:
        return -1

問題是，這會讀取完整的數組。 如果數組太大，您可以考慮在循環中運行它。
