httpie - Python-powered HTTP CLI for humans

keitheis — Mon, 19 Mar 2012 12:27:48 +0800

httpie - Python-powered HTTP CLI for humans:

另一個建立於 Requests 上的 HTTP command line 套件，看起來很方便。

thechangelog:

Although cURL is great, we’re always looking for great console tools for working with HTTP. Jakub Roztocil has released HTTPie. Built on Requests, HTTPie provides a clean command line interface for HTTP requests:
http PATCH api.example.com/person/1 X-API-Token:123 name=John email=john@example.org PATCH /person/1 HTTP/1.1 User-Agent: HTTPie/0.1 X-API-Token: 123 Content-Type: application/json; charset=utf-8 {"name": "John", "email": "john@example.org"} 
I appreciate the colored terminal output:

Using perfarce with Mercurial 1.9

build Psycopg2 failed on Windows

keitheis — Tue, 28 Jun 2011 18:33:45 +0800

每個時代都在遇到的問題：套件TMD裝不起來。

就腳本語言(script language)來說，套件在 Windows 上的問題還滿嚴重的。

pip install Psycopg2

.\psycopg/lobject.h(29) : fatal error C1083: Cannot open include file: ‘libpq/li

bpq-fs.h’: No such file or directory

這時可以指定 pc_config.exe 這樣自己來 build 看看(參考)：

cd build\Psycopg2

python setup.py build_ext —pg-config=C:\path\to\pg_config.exe build

build 成功的話可以 pip install Psycopg2 了

如果在安裝時若出現 “mt.exe” not found…

則需要把 xxx 版的 Windows SDK 加入環境變數的路徑(Path)

例：C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin

有點髒的解法，給混沌的世界。

building 'sqlalchemy.cprocessors' extension failed on Windows

keitheis — Tue, 28 Jun 2011 16:54:00 +0800

在 Windows 上 pip install SQLAlchemy 出現

Traceback (most recent call last):

File “<string>”, line 1, in <module>

File “.\build\SQLAlchemy\setup.py”, line 287, in <module>

“Retrying the build without the C extension now.”

File “.\build\SQLAlchemy\setup.py”, line 90, in status_msgs

print(msg)

UnicodeEncodeError: ‘ascii’ codec can’t encode characters in position 0-6: ordinal not in range(128)

的繞道方式：

用編輯器打開 build\SQLAlchemy\setup.py

把這四行註解起來：

# Extension(‘sqlalchemy.cprocessors’,

# sources=[‘lib/sqlalchemy/cextension/processors.c’]),

# Extension(‘sqlalchemy.cresultproxy’,

# sources=[‘lib/sqlalchemy/cextension/resultproxy.c’])

再試著裝一次

pip install SQLAlchemy

即可能解決。

這樣不編 C extension 會影響 SQLAlchemy 在 Windows 上的效能，但我想通常不會認真要用這個 Windows 當作正式發佈的平台。不幸如此？保佑了。

6/29 更新：

編不起來可能是環境變數 Path 出了問題，可以檢查一下有沒有被什麼套件(類似 Zenxxx Server 之類) 亂加了雙引號。

在 Windows、Linux，以及 Mac 上安裝 pip - Python 套件管理程式

keitheis — Mon, 20 Jun 2011 12:45:00 +0800

這篇是寫給沒用過 virtualenv 與 pip 的 Python 套件管理攻略。

PycTW 2011 上應該沒時間講這種事，還是先在這邊還攻略債吧。

步驟

先講一下原則上的建議安裝方式（同 pip 官方文件上的建議）：利用 virtualenv 內建的 pip

下載 virtualenv.py
python virtualenv.py [新專案環境目錄名]
進入 virtualenv 環境(在這個環境下安裝的東西不會影響到整個系統)
開始使用 pip 安裝套件

Linux 或 Mac 上的指令參考

$ curl -O https://raw.github.com/pypa/virtualenv/master/virtualenv.py
$ python virtualenv.py my_new_env
$ . my_new_env/bin/activate
(my_new_env)$ pip install ...

通常這樣就完成了 Linux 與 Mac 上的攻略。

Windows 上的指令參考

儲存那個網頁，命名檔案為 virtualenv.py
打開 terminal(cmd.exe 之類的)，cd 到你要放專案資料夾的地方 (例： cd C:\Users\Keith )
python virtualenv.py my_new_env
my_new_env\Scripts\activate.bat
pip install …
