[英]Error: command 'gcc' failed with exit status 1 while installing crf++
我試圖在Macbook中安裝crf ++。 我從https://taku910.github.io/crfpp/#download下載了CRF ++-0.58。 然后我按照crf ++的官方網站上的說明進行操作。
我首先進入名為CRF ++-0.58的文件夾。 然后我在終端中輸入以下代碼:
make
sudo make install
cd python
這些命令運行良好。 然后我輸入
python setup.py install
輸出如下:
running build
running build_py
running build_ext

然后,我在線搜索錯誤“錯誤:命令'gcc'失敗,退出狀態為1”。 我發現遇到類似問題的人。 我嘗試了一些解決方案,但沒有一個起作用。
我嘗試安裝python-dev來解決此問題,但失敗了。
(base) localhost:python dxm$ brew install python3-dev
Error: No available formula with the name "python3-dev"
==> Searching for a previously deleted formula (in the last month)...
Warning: homebrew/core is shallow clone. To get complete history run:
git -C "$(brew --repo homebrew/core)" fetch --unshallow
Error: No previously deleted formula found.
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...`enter code here`
==> Searching taps on GitHub...
Error: No formulae found in taps.
那么我該如何解決這個問題呢?
我發現蘋果提供了一種安裝crf ++的方法,它與我嘗試的完全不同: http : //macappstore.org/crf/
通過這種方式安裝后,我可以像這樣使用crf ++:
crf_train = "crf_learn -f 3 template.txt dg_train.txt dg_model"
os.system(crf_train)
crf_test = "crf_test -m dg_model dg_test.txt -o dg_result.txt"
os.system(crf_test)
